Answer:B

y=13cos(1/13x)+13

Step-by-step explanation:

The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.

It is a function that repeats itself in a particular time interval.

You ride through some wet paint on your bike, creating a red spot on the tire.

Write a cosine equation to model the height of the red spot over the distance you ride.

Your bike tire has a radius (r) of 13 inches.

The period is the circumference of the tire (2πr).

The cosine equation is given as

y = A cos (Bx + C) + D

Where

A = the amplitude

B = time period

C = phase difference

D = shifting of central line

Then we have the diagram

A = 13

B = 1/13

C = 0

D = 13

Then the equation will be

[tex]\rm y = 13 \cos (\dfrac{1}{13}x - 0 ) + 13\\\\y = 13 \cos (\dfrac{x}{13} ) + 13[/tex]

Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Answer:

m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46

Step-by-step explanation:

-4m² + 2m - 11 = -5m²

m² + 2m - 11 = 0

m² + 2m + 1 = 12

(m + 1)² = 12

m + 1 = ± √12

m = -1 ± 2√3

First, the function was multiplied by 3, which is a vertical dialation by a factor of 3. Then, we subtracted 2 from the function, which is a vertical shift down two units. Therefore, the answer is C

The transformations are applied to the graph of the function should be option c. a vertical dilation by a factor of 3 and a vertical shift down 2 units

Since

First, the function should be multiplied by 3, that represent vertical dilation by a factor of 3. After this, we subtracted 2 from the function, i.e. is a vertical shift down two units.

Answer:

Solving steps

We know x= -10-15y, so we can subtract it to the equation above

x = -10-15y

2x+5y=35

2(-10-15y) + 5y = 35

(Refer to the 1st image to solve for y)

Y = -11/5

We now know y= -11/5, so we can subtract it to the equation for x.

Y = -11/5

x = -10-15y

x = -10-15(-11/5)

(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)

x = 33 - 10

x = 23

r = radius = 3m

h = height = 7m

V = (1/3)(π)(3m²)(7m) = 65.97m³

Answer:

C.

Step-by-step explanation:

The smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

The margin of error (E) for a confidence interval is described as:

E = z × (σ / √n)

where:

E is the desired margin of error

z is the z-score corresponding to the desired confidence level (in this case, 99% confidence level)

σ is the population standard deviation

n is the sample size

In this case, the margin of error is no more than ±1 inch, so E = 1 inch.

Now, determine the z-score corresponding to a 99% confidence level using a standard normal distribution table or statistical software.

For a 99% confidence level, the z-score is approximately 2.576.

Plugging in the known values into the margin of error formula,

1 = 2.576 × (2.4 / √n)

To solve for n, rearrange the formula as follows:

√n = (2.576 × 2.4) / 1

√n = 6.1824

n = (6.1824)²

n ≈ 38.16

Therefore, the smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

Answer:

4329 softballs

Step-by-step explanation:

To find the number of softballs that will fit into the container, we first find the volume of the softball. Since it is a sphere, its volume V = 4πr³/3 where r = radius = d/2 where d = diameter of softball.

So, V = 4π(d/2)³/3 = πd³/6

Since d = 8.3 in,

V =  πd³/6 =  π(8.3 in)³/6 = π × 571.787 in³/6 = 299.39 in³

The volume of the box, V' = 15 × 10 × 5 ft³ = 750 ft³ = 750 × (12 in)³ = 750 × 1,728 in³ = 1,296,000

So, for n softball to fit, its volume must equal the volume of the storage unit.

The volume of n softballs is nV.

For the softballs to fit, V' = nV

n = V'/V

= 1,296,000 in³/299.39 in³

= 4328.8 softballs

≅ 4329 softballs since we cannot have a decimal number of softballs.
