Calculate the average velocity or a race car when an object travels on track and passes the 300m mark at 10 seconds and the 1100m mark at 24.5 seconds. rounded to the nearest whole number.

Answers

Answer:

55 m/s

Step-by-step explanation:

average velocity $=(1100-300)/(24.5-10) =(800)/(14.5)=(1600)/(29) \approx 55 ~m/s$

Find the slope of the line graphed below.

Answers

Answer:

The answer to your question is $m = - (4)/(7)$

Step-by-step explanation:

Process

1.- Find two points of the line (red points)

A ( 4, -5) and B (- 3 , -1)

2.- Find the slope using the formula

$m = (y2 - y1)/(x2 - x1)$

Substitution

$m = (-1 + 5)/(-3 - 4)$

$m = - (4)/(7)$

Find z if X=27, μ=20, and α=3.4. Round to the nearest hundredth if necessary.A. 2.06

B. –2.06

C. 1.18

D. 0.35

Answers

Answer:

A. $Z=2.06$

Step-by-step explanation:

We want to find the Z-score of $X=27$ if the population mean is $\mu=20$ ,and the population standard deviation is $\sigma=3.4$ .

We use the formula:

$Z=(X-\mu)/(\sigma)$

We substitute the values to obtain:

$Z=(27-20)/(3.4)$

$Z=(7)/(3.4)$

$Z=2.06$

The correct answer is A.

A cube has side length x. One side of the cube is increased by 4 inches, and another side is doubled. The volume of the new rectangular prism is 450 cubic inches. The equation 2x3 + 8x2 = 450 can be used to find x. What was the side length of the original cube? Use a graphing calculator and a system of equations to find the answer.4 inches
5 inches
9 inches
10 inches

Answers

The length of the side of the original cube in the given scenario is 5 inches.

A cube is a three-dimensional figure with equal sides.

Given that

The length of the edge of a cube = x

Also, one of the sides is increased by 4 inches, and another side is doubled,

so, now the new dimensions are x, x+4, 2x, and the shape is a rectangular prism.

The area of the rectangular prism = 450 sq. inches

base × height × length = 450 sq. inches

x × (x + 4) × 2x = 450

2x³ + 8x² = 450

2x³ + 8x² - 450 = 0

x³ + 4x² - 225 = 0

Substitute x=5 to see that it is a root of the equation,

5³ + 4(5)² - 225 = 125 + 100 - 225 = 0

So, x - 5 is a factor of the equation,

Now,

x³ + 4x² - 225 = (x−5)(x² + 9x + 45) = 0

The roots of the quadratic equation are imaginary as

D = 9² - 4 × 1 × 45 = 81 - 180 = -99

The discriminant is negative, therefore, the roots are not real.

So, the length of the side of the original cube is 5 inches.
