The calculation \((9.04-8.23+21.954+81.0) \times 3.1416\) would have 4 significant figures.



To determine the number of significant figures in a calculation, we follow the rules for significant figures:

1. Addition and subtraction: The result should have the same number of decimal places as the measurement with the fewest decimal places.
2. Multiplication and division: The result should have the same number of significant figures as the measurement with the fewest significant figures.

Let's break down the calculation step by step:
\(9.04-8.23+21.954+81.0\) yields \(104.764\).

Now, multiplying this result by \(3.1416\) gives \(329.5719744\).

The measurement with the fewest significant figures in the calculation is \(3.1416\), which has 5 significant figures.

According to the rule for multiplication and division, the result should have the same number of significant figures as the measurement with the fewest significant figures. Hence, the result, \(329.5719744\), will be rounded to 4 significant figures.

Therefore, the calculation \((9.04-8.23+21.954+81.0) \times 3.1416\) would have 4 significant figures.

The measures of each term are; WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32.

WE are given that Z is the centroid of triangle. Since centroid is the centre point of the object. The point in which the three medians of the triangle intersect is the centroid of a triangle.

Given WR=87 SY=39 and YT=48

WS=39

As WS=WR

WY=WS+SY

WY=39+39=78

WZ=58

Now, ZR=WR-WZ

ZR=87-48=29

ZT=16

Similalry;

YZ=YT-ZT

=48-16=32

YZ=32

Hence, the measures are; WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32

Answer:

114

Step-by-step explanation:

The question relates to the sum of an arithmetic progression, A. P.

The count of numbers added, n = 50

The sum of the numbers, Sₙ = 3,250

The formula for the sum of an A. P. is given as follows;

\(S_n = \dfrac{n}{2} \left[2 \cdot a + (n - 1)\cdot d\right]\)

\(S_n = \dfrac{n}{2} \left[a + a_n\right]\)

Where;

a = The first term of set of numbers

d = The common difference between consecutive numbers

n = The number of terms = 50

aₙ = The last term, the largest of the integers

Therefore, we get;

The common difference of consecutive even integers numbers, d = 2

Plugging in the values gives;

3,250 = (50/2) × (2·a + (50 - 1) × 2) = 25 × (2·a + 49 × 2)

2·a = (3,250/25) - 49 × 2 = 32

a = 32/2 = 16

From  \(S_n = \dfrac{n}{2} \left[a + a_n\right]\), we have;

3,250/25 = 16 + aₙ

aₙ = 3,250/25 - 16 = 114

The largest of the integers, aₙ = 114.

The Pythagorean Theorem is explained in this problem.

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

The theorem is expressed as follows:

c² = a² + b².

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

To find \(\frac{dy}{dx}\) when x = 0, we first express y in terms of x and then differentiate with respect  to x. The derivative is found to be \(\frac{dy}{dx}\) = -2\(e^{x}\) - 2\(e^{-x}\).

Given the expression for y as y = \(u^{2}\) - u + 1 and u as u = \(e^{x}\) - \(e^{-x}\), we need to find \(\frac{dy}{dx}\) when x = 0. To do this, we first substitute the expression for u into y, which gives us y = \((e^{x}- e^{-x} )^{2}\) - \((e^{x}-e^{-x} )\) + 1.

Next, we differentiate y with respect to x using the chain rule. The chain rule states that if y = f(u) and u = g(x), then \(\frac{dy}{dx}\) = \(\frac{df}{du}\) x \(\frac{du}{dx}\). Applying the chain rule to our expression, we differentiate each term separately.

The derivative of the first term, \((e^{x}- e^{-x} )^{2}\), is obtained by applying the power rule, resulting in 2\((e^{x}-e^{-x} )\)\((e^{x}+e^{-x} )\). The derivative of the second term, -\((e^{x}-e^{-x} )\), simplifies to -2\((e^{x}+e^{-x} )\), and the derivative of the constant term, 1, is 0.

Adding these derivatives together, we get \(\frac{dy}{dx}\) = 2\((e^{x}-e^{-x} )\)\((e^{x}+e^{-x} )\) - 2\((e^{x}+e^{-x} )\). Since we are evaluating the derivative at x = 0, we substitute x = 0 into the expression to find \(\frac{dy}{dx}\) = -2\(e^{x}\) - 2\(e^{-x}\). Thus, when x = 0, \(\frac{dy}{dx}\) = -2-2 = -4.

