Steve props a ladder against a wall of a building so that the he can get to the roof and
throw water balloons at pedestrians. If the angle of elevation from the bottom of the
Aladder to the roof is 60°, and the building is 35 feet tall, how long must the ladder be
to the nearest tenth of a foot?

Answer:

If the function is reflected across the x-axis, the negative sign will be like this -f(x)

If the function is reflected across the y-axis,  it will be lie this f(-x)

Translation is the movement of an object without any change of size, whereas change of slope is the difference in steepness.  

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

In function notation, f(x) equals the y value and the x equals the x value. So this question is asking you to find the value of y when x=-2. To do this find -2 on the graph and find the point with the same x value, then find what value of y it is on. In this case, f(-2)=2.

Answer:

she charges 20 dollars per photo

for every photo it goes up by 20. you could say that the slope is 20 also.

Answer:

She charges 20 dollars per photo

Step-by-step explanation:

Pick any price on the y axis and divide by the corresponding x-value. For example, the line has a point at (60,3) so we can divide 60 by 3 to give us 20. 20 is therefore the slope of the line.

Answer:

A: 35

Step-by-step explanation:

DG is the combined segments DO and OG. In other words:

[tex]DG=DO+OG[/tex]

We know that DG is 60. DO is (4x-3) and OG is (2x+21). So, substitute:

[tex]60=(4x-3)+(2x+21)[/tex]

Solve for x. Combine like terms:

[tex]60=6x+18[/tex]

Subtract 18 from both sides:

[tex]42=6x[/tex]

Divide both sides by 6. Hence, the value of x is:

[tex]x=7[/tex]

GO is defined as (2x+21).

So, to find GO, we can now substitute 7 for x and evaluate. Therefore:

[tex]GO=2(7)+21=14+21=35[/tex]

Hence, our answer is A.

Answer:

23

Step-by-step explanation:

First, we can rearrange the equation to make it look simpler.

2+y+11 ---->

y+2+11

Then, we can combine like terms, thus

y+13

Then, we can plug in 10 for y

(10)+13

Combine like terms again, and the answer is:

23

In the interval 0 ≤ x ≤ 4 the height of the ball increase and then decrease option (A) is correct.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

It is given that:

The ball was thrown up into the air and allowed to bounce until it came to a halt.

As we know,

The parabola can be defined as the graph of a quadratic function that has something bowl-shaped.

(x - h)² = 4a(y - k)

(h, k) is the vertex of the :

a = √[(c-h)² + (d-k²]

(c, d) is the focus of the parabola:

Thus, in the interval 0 ≤ x ≤ 4 the height of the ball increase and then decrease option (A) is correct.

Answer:

Less Than :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

I'm not entirely sure what the question is, but I suspect the answer is not prime.

9x^2 - 4

factors into two factors  (3x + 2)(3x - 2)

Suppose x = 11 which is prime.

9*121 - 4

1085 which ends in a 5 so the expression is not prime.

In fact, the two factors are 3*11 + 2 = 35  and 3*11 - 2 = 31

31*35 = 1085

Answer:

  F.  (3x +2)(3x -2)

Step-by-step explanation:

The given expression is the difference of two squares, so can be factored accordingly.

  9x^2 -4 = (3x)^2 -2^2 = (3x +2)(3x -2) . . . . . matches F

Answer:

The answer would be x=4.  

Step-by-step explanation: Step 1: Simplify both sides of the equation.

2x+3(5x−7)=47

2x+(3)(5x)+(3)(−7)=47(Distribute)

2x+15x+−21=47

(2x+15x)+(−21)=47(Combine Like Terms)

17x+−21=47

17x−21=47

Step 2: Add 21 to both sides.

17x−21+21=47+21

17x=68

Step 3: Divide both sides by 17.

17x/17=68

17x=68

Step-by-step explanation:

3x + 6 = 36 - 3x

6x = 30

x = 5

Answer:

-$13.5

Step-by-step explanation:

Let x be a random variable of a count of player gain.

- We are told that if the die shows 3, the player wins $45.

- there is a charge of $9 to play the game

If he wins, he gains; 45 - 9 = $36

If he looses, he has a net gain which is a loss = -$9

Thus, the x-values are; (36, -9)

Probability of getting a 3 which is a win is P(X) = 1/6 since there are 6 numbers on the dice and probability of getting any other number is P(X) = 5/6

Thus;

E(X) = Σ(x•P(X)) = (1/6)(36) + (5/6)(-9)

E(X) = (1/6)(36 - (5 × 9))

E(X) = (1/6)(36 - 45)

E(X) = -9/6 = -3/2

E(X) = -3/2

This represents -3/2 of $9 = -(3/2) × 9 = - 27/2 = -$13.5

Answer:

89

Step-by-step explanation:

We know that all the inside angles of a triangle summed up is 180 so we just do 68 + 23 which is 91 now we use 180 and subtract 91 from it, 180-91 which equals 89

Using the slope formula, you can form this equation! The slope of any equation would replace the m, and the y intercept would replace b!

I added in the slope formula at the bottom, just in case, so you'll see what I mean!
