Mathematics
1 answer:
balu736 [363]2 years ago
7 0

Answer:

4.11

Step-by-step explanation:

7(p-9)=-34.3

first you want to apply what is outside of the parenthesis to the inside of the parenthesis. After applying you would get

7p-63=34.3

Next you wanna get the variable to one side and the whole numbers to the other side. to do this you add 63 to each side, you end up with

7p=28.8. Then you want to get p by itself. In order for this to happen you divide each side by 7 to get p=4.114285714

Calculate the perimeter of the composite figure. Round your answer to the nearest hundredth. Use 3.14 for $\pi$ .
Elena-2011 [213]

1. Perimeter is 3 + 3 +3 +4 +5 = 18 feet

 Area = 3*3 = 9, 1/2*3*4 = 6, 9 + 6 =15 square feet

2. perimeter = 2.5 +2.5+ 2.5+2.5+0.5+0.5 = 11 meters

  Area = 3*.5 = 1.5, 3*2=6,  6+1.5 = 7.5 square meters

3. perimeter = 3.14*2*3 = 18.84 +8 = 26.8 inches

  Area = 6*4 = 24 + 3.14*3^2 = 28.26 = 28.26 +24 = 52.3 inches  

4. surface area = 2*π*6*20+2*π*6^2= 980.2 yards

Volume = π*6^2*20 = 2261.9 cubic yards

5.surface area = 2*(9*7+2*2+2*9) = 190 cm

Volume = 2*7*9 = 126 cubic cm

6. surface area = 2*(11*11+11*11+11*11) = 726 mm

 Volume = 11 *11*11 = 1331 cubic cm

Find the equation of the exponential function represented by the table below:
Elden [556K]

Answer:

The equation of the exponential function represented by the table will be:

f(x)= 2(4)^{x}

Step-by-step explanation:

We know the equation of exponential function such as

f(x) = ab^{x}

Put x=0, and y=2 in the function

2 = ab^{0}

2 = a

Also x=1, and y=8 in the function

8 = 2b^{1}

b=4

Thus,

f(x) = ab^{x}

        = 2(4)^{x}

Therefore, the equation of the exponential function represented by the table will be:

f(x)= 2(4)^{x}
