Answer:

Option (D) is true.

Step-by-step explanation:

Given the equation

25x⁴ - 625y - 500 = 0

solving in terms of y as a function of x

[tex]25x^4\:-\:625y\:-\:500\:=\:0[/tex]

Step 1: Add -25x⁴ to both sides

[tex]25x^4\:-\:625y\:-\:500\:+\:\left(-25x^4\right)=0+\left(-25x^4\right)[/tex]

[tex]-625y-500=-25x^4[/tex]

Step 2: Add 500 to both sides

[tex]-625y-500\:+500=-25x^4\:+500[/tex]

[tex]-625y=-25x^4\:+500[/tex]

Step 3: Divide both sides by -625

[tex]\frac{-625y}{-625}=\frac{\left(-25x^4\:+500\right)}{-625}[/tex]

[tex]\:\:y=\:\frac{1}{25}x^4-\frac{4}{5}[/tex]

Therefore,

[tex]\:f\left(x\right)=\:\frac{1}{25}x^4-\frac{4}{5}[/tex]

Thus, option (D) is true.

Answer: the smallest initial velocity that is required to throw the stone is 56 ft/s

Step-by-step explanation:

We know that;

u = initial velocity  

v = final velocity  = 0

a = acceleration  = -g = -32,

s = distance travelled  = 49 feet

V² - u² = 2aS

we substitute

0² - u² = 2 × -32 × 49

0 - u² = -3136

u² = 3136

u = √3136

u = 56 ft/s

Therefore the smallest initial velocity that is required to throw the stone is 56 ft/s

Step-by-step explanation:

From the question, we are informed that the ratio of beans to rice at T.Blancos place is 2 to 3 and that there are 27 grains answer of rice on the plate. The number of beans would be:

= 2/3 × 27

= 18.

Therefore, the total number of beans and rice on the plate will be:

= 27 + 18

= 45

Answer:

Step-by-step explanation:

T=16d=135

The linear equation in  slope-intercept form to find Ethan's total weekly pay is T = 16d + 135

A linear equation is in the form:

y = mx + b

where m is the slope of the line, b is the y intercept and y, x are variables.

Let T represent the total money paid to Ethan in a week for d deliveries.

Ethan is paid $16 per delivery, hence m = 16.

T = 16d + b

For 5 deliveries, his total pay was $215. Hence when d = 5, T = 215:

215 = 16(5) + b

215 = 80 + b

b = 135

T = 16d + 135

The linear equation in  slope-intercept form to find Ethan's total weekly pay is T = 16d + 135

Step-by-step explanation:

Answer:

40°, 60°, and 80°

Step-by-step explanation:

We know that the sum of the angles of a triangle is equal to 180°.

We can use this equation to solve for these angles:

180 = 2x + 3x + 4x

180 = 9x

20 = x

Then substitute the solution in for x to solve for the angles:

2(20) = 40°

3(20) = 60°

4(20) = 80°

Therefore, the angles are 40°, 60°, and 80°.

Step-by-step explanation:

The formula that gives the x-coordinates of the maximum values of

y = cos(x) is kπ for k= 0, 2±, ±4.

Option B is the correct answer.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

The formula that gives the x-coordinates of the maximum values for

y = cos(x) is kπ + π/2 or (2k+1)π/2, where k is any integer.

Now,

This formula corresponds to kπ for k= 0, 2±, ±4

where k can take the values 0, 2, -2, 4, -4, etc.

The cosine function oscillates between -1 and 1, with a period of 2π.

The maximum value of the function is 1, which occurs when the argument of the cosine function is an odd multiple of π/2.

This means that the x-coordinates of the maximum values are given by:

x = kπ + π/2, where k is any odd integer

We can simplify this formula by writing k = 2m+1, where m is any integer, to obtain:

x = (2m+1)π/2

This formula covers all the possible values of k, including positive and negative integers.

For example, when m = 0, we get x = π/2, which is the first maximum value of the function.

When m = 1, we get x = 3π/2, which is the second maximum value, and so on. If we allow m to be negative, we get the values of x for the maximum values of the cosine function in the negative direction.

Therefore,

kπ for k= 0, 2±, ±4

which gives the values of k that correspond to the x-coordinates of the maximum values of y = cos(x).

Answer: 22 ft²

Step-by-step explanation:

To find the area of a rectangle, we multiply the length and width. It doesn't matter which is which as we get the same answer in the end.

Given information:

Length = 11 ft

Width = 2 ft

Area = length x width

Area = 11 ft x 2 ft = 22 ft²

You'll notice the unit is feet squared or ft², because feet x feet gives us feet².

Answer:

Simple, no. This would not be enough.

Step-by-step explanation:

This is because you mentioned that there are 20 students and each of them needed 2 plates. So, there would need to be at least 40 plates. Forks seem irrelevant in this question but if the teacher has 8 plates in 1 box and another 8 in the second box, that would sum up to 16 plates that are available. And the fact that the box doesn't even include the other items, should hint the lack of items available for the students.

This question seemed worded differently. But tried my best. :)

Answer:

3.68 inches × 77.28 inches

Step-by-step explanation:

Given that,

The perimeter of a rectangle is 162 inches.

Let the width is b.

ATQ,

Length = 7 times than 3 times the width

l = 7(3b) = 21b ...(1)

The perimeter of a rectangle is given by :

P = 2(l+b)

Put all the values,

162 = 2(21b+b)

81 = 22b

b = 3.68 inches

Put the value of b in equation (1)

l = 21b

= 21 (3.68)

= 77.28 inches

Hence, the dimensions of the rectangle are 3.68 inches × 77.28 inches

To solve this problem, we can simply use the formula of normal distribution and substitute the values where required.

The value of P(x <= 44) is 0.025 which is option D

Given the value of the mean, normal distribution and standard deviation, we can calculate where the value lies

Data;

But we know that

[tex]z = \frac{x- \mu}{\sigma}[/tex]

Let's substitute the values of x, standard deviation and mean into the equation above

[tex]z = \frac{x-\mu}{\sigma} \\z = \frac{44-50}{3} =-2[/tex]

Solving this further;

[tex]P(z\leq -2) = \frac{1}{2} - \frac{1}{2}(0.9545)\\p(z\leq -2) = 0.025[/tex]

Step-by-step explanation:

the percent proportion is a/w = p/100

where A is a part of the whole W, and p% or p/100 is the percent

a/140 = 15/100 (Substitute w =140 and p= 15)

a times 100=140 times 15 (cross poducts property)

100a=2100  (Multiply)

Answer:

Please check the explanation.

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get the equation

y ∝ x

y = kx

k = y/x

Here k is called the constant of proportionality.

Taking an example:

For example, let suppose x and y are directly proportional with x = 4 and y = 10.

We can calculate the constant of proportionality using the formula

k = y/x

substitute x = 4, y = 10 in the equation

k = 10/4

k = 2.5

And at x = 5 and y = 12.5

k = y/x

substitute x = 5, y = 12.5 in the equation

k = 12.5/5

k = 2.5

Therefore, we conclude that a constant of proportionality k = 2.5.