The exact value of trigonometric expression tan(u+v) is 24/25.

We can use the identity:

tan(u + v) = (tan u + tan v)/(1 - tan u tan v)

First, we need to find the values of tan u and tan v using the given information:

tan u = sin u / cos u = (7/25) / (-4/5) = -7/20

tan v = sin v / cos v = sqrt(1 - cos^2 v) / cos v = sqrt(1 - 9/25) / (-3/5) = 4/5

Substituting these values in the formula for tan(u + v), we get:

tan(u + v) = (-7/20 + 4/5) / (1 + (-7/20)(4/5))

= (-9/20) / (9/20)

= -1

Therefore, tan(u + v) = -1.

describes the population of insects?

A. The population is decaying at a rate of 3% each month.

B. The population is decaying at a rate of 25% each month.

C. The population is growing at a rate of 75% each month.

D. The population is growing at a rate of 97% each month.

Answer:

A. The population is decaying at a rate of 3% each month.

Step-by-step explanation:

Given

\(p(t) = 1.75(0.97)^t\)

Required

True statement about the function

From the options, we can see that we are to answer the question on the basis of decay and growing rates.

An exponential form is:

\(y=ab^x\)

Compare to \(p(t) = 1.75(0.97)^t\)

\(b= 0.97\\\)

If \(b > 1\), then \(b = 1 + r\) r represents growth rate

else, \(b= 1-r\) r represents decay rate

Since b < 0.97:

\(0.97= 1-r\)

\(r = 1 - 0.97\)

\(r = 0.03\)

\(r = 3\%\)

\(r = 0.03\)

Step-by-step explanation:

LN is tangent to circle O at point M and QM is a diameter. The measure of ∠QML and ∠PMN are 90° and 63° respectively.

1) To Determine the degree measurement of ∠QML

Based on the Perpendicular Tangent Theorem, tangent lines are always perpendicular to a circle's radius at the point of intersection

So, the radius OM is perpendicular to line LN at point M.

Hence,

The value of ∠QML = 90°

2) To determine the degree measurement of angle PMN

∠QMN = ∠QMP + ∠PMN

By the angle addition postulate, we can calculate this measurement as follows:

∠QMN = 90°

∠QMP = 27°

Replace with and substitute the value of angle QML into the equation.

90° = 27° + ∠PMN

∠PMN = 90° - 27° = 63°

Therefore, the value of  ∠PMN is 63°

The equation of the plane is 14x - 9y - 16z = -22.

To find the equation of a plane, we need a point on the plane and the normal vector to the plane. Since the plane passes through the point (8, 0, -3), we know that any point on the plane will satisfy the equation 14x - 9y - 16z = k for some constant k. We can use the coordinates of the point to find k: 14(8) - 9(0) - 16(-3) = 182. So the equation of the plane is 14x - 9y - 16z = 182.

Alternatively, we can find two points on the plane (by setting t = 0 and t = 1 in the equation of the line) and then use their cross product to find the normal vector to the plane. The two points are (5, 0, 4) and (2, 1/4, 4/3). Their cross product is (-9/4, -16, 45/4), which is a normal vector to the plane. Dividing by the GCD of the coefficients, we get the equation 14x - 9y - 16z = -22. So, the equation of the plane is 14x - 9y - 16z = -22.

Question 1: The equations share the same slope, but different y-intercepts.

Question 2: Option B (y = 2x + 1)

Both equations are written in slope intercept form.

\(y = mx+b\\\\\text{m - slope}\\\text{b - y-intercept}\)

The equations we have are:

\(\left \{ {{y=2x} \atop {y=2x-7}} \right.\)

Both equations share the same slope of 2. However, they have different y-intercepts.

y = 2x can be written as y = 2x + 0.

Usually if you only have the slope in your equation then the y-intercept is the origin, or (0, 0).

The second equation's y-intercept is -7. It takes 'b's place.

We are given a graph and we need to find a equation.

According to the graph, the line passes at (0, 1). 1 is the y - intercept.

Since y = 2x + 1 is the only option with 1 as the y - intercept, it should be the correct answer.

I'll do the slope as well to verify our answer.

I will use the points (-1, -1) and (1, 3).

\(m=\frac{3-(-1)}{1-(-1)}=\frac{4}{2} =\boxed{2}\)

The correct answer should be \(y = 2x+1\).
