Evaluate -x^2+4x+1 when x=-2

Answer:

$24

Step-by-step explanation:

Fist, you will multiply the percent, 15, and the total money amount, 160, which you would get 2,400. Then, divide 2,400 by 100, and there you will get the tip, $24. I hope this helps :)

Answer:

  C. 78°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

  (7x-6)° +(4x+11)° +43° = 180°

  11x +48 = 180 . . . . . divide by °, simplify

  11x = 132 . . . . . . . subtract 48

  x = 12 . . . . . . . divide by 11

Then the measure of angle T is ...

  ∠T = (7x -6)° = (7(12) -6)°

  ∠T = 78°

Answer:

48

Step-by-step explanation:

6+x/4 = 18

x/4 = 12

x= 48

Answer:

x = 48

here's your solution

=>. let the number be. X

=> now , quater of this number = X/4

=> then 6 is added to it

=> we get this. =. 6 + X/4

=> it is given that this number is equal to 18

=>. so, our final equation is 6 + X/4 = 18

=> solve , X/4 = 18 - 6

=> X/4 = 12

=>. X = 12*4

=> X = 48

hope it helps

Answer:

[tex]\Large \boxed{\sf A}[/tex]

Step-by-step explanation:

[tex]\displaystyle \left(\frac{2}{3}\right)^4[/tex]

n  → exponent, means to multiply the base number by itself n  no. of times.

Here we multiply the base number by itself 4 times.

[tex]\displaystyle \frac{2}{3}\cdot \frac{2}{3}\cdot \frac{2}{3}\cdot \frac{2}{3}[/tex]

Answer: A.

To expand a exponent, you'll find the number how much it powers by and expand it by what the power or exponent number represents.

The fraction is 2/3 and the exponent is 4. Like I've said before, to expand it you'll find the number how much it powers by.

In the equation, 2/3 is going to the 4th power, so we will expand the fraction 4 times.

2/3 × 2/3 × 2/3 × 2/3

is 2/3 to the 4th power in expanded form.

Hence, A is the answer.

explanation:

The surface area of the prism is 108 m².

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Given is the figure of a triangular prism.

Triangular prism consists of two triangular bases and three rectangular lateral faces.

Triangular base is right triangle.

Surface area of prism = area of bases + area of lateral faces

Area of a triangular base = [tex]\frac{1}{2}[/tex] × base × height

                                          = [tex]\frac{1}{2}[/tex] × 4 × 3

                                          = 6 m²

Area of two triangular bases = 2 × 6 = 12 m²

Area of a rectangle = length × width

Area of rectangular faces = (8 × 5) + (8 × 4) + (8 × 3)

                                           = 40 + 32 + 24

                                           = 96 m²

Total surface area = 12 m² + 96 m² = 108 m²

Hence the total surface area of the prism is 108 m².

Step-by-step explanation:

b because the angles of a trinagle are accurate for the cm. And because the angles of traingles are small.

The difference in length between the longest ski trail and the shortest ski trail is 7/4.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

Length of the longest ski trail = 3 1/8 = 25/8

Length of the shortest ski trail = 1 3/8 = 11/8

Difference in length between the longest ski trail and the shortest ski trail:

= 25/8 - 11/8

= 14/8

= 7/4

Thus, the difference in length between the longest ski trail and the shortest ski trail is 7/4.

Answer:

1)x=71     2) =137

Step-by-step explanation:

1) 180-32=148 you minus it from 180 because the angles on a straight line add up to 180

2x+6=148

2x=142

x=71

2) 180-39=141

x+4=141

x=137

Ok.

1. g(7) = 9

So, f(9) = 0

2. f(3) = 9

So, g(9) = 4

3. f(2) = 5

So, f(5) = 8

4. g(8) = 8

So, g(8) = 8

Done.

Answer:

Step-by-step explanation:

composite functions, but just think of it as one function.. that does it's thing and then feeds into another function...

so g(x) starts it.. and gets a 7 and outputs a 9

then f(x) gets the 9 from g(x) and outputs a  )

so f(g(7)) = 0

next f(x) gets a 3 and outputs a 9

then g(x) gets that 9 and outputs a 4

so g(f(3)) = 4

next f(x) gets a 2 and outputs a 5

then then next f(x) gets that 5 and outputs an 8

f(f(2) )  = 8

next g(x) gets an 8 and outputs an 8

the next g(x0 get that 8 and outputs another 8

kinda boring at 8 ... same ol same ol  :P

g(g(8)) = 8
