Answer:

A. 98

Step-by-step explanation:

This is the exterior angle theorem I'm pretty sure.

This means that 24 + x, would equal 122.

So, 24 + x = 122.

Do the algebra. Subtract on both sides, so 122 - 24 would be 98.

So x = 98

Angle BAD and angle BAC are supplementary angles, which means they add up to 180 degrees.

180 = 122 + ?

Subtract 122 from both sides.

BAC = 58 degrees.

We know that the sum of all the interior angles of a triangle is 180 degrees.

180 = 24 + 58 + x

Combine like terms.

180 = 82 + x

Subtract 82 from both sides.

98 degrees = x

Answer choice A is correct

In the parallelogram shown, find x.

Olin [163]

The side with all the 9s and x is 12 just like its opposite side because this is a parallelogram. We can write the equation to add up the three segments; the ones on the left and right are 9-x:

9-x + x + 9-x = 12

18 - x = 12

x = 6

The number y of hits a new website receives each month can be modeled by y = 4070ekt, where t represents the number of months th

makvit [3.9K]

Answer:

k = 0.2645

Step-by-step explanation:

Given model:

y = 4070 $e^{kt}$

y = no. of hits website received = 9000 (in 3rd month)

t= no. of months website has been operational = 3

put in the above equation:

9000 = 4070 $e^{3k}$

$\frac{9000}{4070}$ = $e^{3k}$

$\frac{900}{407}$ = $e^{3k}$

Taking natural logarithm on both sides, we get:

$ln\frac{900}{407}$ = $ln(e^{3k})$

$ln\frac{900}{407}$ = 3k lne

lne=1

$ln \frac{900}{407}$ = 3k

or k = $\frac{1}{3}$ $ln\frac{900}{(407)}$

k = $\frac{1}{3}$ (0.7936)

k = 0.2645
