what is this have no clue of how to do it ? ? n+31.53 =62.4 and this one to 9.2+n+8.4=20.8 please help !

mihalych1998 [28]

Ok so to solve to first one u do this:

62.4 - 31.53, which gives u 30.87. and then u add 30.87 and 31.33, and u get 62.4

for the second one u do the same thing.

The graph of f is given in the figure to the right. Let A(x)equals=Integral from 0 to x f left parenthesis t right parenthesis

Tpy6a [65]

Answer:

$A(4)=-4\pi$

$A(8)=-4\pi +8$

$A(12)=-4\pi +16$

$A(14)=-4\pi +15$

Step-by-step explanation:

we are given

$A(x)=\int\limits^x_0 f{x} \, dx$

Calculation of A(4):

we can plug x=4

$A(4)=\int\limits^4_0 f{x} \, dx$

Since, this curve is below x-axis

so, the value of integral must be negative

and it is quarter of circle

so, we can find area of quarter circle

radius =4

$A(4)=-\frac{1}{4}\times \pi \times (4)^2$

$A(4)=-4\pi$

Calculation of A(8):

we can plug x=8

$A(8)=\int\limits^8_0 f{x} \, dx$

we can break into two parts

$A(8)=\int\limits^4_0 f{x} \, dx+\int\limits^8_4 f{x} \, dx$

now, we can find area and then combine them

$A(8)=-4\pi +\frac{1}{2}\times 4\times 4$

$A(8)=-4\pi +8$

Calculation of A(12):

we can plug x=12

$A(12)=\int\limits^12_0 f{x} \, dx$

we can break into two parts

$A(12)=\int\limits^4_0 f{x} \, dx+\int\limits^8_4 f{x} \, dx+\int\limits^12_8 f{x} \, dx$

now, we can find area and then combine them

$A(12)=-4\pi +\frac{1}{2}\times 8\times 4$

$A(12)=-4\pi +16$

Calculation of A(14):

we can plug x=14

$A(14)=\int\limits^14_0 f{x} \, dx$

we can break into two parts

$A(14)=\int\limits^4_0 f{x} \, dx+\int\limits^8_4 f{x} \, dx+\int\limits^12_8 f{x} \, dx+\int\limits^14_12 f{x} \, dx$

now, we can find area and then combine them

$A(14)=-4\pi +\frac{1}{2}\times 8\times 4-\frac{1}{2}\times 1\times 2$

$A(14)=-4\pi +16-1$

$A(14)=-4\pi +15$

Which statements are TRUE? Select all that apply.

musickatia [10]

Answer:

A, B, D are true

Step-by-step explanation:

A) Speed = Distance travelled ÷ time taken

= 112 ÷ 1.75

= 64 miles per hour

True

B) Cost of 6 pens = $7.74

Cost of 1 pen = 7.74 ÷ 6 = $ 1.29

Cost of 7 pens = 1.29 * 7 = $ 9.03

TRUE

C) Speed = 57 miles per hour

4 hour 10 minutes = 250 minutes

Distance traveled in an hour = 57

Distance traveled in 250 minutes = (57* 250) ÷ 60 = 237.50 miles

FALSE

D) Cost of 17 cans = $ 38.59

Cost of 1 can = 38.59 ÷ 17 = $2.27

Cost of 3 cans = 2.27 * 3 = $ 6.81

TRUE

e) Cost of two dozen eggs = $ 8.40

Cost of an egg = 8.40 ÷ 24 = $ 0.35

FALSE
