Which set of values could be the side length of a 30 60 90 triangle? A. {5,5v3,10}
Therefore, the answer is A. {5, 5√3, 10}.
The set of values {5, 5√3, 10} could be the side lengths of a 30-60-90 triangle.
In a 30-60-90 triangle, the sides are in a specific ratio. The ratio is 1 : √3 : 2, where the shortest side (opposite the 30-degree angle) has length x, the side opposite the 60-degree angle has length x√3, and the hypotenuse (opposite the 90-degree angle) has length 2x.
Let's check if the given set of values satisfies this ratio:
If x= 5, then the side opposite the 60-degree angle should be 5√3, and the hypotenuse should be 10. These values match the ratio, so the set {5, 5√3, 10} could be the side lengths of a 30-60-90 triangle.

if a₁=3 and aₙ=5aₙ-₁ then find the value of a₅
Answer:
The value of a₅ is 1875.
Step-by-step explanation:
Given:
a₁ = 3
aₙ = 5aₙ₋₁
To find the value of a₅, we can apply the recursive formula to compute each term successively:
Step 1: Compute a₂
a₂ = 5a₁ = 5(3) = 15
Step 2: Compute a₃
a₃ = 5a₂ = 5(15) = 75
Step 3: Compute a₄
a₄ = 5a₃ = 5(75) = 375
Step 4: Compute a₅
a₅ = 5a₄ = 5(375) = 1875
Tim needs to be at work at 8:00 A.M. It takes him 30 minutes to get ready in the morningand 15 minutes to drive to work. What is the latest time Tim can get up in the morningwithout being late for work?
The given information is:

Find the numbers with the following property three times the sum of four and a number is less than seven times the same number
Let's represent the number with the variable "x". According to the given property, we can write the following equation:
3(x + 4) < 7x
Now, let's solve this inequality to find the range of numbers that satisfy the property.
3x + 12 < 7x
Subtract 3x from both sides:
12 < 4x
Divide both sides by 4 (since the coefficient of x is 4):
3 < x
So, the range of numbers that satisfy the given property is x > 3.
Therefore, any number greater than 3 will satisfy the condition. For example, 4, 5, 6, 7, 8, etc.Step-by-step explanation:
the phone company charges $33 for having a smartphone plus $9.95 a month for 2gb. IF mark has only $146.43 to spend on a phone, how many months can he have the phone? inequalities
The number of months Mark can have the phone is given by the equation
A = 11.4 months
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of months be represented as = A
Now , the equation is
Now , the total amount with Mark = $ 146.43
The initial amount for the smartphone = $ 33
The amount per month for 2GB is = $ 9.95
So , the amount for A months = $ 9.95 ( A )
So , the equation will be
Initial amount for the smartphone + the amount for A months = total amount with Mark
Substituting the values in the equation , we get
33 + 9.95 ( A ) = 146.43 be equation (1)
On simplifying the equation , we get
Subtracting 33 on both sides of the equation , we get
9.95 ( A ) = 113.43
Divide by 9.95 on both sides of the equation , we get
A = 11.4 months
Therefore , the value of A is 11.4 months
Hence , the number of months is 11.4 months

Gordon is trying to save up $2000 for a new saxophone he makes 12.50 per hour at his job at the coffee shop but he needs to set aside half of his hourly wage to pay his regular bills How many 40-hour weeks will he need to work before he can afford the saxophone?
A. 320 Weeks
B. 40 Weeks
C. 8 Weeks
D. 6.25 Weeks
Answer:
he will need to work 8 40-hour weeks.
Explanation:
since gordon has to set aside half of his wage to pay his bills, he can only save $12.50 ÷ 2 = $6.25 for the saxophone.
we can find how much money gordon saves from a 40-hour week by multiplying this by 40: $6.25 × 40 = $250.
now, divide the total amount of money he has to save by the amount he saves each week: $2000 ÷ $250 = 8.
he will need to work 8 40-hour weeks before he can afford the saxophone.

