A ramp leads up to a building. The top of the ramp is 5 feet above the ground, and the bottom is 15 feet from the building as sh

kirill [66]

To answer this you have to use Pythagoras's theorem: a^2 + b^2 = c^2

Put in the values:
5^2 + 15^2 = c^2

Simplify it:
25 + 225 = c^2

Simplify again:
250 = c^2

Square root both sides:
15.8113883008 = c

So the ramp is:
15.8113883008 feet

Now round the number:
15.8ft

The above is the answer :)

Evaluate the expression for a = 5, b = 11, and c = 3. 2a + 2c(b − 5) A. 64 B. 46 C. 54 D. 163

Artemon [7]

2a +2c(b-5)

substitute a=5 b=11 c=3

2(5) +2(3) (11-5)

10+6(6)

Which graph shows the same end behavior as the graph of f(x) = 2x6 - 2x2 - 5?

aleksandrvk [35]

Step-by-step explanation:

End behavior of a polynomial function is the behavior of the graph of f(x) as x tends towards infinity in the positive or negative sense.

Given function:

f(x) = 2x⁶ - 2x² - 5

To find the end behavior of a function:

Find the degree of the function. it is the highest power of the variable.

Here the highest power is 6

Find the value of the leading coefficient. It is the number before the variable with the highest power.

Here it is +2

We observe that the degree of the function is even

Also the leading coefficient is positive.

For even degree and positive leading coefficient, the end behavior of a graph is:

x → ∞ , f(x) = +∞

x → -∞ , f(x) = +∞

The graph is similar to the attached image

10(x+1) = 56 - 2(x-1) what’s the equation

bixtya [17]

Answer:x=4

Step-by-step explanation:

To solve

10(x+1)=56-2(x-1)

Open the brackets

10x+10=56-2x+2

Collect like terms

10x+2x=56-10+2

12x=48

Divide through by 12

x=4

dexar [7]

Answer:

ok so we can turn both of these into equations

Bob: 112.96 divided by 138=0.81855072463

so about 82 cents per mile

Carl: 142.78 divided by 209=0.68315789473

so about 68 cents per mile

so ya i am a little confused but heres what i got
