B… I think…

Step-by-step explanation:

I think it's B because all the other ones increase at a constant rate, whereas B just squares x to get y.

Answer:

Since one of the angles is 90°, the triangle is right.

Step-by-step explanation:

Angles in a Triangle

The sum of angles in a triangle is 180°. We are given the angles are x, 5x, and 6x, thus:

x + 5x + 6x = 180

Simplifying:

12x = 180

Dividing by 12:

x = 180/12 = 15

x = 15°

5x = 75°

6x = 90°

Since one of the angles is 90°, the triangle is right.

18 divided into 7 would be 2 4/7... You would need three more astronauts to fill a third shuttle.

For your question: "The path of a seat on a new Ferris wheel is modeled by: What is the maximum height a rider will experience?"

The answer is B. 55 feet.

I got this through working this on my own. Let me know if you have any other questions down below.

The path of a seat on a new Ferris wheel is modeled by the function. the maximum height a rider will experience is 55 feet.

To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.

Putting those values of x in the second rate of function,

if results in negative output, then at that point, there is maxima.

If the output is positive then its minima and if its 0, then we will have to find the third derivative (if it exists) and so on.

The path of a seat on a new Ferris wheel is modeled by

[tex]x = -25sin( \dfrac{ \pi} {30}t)\\\\y= -25cos( \dfrac{ \pi} {30}t)+ 30,[/tex]

To find its maximum, we will derivate this function and equalize it to 0.

[tex]y'(t)= \dfrac{5}{6}\pi cos( \dfrac{ \pi} {30}t)\\\\y''(t)= \dfrac{1}{36}\pi^2 cos( \dfrac{ \pi} {30}t)[/tex]

Now given that we have an arbitrary critical point,

If   [tex]y''(t) > 0[/tex] then we will have a minimum at tn.

If  [tex]y''(t) < 0[/tex] then we will have a maximum at tn.

by replacing the equation with the critical points.

y(30) = 55

y(-30) = 55

We found out that the maximum height a rider will experience is 55 feet.

The answer is B. 55 feet.

Answer:

no

Step-by-step explanation:

A ratio can be written as a fraction:

7:6 can be written as 7/6, and 17:12 can be written as 17/12.

Now multiply the numerator and denominator of 7/6 by 2 to get an equivalent fraction and ratio: 14/12

14/12 is not equal to 17/12, so

7:6 and 17:12 are not equivalent

Answer: no

Answer:

x=21/40

Step-by-step explanation:

First get common denominators

3/8 *5 to top and bottom is now 15/40

3/20 *2 to top and bottom is now 6/40

isolate the X

x-15/40=6/40

+15/40    +15/40

x=21/40

Answer:

x = [tex]\frac{21}{40}[/tex]

Step-by-step explanation:

Given

x - [tex]\frac{3}{8}[/tex] = [tex]\frac{3}{20}[/tex]

Multiply through by 40 ( the LCM of 8 and 20 ) to clear the fractions

40x - 15 = 6 ( add 15 to both sides )

40x = 21 ( divide both sides by 40 )

x = [tex]\frac{21}{40}[/tex]

The slope of a graph is base on the rise over run of the line connected by the points which composed of an X and Y coordinate. The rise of the line is its Y and the Run is X. Base on the assigning of variables of its x and y value, the slope is calculate by dividing the weeks by its test so the answer is 3 over 4 or 0.75

Answer:

The answer is 5 m + 37 = 79.50

Step-by-step explanation:

You want to multiply 5 and m because m represents the amount he makes each hour and he works 5 hours each Wednesday. Then you add that to 37 to get $79.50.

Answer:

5 m + 37 = 79.50

Step-by-step explanation:

Answer:

flour $42 , bag of sugar $58

Step-by-step explanation:

let f represent flour and s represent sugar, then

7f + 5s = 584 → (1)

5f + 3s = 384 → (2)

Multiplying (1) by 3 and (2) by - 5 and adding will eliminate s

21f + 15s = 1752 → (3)

- 25f - 15s = - 1920 → (4)

Add (3) and (4) term by term to eliminate s , that is

- 4f = - 168 ( divide both sides by - 4 )

f = 42

Substitute f = 42 into either of the 2 equations and solve for s

Substituting into (1)

7(42) + 5s = 584

294 + 5s = 584 ( subtract 294 from both sides )

5s = 290 ( divide both sides by 5 )

s = 58

The cost of a bag of flour is $42 and cost of sugar is $58

Answer:

True

Answer:

The perimeter of the rectangle is 70 cm

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ Two sides of a rectangle are in the ratio 3 : 4

→ Let the width is the shorter side and the length is the longer side

∴ The ratio between the width and the length is 3 : 4

∵ The longer side is 20 cm

∴ The length of the rectangle = 20 cm

→ By using the ratio method

→  width  :  length

→  3          :  4

→  w         :  20

→ By using cross multiplication

∵ w × 4 = 3 × 20

∴ 4w = 60

→ Divide both sides by 4

∴ w = 15

∴ The width of the rectangle = 15 cm

∵ The perimeter of the rectangle = 2(length + width)

∴ The perimeter of the rectangle = 2(20 + 15)

∴ The perimeter of the rectangle = 2(35)

∴ The perimeter of the rectangle = 70 cm

∴ The perimeter of the rectangle is 70 cm

Answer:

[tex]x^{\frac{1}{3}}\:\times \left(x^{\frac{1}{2}}\:+\:2x^2\right)=x^{\frac{5}{6}}+2x^{\frac{7}{3}}[/tex]

Step-by-step explanation:

[tex]x^{\frac{1}{3}}\:\times \left(x^{\frac{1}{2}}\:+\:2x^2\right)[/tex]

Let us simplify the expression

[tex]x^{\frac{1}{3}}\:\times \left(x^{\frac{1}{2}}\:+\:2x^2\right)[/tex]

[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac[/tex]

[tex]a=x^{\frac{1}{3}},\:b=x^{\frac{1}{2}},\:c=2x^2[/tex]

so

[tex]=x^{\frac{1}{3}}x^{\frac{1}{2}}+x^{\frac{1}{3}}\times \:2x^2[/tex]

[tex]=x^{\frac{1}{3}}x^{\frac{1}{2}}+2x^2x^{\frac{1}{3}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

so the expression becomes

[tex]=x^{\frac{5}{6}}+2x^{\frac{7}{3}}[/tex]

Thus,

[tex]x^{\frac{1}{3}}\:\times \left(x^{\frac{1}{2}}\:+\:2x^2\right)=x^{\frac{5}{6}}+2x^{\frac{7}{3}}[/tex]
