Answer:

speed = distance/time

distance = 60 miles

time = 1.5 h

speed = 60/1.5

= 40 miles per hour

so the answer in the pic is the correct answer

First write both vectors in terms of their horizontal and vertical components.

G = (40.3 m)(cos(-35.0º) x + sin(-35.0º) y)

G = (33.0 x - 23.1 y) m

(where x and y are the unit vectors that point in the positive horizontal and vertical directions, respectively)

H = (63.3 m)(cos 270º x + sin 270º y)

H = (-63.3 y) m

Then the vector sum is

G + H = (33.0 x - 86.4 y) m

which has a magnitude of

|| G + H || = √[33.0^2 + (-86.4)^2] = 92.5 m

The function LaTeX: f\left(x\right)=2\cdot5^xf ( x ) = 2 ⋅ 5 x can be used to represent an exponential growth curve. Which of th
masha68 [24]

Answer:

(2,20)

Step-by-step explanation:

The given function is

f(x) = 2 \cdot \:  {5}^{x}

To see which point is not on this curve, we must substitute the points to see which does not satisfy the equation;

For the first point we substitute x=3 and f(x)=250

250= 2 \cdot \:  {5}^{3}  \:  \\ 250 = 2 \times 125 \\ 250 = 250

This is true.

For the second point (2,20), we put x=2 and y=20 to get:

20= 2 \cdot \:  {5}^{2}  \\ 20 = 2 \times 25 \\ 20 = 50

This is false, hence (2,20) does not lie on this curve.

For (1,10), we have:

10= 2 \cdot \:  {5}^{1}  \\ 10 = 10

This is also true

Finally for (2,50), we have;

50= 2 \cdot \:  {5}^{2}  \\ 50 = 2 \times 25 \\ 50 = 50

This is also true.

I can’t really understand this can someone help<br> Me?

The answer is 4/5 because there are 20 in total squared and circles but the total shapes is 25 so simplify the fraction 20/25=4/5