What is the equation of the line that is perpendicular to
the given line and has an x-intercept of 6?
O y=-3x+8
O y=-3x+6
O y=x-8
O y = x-6
The equation of the line that is perpendicular to the line passing through (-4,4) and (4,-2) and has an x-intercept of 6 is: y = (4/3)x - 8.
What is slope ?
Slope is a measure of the steepness or slant of a line. It is defined as the ratio of the vertical change between two points on a line to the horizontal change between those same two points. In other words, slope is the change in y divided by the change in x.
The slope of a line can be positive, negative, zero, or undefined. A positive slope means that the line is rising from left to right, while a negative slope means that the line is falling from left to right. A slope of zero means that the line is horizontal, while an undefined slope means that the line is vertical.
The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).
According to the question:
First, we need to find the slope of the line passing through (-4,4) and (4,-2) using the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) = (-4,4) and (x2, y2) = (4,-2)
slope = (-2 - 4) / (4 - (-4)) = -6/8 = -3/4
The equation of a line perpendicular to this line will have a slope that is the negative reciprocal of the slope of the given line. That is,
slope of perpendicular line = -1 / (-3/4) = 4/3
Now we can use the slope-intercept form of a line to find the equation of the line with slope 4/3 that passes through the point (6,0), which is the x-intercept given in the question:
y = mx + b, where m is the slope and b is the y-intercept
Plugging in m = 4/3 and the point (6,0), we get:
0 = (4/3)(6) + b
b = -8
Therefore, the equation of the line that is perpendicular to the line passing through (-4,4) and (4,-2) and has an x-intercept of 6 is:
y = (4/3)x - 8
So the answer is: y = (4/3)x - 8.

For f(x) = 2 - x and g(x)= 3x +x+5, find the following functions.
a. (fog)(x); b. (gof)(x); c. (fog)(2); d. (gof)(2)
a. (fog)(x)=-3x²-x-3
(Simplify your answer.)
b. (gof)(x) = 3x² - 13x+19
(Simplify your answer.)
c. (fog)(2)= -17
d. (gof)(2)= ?
The answers are below.
a) (fog)(x) = f(g(x)) = 2 - ( 3x² +x+5) = -3x² - x - 3
b) (gof)(x) = g(f(x)) = 3*(2 - x)² + (2 - x) +5 = 3x² - 13x + 19
a) (fog)(2) = -3x² - x - 3 = -3*4 - 2 - 3 = -12 - 2 - 3 = -17
b) (gof)(2) = 3x² - 13x + 19 = 3*4 - 13*2 + 19 = 12 - 26 + 19 = 5
How to find the following functions?Just replace evaluate the function g(x)= 3x² +x+5 insode of the function f(x) = 2 - xfor the first one.
a) (fog)(x) = f(g(x)) = 2 - ( 3x² +x+5) = -3x² - x - 3
b) (gof)(x) = g(f(x)) = 3*(2 - x)² + (2 - x) +5 = 3x² - 13x + 19
ok, now that you have these two values, just evaluate the equations in x = 2 to get the rest.
a) (fog)(2) = -3x² - x - 3 = -3*4 - 2 - 3 = -12 - 2 - 3 = -17
b) (gof)(2) = 3x² - 13x + 19 = 3*4 - 13*2 + 19 = 12 - 26 + 19 = 5

Step-by-step explanation:
f(1)=0
f(n)=f(n−1)+2
Answer: f(n) = 2n - 2
Therefore, we can use this formula to find the value of f(n) for any positive integer n.
Step-by-step explanation: Using the given recursive formula:
f(1) = 0
f(n) = f(n-1) + 2
We can find the values of f(n) for different values of n:
f(1) = 0
f(2) = f(1) + 2 = 0 + 2 = 2
f(3) = f(2) + 2 = 2 + 2 = 4
f(4) = f(3) + 2 = 4 + 2 = 6
f(5) = f(4) + 2 = 6 + 2 = 8
And so on.
We can see that each term in the sequence is 2 more than the previous term. So, we can write the general formula for f(n) as:
f(n) = 2n - 2
Therefore, we can use this formula to find the value of f(n) for any positive integer n.

The value of the variable "x" is 11.
We have a triangle. The vertices of the triangle are K, L, and M. The side KM is extended from point M to point N. The measures of the angles MKL, LMN, and KLM are (3x + 19)°, (7x + 5)°, and (2x + 8)°, respectively. We need to find out the value of the variable "x".
The angles LMK and LMN form a linear pair. It means they are supplementary angles. The sum of the angles is 180°.
∠LMK + ∠LMN = 180°
∠LMK + (7x + 5)° = 180°
∠LMK = 180° - (7x + 5)°
In the triangle KLM, we will use the angle sum property of a triangle. The sum of all the angles in a triangle is equal to 180°.
∠K + ∠L + ∠M = 180°
(3x +19)° + (2x + 8)° + [180° - (7x + 5)°] = 180°
3x +19 + 2x + 8 + 180 - 7x - 5 = 180

At point (-3, 11), a linear equation of this line can be calculated in slope-intercept form as follows:
y - 11 = (1 - 11)/(-4 + 3)(x + 3)
Y - 11 = 10(x + 3)
y = 10x + 30 + 11
y = 10x + 41.
