Answer:

4.2 ft

Step-by-step explanation:

We can assume that the truck is vertically straight, so this will make up the vertical side of the triangle.

This means that the triangle is a right triangle since a right angle will be formed with the ground and the 3 ft side.

Next, we have the ramp length which is 5.2 ft long. This will be the hypotenuse of the right triangle since the ramp is slanted.

We want to find the length of the horizontal leg of the right triangle, which will give us the horizontal distance the ramp reaches.

We can use the Pythagorean Theorem since this is a right triangle:

Substitute these values into the equation and solve for b.

The horizontal distance the ramp reaches is 4.2 ft, parallel to the ground.

Given:

The function is:

[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]

To find:

The value of [tex]\dfrac{dy}{dx}[/tex].

Solution:

We have,

[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]

It can be written as

[tex]y=-\dfrac{3}{4}x^{\frac{5}{2}}[/tex]        [tex][\because \sqrt[n]x=x^\frac{1}{n}][/tex]

Differentiate with respect to x.

[tex]\dfrac{dy}{dx}=-\dfrac{3}{4}\times \dfrac{5}{2}x^{\frac{5}{2}-1}[/tex]       [tex][\because \dfrac{d}{dx}x^n=nx^{n-1}][/tex]

[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{5-2}{2}}[/tex]

[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{3}{2}}[/tex]

[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}\sqrt{x^3}[/tex]

Therefore, the value of [tex]\dfrac{dy}{dx}[/tex] is [tex]-\dfrac{15}{8}\sqrt{x^3}[/tex].

Step-by-step explanation:

let's figure out first the value of the angles from 0- 360 degrees

The question is incomplete:

Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels? The table that shows the types of bagels sold at the bagel shop on Friday is attached.

a. $70

b. $20

c. $90

d. $110

Answer:

c. $90

Step-by-step explanation:

First, you need to find the amount of bagels that Sasha purchased. The statement indicates that she buys all the chocolate chip bagels and the table shows that 28 chocolate chips bagels were sold, so that's the amount she purchased of this type of bagels. Also, the statement indicates that she buys half of the plain bagels and the table says that 16 plain bagels were sold, so you have to divide this amount by 2:

16/2=8

Then, you have to add the amount of chocolate chips bagels plus the amount of plain bagels that Sasha purchased:

28+8=36

Now that you know the amount of bagels that Sasha purchased, you have to multiply this for 2.50 that is the price per bagel:

36*2.50=90

According to this, the answer is that Sasha spends $90 on bagels.

Answer:

The answer is D) There are three proportional relationships

Step-by-step explanation:

The green line (the one in the middle) is a straight line through the origin. This is a proportional relationship.

Reason: It goes through 0,0

----------------------------------------------------------------------------------------------------------------

The blue line (the one at the top) is a straight line through the origin. This is a proportional relationship.

Reason: It goes through 0,0

----------------------------------------------------------------------------------------------------------------

The purple line (the one at the bottom) is a straight line through the origin. This is a proportional relationship.

Reason: It goes through 0,0

----------------------------------------------------------------------------------------------------------------

Conclusion: Since the blue, green, and purple lines are proportional, this means all 3 lines are proportional.

Answer:

1. 45

2. 33

Explanation:

1. 4x² + 6x - 9

= 4(9) + 18 - 9

= 36 + 18 - 9

= 45

2. 3y + 7(2y - 5)

= 12 + 7(8 - 5)

= 12 + 56 - 35

= 33

i hope this helps! :D

Answer:

45

33

Step-by-step explanation:

4(3)^2+6(3)-9= 36+18-9= 45

3(4)+7(2*4-5)= 12+7(8-5)= 12+7(3)= 33

Step-by-step explanation:

I hope this helps.

Answer:

B: 14/15

Step-by-step explanation:

Here's why I say this:

The total is 120. 8 have a box meaning 112 do not have a box. The question is asking about those without a box, so 112 will be used. 112/120. Simply by dividing each the numerator and denominator, in this case by 8. The fraction left is 14/15

Answer:

SSS or SAS

Step-by-step explanation:

Remark

Since the two diagonals bisect each other, you have created two sets of equal lines. If that is the case, then you could prove the equality of the triangles 2 different ways.

1) The angles at the center are vertically angles which makes them equal. Since they are equal, the triangles are congruent by SAS. Notice that the angle is between the 2 equal sides.

2) Since CD and AB are marked as being equal, the triangles are congurent by SSS.

Answer:

  f(x) = 3x³ +6x² -3x -6

Step-by-step explanation:

Each x-intercept (x=p) gives rise to a factor (x-p), so the factored form of the function is ...

  f(x) = a(x -(-2))(x -(-1))(x -1)

The value of 'a' is chosen to make the y-intercept match that shown. The function just written has ...

  f(0) = -6 = a(2)(1)(-1)

  -6 = -2a

  a = 3 . . . . . divide by -2

So, the function in factored form is ...

  f(x) = 3(x +2)(x +1)(x -1)

Expanded, this is ...

  f(x) = 3x³ +6x² -3x -6

Answer:

The quotient is negative.

Step-by-step explanation:

The rules of signs for multiplication and division of two numbers are the same.

If you multiply or divide two numbers with the same sign (both positive or both negative), the answer is positive.

If you multiply or divide two numbers with different signs (one positive and one negative), then the answer is negative.

Since the product is negative, then the quotient is also negative.

Answer: The quotient is negative.

Answer:

11

Step-by-step explanation:

16-x

substitute with 5

16-5

11

The value is 11.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Here, given that,

16-x

now, we have to ,

substitute with 5

=16-5

=11

Hence, The value is 11.
