Determine if the data comes from a linear function or an exponential function. Then, enter

1 answer:

8 0

1. The data is not linear. There's not a constant difference between the f(x) values. (AKA there's not a fixed slope between the data points)

2. The data is exponential, because there's a consistent ratio in the f(x) values:

189/567 = 1/3

63/189 = 1/3

21/63 = 1/3

7/21 = 1/3

Each new y-value (aka f(x)-value) is 1/3 the previous value.

Also, f(0)=567.

If we put that together, we have f(x) = 567 (1/3)^x.

Maria works in a factory that produces new cars. She is having trouble with one of the machines. In order to work properly, the

Dovator [93]

Answer:

Maria did her job properly. Both gears are perpendicular.

Step-by-step explanation:

Recall that given vectors a and b, they are perpendicular if and only if $a\cdot b$ =0. If $a=(a_1,a_2),b=(b_1,b_2)$ . Then $a\cdot b = a_1b1_+a_2b_2$ .

IN our case a=(5,-1,2) and b) (1,-3,-4). So,

$a\cdot b = 5\cdot 1 + (-1)\cdot(-3) + 2\cdot(-4) = 5+3-8 =0$

So both gears are perpendicular.

The seniors on the student council bought a total of 36 plants to use in landscaping the front of the school. They bought some a

Artyom0805 [142]

Answer: B

Step-by-step explanation:

y = azaleas

x = lilies

6y + 5x =196 total cost

y + x = 36 total number of items

y = 36 – x

6(36 -x ) +5x =196

216 – 6x + 5x = 196

-x = 196 – 216

-x = -20

Divide by -1

X = 20 lilies

Plug into y equation

Y = 36 – 20

Y= 16 azaleas

To check

6(16) + 5(20) = 196

96 + 100 = 196

Help me answer this question

Roman55 [17]

Answer:

5 seconds

Step-by-step explanation:

When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...

h(t) = 96

96 +80t -16t^2 = 96

16t(5 -t) = 0 . . . . subtract 96 and factor

This equation is true for t=0 and for t=5.

After 5 seconds, the ball will pass the top of the building on the way down.

If the scale factor is larger then 1, the new shape is larger
if the scale factor is smaller then 1, the new shape is smaller

so if the scale factor is 3....then the length of the new rectangle is 3 times larger then the original one
