The value of [tex]7^x = 77[/tex] is C. x = 0.45 obtained by taking log of vase 7 on both sides.
What is a logarithm?The logarithm is exponentiation's opposite function in mathematics.
This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.
Given, an expression [tex]7^x = 77[/tex].
Now, [tex]log_77^x = log_7(77)[/tex].
We have taken log of base 7 on both sides to cancel out log base 7 of 7 to get x explicitly.
[tex]x = log_777[/tex].
x = 0.4479 Or x = 0.45.

Write a function called Radians_To_Degrees which will convert an angle from Radians to Degrees. In your Lesson 06 script: a. convert 1.62 radians to degrees b. Convert pi/9 radians to degrees
Answer:
a) 92.9 degrees
b) 20 degrees
Step-by-step explanation:
Using the conversion factor;
180 degrees = pi radians
For 1.62 radians;
1.62 radians = x
pi radians = 180 degrees
Divide both expressions;
1.62/pi = x/180
pi * x = 1.62 * 180
pi * x = 291.6
x = 291.6/pi
x = 291.6/3.14
x = 92.9 degrees
Hence 1.62 radians is equivalent to 92.9 degrees
b) Recall that
pi radians = 180 degrees
pi/9 rad = y
Cross multiply
y * pi = 180pi/9
y = 180/9
y = 20 degrees
Hence pi/9 radians is equivalent to 20 degrees

Answer:
x = 8.2
Step-by-step explanation:
As indicated on the supplied diagram, the measure of arc GH is ...
GH = 360° -83° -115° = 162°
The inscribed angle at F is half this measure, so we have ...
(10x -1)° = 162°/2
10x = 82 . . . . . . . . add 1 and simplify

6. Missing data, nonrandom samples, and outlying observations True or False: If the data for an observation on either the dependent variable or one of the independent variables are missing at random, then the size of the random sample available from the population must be reduced, which reduces the estimator's precision and introduces a bias.
Answer:
False
Step-by-step explanation:
The answer to this question is false because the missing observation does not introduce bias to the estimator. But missing observations reduces the size of the sample that is available from the given population. Therefore reducing the precision of the estimators.
In conclusion, no bias is introduced because of missing observations so the answer is false.

Calculate the area of the figure in square centimeters.
Answer:
20.283
Step-by-step explanation:
1) the formula of the required Area is:
A=A₁+A₂, where A₁ - area of semicircle, A₂ - area of rectangular;
2) the radius of the semicircle is: r=(7-2-1)/2=2 cm, then the area A₁:
A₁=0.5*π*r²=2π≈6.283 (cm²);
3) A₂=7*2=14 (cm²);
4) finally, A=A₁+A₂=6.283+14=20.283 (cm²)

A local hamburger shop sold a combined total of 390 hamburgers and cheeseburgers on Wednesday. There were 60 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Wednesday?
Answer:
225 hamburgers
Step-by-step explanation:
system of equations:
h + c = 390
c = h-60
use Substitution:
h + h - 60 = 390
2h - 60 = 390
2h = 450
h = 225
Bailey wanted a new pair of shoes. She put the $142 cost on her
credit card. Because Bailey has been irresponsible with her credit,
the credit card company charges her 22% annual interest. Figure
Bailey's balance after 180 days, assuming she made no payments.
Answer:
Bailey's balance after 180 days is $ 157.39.
Step-by-step explanation:
Since Bailey wanted a new pair of shoes, and she put the $ 142 cost on her credit card, but because Bailey has been irresponsible with her credit, the credit card company charges her 22% annual interest, for figure Bailey's balance after 180 days, assuming she made no payments, the following calculation must be made:
365 = 100
180 = X
180 x 100/365 = X
18,000 / 365 = X
49.31 = X
22 x 0.4931 = 10.84
142 x 1.1084 = X
157.39 = X
Thus, Bailey's balance after 180 days is $ 157.39.

The difference between twice a number and 16 is 30. Which math statement is an equation that represents this relationship?
A) 30 – 16 = x
B) x – 16 = 30
C) 2x + 16 = 30
D) 2x – 16 = 30
E) 2x + 30 = 16
Answer:
D
Step-by-step explanation:
Answer:
D is the correct answer :)
Step-by-step explanation:
Hi,
Twice a number is 2x (x because we don't know what that number is) The word "difference" suggests we're subtracting. So, 2x - 16 = 30 is correct.

Consider functions f and g.
f(x) = log(x - 1)
g(x) = 1/3x^2 - 4
Which statement is true about the solutions of the equation f(x) = g(x)?
Answer:[tex]g (f (x)) = 3^{2} + 24[/tex]
Step-by-step explanation:
The true about the solutions of the equation f(x) = g(x) is
The solution of the graph where the graph of function intersect at
x = 1 and x = 3.642.
What is Function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).
We have function,
f(x) = log(x - 1)
g(x) = 1/3x² - 4
As, f(x) = g(x)
log (x-1) = 1/3 x² - 4
Now, putting x= 1, x= 3.642, x= 4.464, x= 4 , x= 0.422 into the formula for the observation.
So, the solution of the graph where the graph of function intersect at
x = 1 and x = 3.642

Last 3 questions thank you so much
Answer:
Step-by-step explanation:
1)
we are given ∠17 and the Adj = 200 meters they want to know the Opp
so use TOA
Tan(17) = Opp / 200
200*Tan(17) = Opp
61.146 = Opp
the mast stands 61.1 meters tall ( rounded to nearest 10th )
2)
now we know the opp = 40 meters and the angle is 35° and Adj = x
Use TOA again, but w/ the different knowns
Tan(35) = 40 / Adj
Adj = 40 / Tan(35)
57.1259 = Adj
so the boat is 57.1 meters from the cliff ( rounded to nearest 10th)
3)
we are given two triangles now and are told to find the difference between them to find the distance between the buoys
Opp = 70
∠A = 60
∠B = 40
we want to find the Adj for each so use TOA
for A , then
Tan(60)= 70/a
a = 70 / Tan(60)
a = 40.4145
for B, then
Tan(40) = 70 /b
b = 70 / Tan(40)
b = 83.4227
so subtract a from b
83.4227 - 40.4145 = 43.008
so from buoy A to buoy B is 43.0 meters ( rounded to nearest 10th )
:)
