Two sides of a parallelogram are 500 feet and 790 feet. The measure of the angle

Nat2105 [25]

Answer:

215117 ft²

Step-by-step explanation:

Assumed the base is the longer side.

The height of the parallelogram is:

h/500 = sin 33°
h = 500 sin 33°
h = 272.3 ft

The area is:

A = bh
A = 790*272.3 = 215117 ft²

What is the value of –4.00 –0.25 1.51 2.41

soldier1979 [14.2K]

For this case we must resolve the following expression: $log_ {0.5} (16)$

We have to:

$log_ {a} (x) = \frac {log_ {b} (x)} {log_ {b} (a)}$

The base change rule can be used if a and b are greater than 1 and are not equal to x.

We substitute the values in the base change formula, using $b = 10$

$\frac {log (16)} {log (0.5)} = - 4$

Answer:

-4

Option A

At 82°F, a certain insect chirps at a rate of 61 times per minute, and at 91°F, they chirp 124 times per minute. Write an equati

Ganezh [65]

Answer:

$y=7x-513$

Step-by-step explanation:

Let

x----> the temperature in degrees Fahrenheit

y ---->insect chirping rate in times per minute

we have the ordered pairs

(82,61) and (91,124)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{124-61}{91-82}$

$m=\frac{63}{9}=7$

step 2

Find the equation of the line

we know that

The equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=7$ ---> the units are chirps per minute/degree F

take the point (82,61)

substitute and solve for b

$61=7(82)+b$

$61=574+b$

$b=-513$

substitute

$y=7x-513$
