what's the angle of elevation from the bench to the top of this building?​

Answer:

f(-5)=5

Step-by-step explanation:

the "-5" is telling us what to plug in for x. So, the new equation would be:

f(-5)= -(-5)^2-7(-5)-5

if we reduce, the expression would be

-25+35-5

our final answer would be 5.

Answer:

[tex]c = 5[/tex]

Step-by-step explanation:

Given

[tex]f(c) = M[/tex]

[tex]f(x) = x^2 - x + 1[/tex]

[tex]Interval: [1,8][/tex]

[tex]M = 21[/tex]

Required

Find c using Intermediate Value theorem

First, check if the value of M is within the given range:

[tex]f(x) = x^2 - x + 1[/tex]

[tex]f(1) = 1^2 - 1 + 1[/tex]

[tex]f(1) = 1[/tex]

[tex]f(x) = 8^2 - 8 + 1[/tex]

[tex]f(x) = 57[/tex]

[tex]1 \le M \le 57[/tex]

[tex]1 \le 21 \le 57[/tex]

M is within range.

Solving further:

We have:

[tex]f(c) = f(x) = M[/tex]

[tex]f(x) = 21[/tex]

Substitute 21 for f(x) in [tex]f(x) = x^2 - x + 1[/tex]

[tex]21 = x^2 - x + 1[/tex]

Express as quadratic function

[tex]x^2 - x + 1 - 21 = 0[/tex]

[tex]x^2 - x - 20 = 0[/tex]

Expand

[tex]x^2 + 4x - 5x - 20[/tex]

[tex]x(x+4)-5(x+4)=0[/tex]

[tex](x - 5)(x+4) = 0[/tex]

[tex]x - 5 = 0[/tex] or [tex]x + 4= 0[/tex]

[tex]x = 5[/tex] or [tex]x = -4[/tex]

The value of [tex]x = -4[/tex] is outside the [tex]Interval: [1,8][/tex]

So:

[tex]x = 5[/tex]

[tex]f(c) = f(x) = M[/tex]

[tex]f(c) = f(5) = 21[/tex]

By comparison:

[tex]c = 5[/tex]

Answer:

using

h²=p²+b²

3is your answer

a²=5²-4²

a=√9=3

so you should write 8 in a box then under the box write what place it is like hundredth and you do the same for the rest

8                                       0               7           , 8              2           5

hundred thousandth^  and so on^

Total surface area:

Answer:

  88 square inches

Step-by-step explanation:

The figure can be divided into two congruent trapezoids, each with bases 7 and 4 inches, and height 8 inches. Then the total area is ...

  A = 2(1/2)(b1 +b2)h

  A = (7 +4)(8) = 88 . . . . square inches

Answer:

i got x= 16/165

Step-by-step explanation:

Answer:

A = (1/2)bh

Step-by-step explanation:

A = (.5)(21)(14)

Answer:

1. x=15

2. x=128

3. x=47

4. x=21

[tex](-8)*\frac{2}{3} = -\frac{16}{3}[/tex]

[tex](-8)*(-\frac{2}{3} ) = \frac{16}{3}[/tex]

[tex]-\frac{18}{3} = -6[/tex]

[tex]\frac{-18}{-3} = 6[/tex]

Answer:

Step-by-step explanation:

Answer: x=15

Step-by-step explanation:

Since these are supplementary angles, we know that if we add them together we would get 180 deg. so....

(7x-10)+ (6x-5)=180

Kay so now we can combine like terms.

13x-15=180

Now we can add 15 to both sides.

13x=195

Finally Divide 13 on both sides.

X would then now equal 15.

Answer:

118ft²

Step-by-step explanation:

good luck, i hope this helps :)

Answer:

900 miles

Step-by-step explanation:

In 7 days she travels 525 miles.

So, in 1 day she travels: 525 ÷ 7 = 75miles

In 12 days she will have driven : 75 × 12 = 900 miles

Step-by-step explanation:

of at 7days Jill drove 525 miles

then she would drive x Miles in 12 days

7d = 525 miles

12 d = (12 ×525)/7

900 miles
