. A triangular prism is attached to a rectangular prism as shown below.If w = 8 inches, x = 5 inches, y = 20 inches, and z = 11.3 inches, what is the surface area of the figure?
a 860 square inches
b 760 square inches
c 960 square inches
d 1,060 square inches

Answers

Answer 1

Answer: i got u
5*5*2 for both sides of squares =50
8*8/2*2 for both sides of right triangles =64
8*20*2 for roof portion= 320
20*5*3 for walls and floor of house shape =300
z-x*y for space under roof and above walls
6.3*20=126
50+64+320+300+126=860 your answer is A
plz give brainliest -J (:

CANT GET WRONGJason is training for a marathon bike ride. His average speed increased from 3 miles per hour to 6 miles per hour in 3 months. Find the rate of change in the miles per hour that Jason bikes. A) .5 mile per hour per month B) 1 mile per hour per month C) 2 miles per hour per month D) 3 miles per hour per month

Answers

Answer: The correct option is (B) 1 mile per hour per month.

Step-by-step explanation: Given that Jason is training for a marathon bike ride. His average speed increased from 3 miles per hour to 6 miles per hour in 3 months.

We are to find the rate of change in the miles per hour that Jason bikes.

We know that

the average rate of change between the points (a, b) and (c, d) is given by

$A_r=(d-b)/(c-a).$

Since the number of months vary from 0 to 3, and the speed increases from 3 miles per hour to 6 miles per hour,

so the two points on the co-ordinate plane with number of months plotted across X-axis and average speed plotted on Y-axis are (0, 3) and (3, 6).

Therefore, the average rate of change in the miles per hour that Jason bikes is

$A_r=(6-3)/(3-1)=(3)/(3)=1.$

Thus, the required rate of change is 1 mile per hour per month.

Option (B) is correct.

B.... 6-3=3miles in 3 months .. and that's a mile per month

IMPORTANT PLEASE I NEED NOW:Find the area of each face of the cube whose volume is 729 cm

Answers

Answer:

Step-by-step explanation:

square root of 729= 9

9×9=81

Answer:

Step-by-step explanation:

Formula of Volume= $a^(3)$ - a = side

Therefore since the volume is given you just need to find the side.

729= $a^(3)$ = $\sqrt[3]{729}$ = a

= 9 = a

Now you know that 9 is the side, so using that find the area of one face-

Area of a square= 9 x 9 = 81 $cm^(2)$

Let f(x) = 16x5 – 48x4 – 8x3 and g(x) = 8x2. Find f of x over g of x. a) 2x2 + 6x + 1 b)2x2 – 6x – 1 c)2x3 + 6x2 + x d)2x3 – 6x2 – x

Answers

The answer is d)2x3 – 6x2 – x.

It is given:
$f(x)=16 x^(5)-48 x^(4) -8 x^(3)$
$g(x)=8 x^(2)$

We should find:
$f( (f(x))/(g(x)) )$

So, we just need to replace it in the equation:
$f( (f(x))/(g(x)) )= (16 x^(5)-48 x^(4) -8 x^(3))/(8 x^(2))$

Let's now separate each member of equation:
$f( (f(x))/(g(x)) )= (16 x^(5))/(8 x^(2)) - (48 x^(4))/(8 x^(2)) - (8 x^(3))/(8 x^(2)) = (16)/(8) x^(5-2) -(48)/(8) x^(4-2) -(8)/(8) x^(3-2)$

$f( (f(x))/(g(x)) )=2 x^(3) -6 x^(2) -x$

Answer:

$\boxed{\boxed{(f(x))/(g(x))=2x^3-6x^2-x}}$
