Use the properties of exponents to rewrite y=e^-0.75t in the form of a(1-r)^t

Ivahew [28]

Answer: y = (1 - 0.527)^t

Step-by-step explanation:

y=e^(-0.75t)

y=(e^-0.75)^t

y= 0.47236655^t

1 - 0.47236655 = 0.52763345

y = (1 - 0.527)^t

Line N passes through the points (–1, 4) and (–1, –4).Which is true of line N? Line N is a vertical line with an undefined slope

Marrrta [24]

Answer:

Line N is a vertical line with an undefined slope.

Step-by-step explanation:

When the points that line N passes through are graphed, they form a vertical line.

All vertical lines have an undefined slope.

We can also check if it's undefined by finding the slope.

$m=\frac{-4-4}{-1+1}=\frac{-8}{0}$

The quotient would be undefined. You cannot divide by zero.

Hope this helps.

Firdavs [7]

Answer:

y = -x -3

Step-by-step explanation:

I went to Desmos and kept guessing y intercepts until the line passed through the point (-4, 1). Sorry I can't explain the real way to figure this out.

Find the height of the triangle<br><br><br> 10 points!

Scorpion4ik [409]

By the 6 trigonometric ratios in a right triangle

(sine, cosine, tangent, cotangent, secant, cosecant)

we have the following:

$\displaystyle{ sin20^o= \frac{opposite \ side}{hypothenuse}= \frac{x}{10}$

So, $x=10\cdot sin20^o$

sin20° must be given, or can be found using a calculator:

Using the calculator of our pc: Calculator- view:Scientific- press 20 then sin button, we find : sin20°=0.342

$x=10\cdot sin20^o=10\cdot0.342=3.42$

Answer: A)3.4
