Answer:

  -3, 0, 5

Step-by-step explanation:

You want the zeros of P(x) = x³ − 2x² − 15x using the factored form.

We notice right away that x is a factor of every term. Factoring that out gives us a quadratic to factor:

  P(x) = x(x² -2x -15)

To factor this, we need two factors of -15 that have a sum of -2. The factors -5 and +3 have those properties. That means our factored form is ...

  P(x) = x(x +3)(x -5) . . . . factored form

This product will be zero when any of its factors is zero. Considering them one at a time, we find the zeros of P(x) to be ...

  x = 0

  x +3 = 0   ⇒   x = -3

  x -5 = 0   ⇒   x = 5

The zeros of P(x) are -3, 0, 5.

\(y=\frac{1}{3}x\)

*View attached graph*

Step-by-step explanation:

Point-slope: \(y-y_1=m(x-x_1)\)

m = slope (\(\frac{1}{3}\))

point (6,2)

\(y-y_1=m(x-x_1)\)

\(y-2=\frac{1}{3}(x-6)\)

\(y-2=\frac{1}{3}x-2\)

Answer: The answer is C

Step-by-step explanation: This is because the equation has a greater than or equal to sign (≥). This mean that there will be a closed dot. Also, when it comes to inequalities, the sign points to where the line will be drawn, (greater than is to the right and less than is to the left), which indicates that the answer is C

Answer:

1/25

Step-by-step explanation:

days in a week is 7

odds of being born on each 7 days is equal

x born = 7 days

pr(one separate baby) = 1 ÷ 5

pr(second separate baby) = 1 ÷ 5

pr(both being born on a school day) = 1/5 × 1/5

= 1/25

Answer:

8 (hopefully)

Step-by-step explanation:

Exponents and Fractions always get dealt with before Math Symbols and Parentheses.

But other than that, you ALWAYS do times or divide from left to right, than plus or minus left to right (unless there's a parentheses, go for the number in the parentheses).

2 by the power of 3 (or 2^3) splits into three twos.

2 * 2 = 4 * 2 = 8 (2^3 = 8)

7 * 8 = 56

56 divided by 4 = 14

8 + 14 = 22

Long story sort

2^3 + 7 * 8 */. 4

8 + 7 * 8 */. 4

8 + 56 */. 4

8 + 14

22

Now than I do not remember what you're supposed to with the "= [Number]" but I do believe you're supposed to sum the left and the right. So I do believe it's 8, now than remember this is not an exact answer, due to not knowing what it's properly to be.

Answer:

  (2³ +7)·8÷4 = 30

Step-by-step explanation:

You want to add parentheses to make a true statement from ...

  2³ +7·8÷4 = 30

We recognize that 2³ +7 = 15 and 8÷4 = 2, and the product of these is 30. So, we need to insert parentheses to make (2³ +7) be evaluated before multiplying by 8 and dividing by 4:

  (2³ +7) · 8 ÷ 4 = 30

Answer:

  416 in²

Step-by-step explanation:

You want the surface area of an isosceles triangular prism of length 10 in that has a triangular base with a base of 12 in and a height of 8 in.

The area of the prism is the sum of the areas a of the two triangular bases and the three rectangular faces.

The triangle area is given by ...

  A = 1/2bh

Then the area of the two identical triangles is ...

  A = bh = (12 in)(8 in) = 96 in²

The area of the three rectangular faces is ...

  A = ∑LW = (12 in)(10 in) +(10 in)(10 in) +(10 in)(10 in) = (12 +10 +10)(10) in²

  A = 320 in²

So, the total area is ...

  surface area = base area + face area

  surface area = 96 in² +320 in² = 416 in²

The surface area is 416 square inches.

The volume of this rectangular prism is equal to: B. 8 in³.

In Mathematics and Geometry, the volume of a rectangular prism can be calculated by using the following formula:

Volume of a rectangular prism = L × W × H

Where:

Since this rectangular prism is filled with 16 cubes and each cube is a 1/2 inch cube, the dimensions of the rectangular prism is given by;

Dimensions = 16 × (1/2)³ = 2inches.

By substituting the given dimensions (parameters) into the formula for the volume of a rectangular prism, we have the following;

Volume of rectangular prism = 2 × 2 ×  2

Volume of rectangular prism = 8 cubic inches.

Step-by-step explanation:

During the exponential phase, e.coli bacteria in a culture increase in number at a rate proportional to the current population. If growth rate is 1.9% per minute and the current population is 172.0 million, the population 7.2 minutes from now can be calculated using the following formula:

P(t) = P ₀e^(rt)where ,P₀ = initial population r = growth rate (as a decimal) andt = time (in minutes)Substituting the given values, P₀ = 172.0 million r = 1.9% per minute = 0.019 per minute (as a decimal)t = 7.2 minutes

The population after 7.2 minutes will be:P(7.2) = 172.0 million * e^(0.019*7.2)≈ 234.0 million (rounded to the nearest tenth)Therefore, the population of e.coli bacteria 7.2 minutes from now will be approximately 234.0 million.

Answer:

Volume of cone = 72 ft³

Step-by-step explanation:

diameter = 6ft

radius = 3ft

height = 8ft

Volume of a cone = \(\frac{\pi r^2h}{3}\)

V = (3 × 3 × 3 × 8)/3

V = 72 ft³

Answer:

V ≈  72 ft³

Step-by-step explanation:

Given that volume (V) is calculated using

V = \(\frac{\pi r^2h}{3}\) ( r is the base radius and h the height )

Here diameter d = 6 then r = 6 ÷ 2 = 3 and h = 8 , then

V = \(\frac{3(3^2)(8)}{3}\) ( cancel 3 on numerator/ denominator )

   = 9 × 8

   = 72 ft³

Step-by-step explanation:

I'm assuming this is asking for 3 separate fractions that are each equal to 2/3

Remember, multiplying the top and bottom of a fraction by a number will not change the fraction.

\(\frac{2}{3} *\frac{2}{2} =\frac{4}{6}\)

\(\frac{2}{3} *\frac{3}{3} =\frac{6}{9}\)

The solution to the system of inequalities in interval notation is [-2, 1].

Based on the information provided in the image below, we have the following system of inequalities;

-12 < 3x - 6

-3 ≥ 3x - 6

By adding 6 to both sides of the equation (inequality), we have;

-12 < 3x - 6

-12 + 6 < 3x - 6 + 6

-6 < 3x

-2 < x

x > -2 (flip)

-3 ≥ 3x - 6

-3 + 6 ≥ 3x - 6 + 6

3 ≥ 3x

1 ≥ x

x ≤ 1

Therefore, the solution to the system of inequalities is given by:

-2 < x ≤ 1
