Answers
Answer:
Step-by-step explanation:
a= b^c << === >> logb(a) = c
a b c
Convert 45 = 9^√x << === >> log9 (45) = √x
1.7324867604 = √x
3.0 = x squared both sides

You have found two job offers for the beginning of the summer. Each job is only 10 days long. Job Offer #1: The offer is to receive $0.25 for accepting the job. After day one you have made a total of $1, $4 total after two days of work, $16 total after three days, etc. Job Offer #2: The offer is $16 per day with no acceptance bonus. Write an equation to represent Job Offer #1 and Write an equation to represent Job Offer #2
Answers
Answer:
[tex]f(n) = \frac{4^n-0.25}{3}[/tex] --- Job offer 1
[tex]g(n) = 16n[/tex] --- Job offer 2
[tex]1 \le n \le 10[/tex]
Step-by-step explanation:
Given
Job offer 1:
Offer = $0.25
[tex]Day 1 = \$1\ Day 2 = \$4\ Day 3 = \$16......[/tex]
Job offer 2:
Daily = $16
Required
Determine the equation for both jobs
For job offer 1:
Considering the pay for day 1, day 2,....
The sequence shows a geometry progression where the payment between subsequent days is a product of 4 by the payment of the previous day.
The sequence can be represented as:
[tex]T_1 = 1; T_2 = 4; T_3 = 16[/tex]
The common ratio (r) is:
[tex]r = \frac{T_2}{T_1} = \frac{4}{1} = 4[/tex]
The sum of n terms is the total salary received in n days.
[tex]S_n = \frac{a(r^n - 1)}{r-1}[/tex]
[tex]S_n = \frac{1 * (4^n - 1)}{4-1}[/tex]
[tex]S_n = \frac{4^n - 1}{3}[/tex]
So, the equation for job offer 1 is:
[tex]f(n) = Offer + S_n[/tex]
[tex]f(n) = 0.25+ \frac{4^n - 1}{3}[/tex]
Take LCM
[tex]f(n) = \frac{0.75 + 4^n - 1}{3}[/tex]
Collect like terms
[tex]f(n) = \frac{4^n - 1+0.75}{3}[/tex]
[tex]f(n) = \frac{4^n-0.25}{3}[/tex]
For job offer 2:
Daily payment of $16 implies that job offer 2 pays 16n for n days.
So:
[tex]g(n) = 16n[/tex]
In both cases: [tex]1 \le n \le 10[/tex]
what is the measure of the complement of a 67 degree angle?
Answers
Answer:
23°
Step-by-step explanation:
Complement angles are two angles that add up to 90°.
Since we’re given that one of them is 67°, the other one must add up to 90°
90 - 67 = 23
The other angle is 23°
Answer:
the complement of 67° is the angle that when added to 67° forms when a right angle (90°)

True or False? When you are dividing 2 numbers, you have to check to see
if there is a decimal in the divisor. If there is a decimal in the divisor, you
have to multiply that number by a power of ten to move the decimal to the
right. You have to move the decimal the same number of times to the right

Do the following setm of lengths form a right triangle 36,77, 85
Answers
Answer:
They can make a right traingle because both sides of the equation are equal these lengths do form a right triangle.
Answer:
yes
Step-by-step explanation:
Using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares of the other 2 sides then triangle is right.
longest side = 85 and 85² = 7225
36² + 77² = 1296 + 5929 = 7225
Thus the 3 sides form a right triangle

Answer: 8.6 Ft^2
Explanation:
First find the area of the WHOLE square in FEET
2.5 x 4.5 = 11.25 ft
Then we need to find the area of the circle
r = radius
The formula is A = 3.14r^2
The radius is .9166, we can tell because the total distance from top to bottom is 22in meaning 1.83333 ft, meaning the diameter is 1.8333, then to get the radius we cut that in half.
A = 3.14(.9166^2
A = 2.64 Ft
Now we need to find the new total area
11.25 - 2.64 = 8.61 in ^2
Now we need to convert it to the nearest tenth of a square foot
8.6 Ft^2

if PQ and PR are tangent to circle S,find PQ
Answers
Answer:
From one point, you can draw two tangents to a circle. These two tangents will be equal.
Step-by-step explanation:
7x - 24 = 57 - 2x.
Rearrange the numbers (by adding 2x and 24 on both sides), we get:
7x+2x = 57 + 24
9x = 81.
x = 9.
Length of PQ = 57-2x = 57 - 18 = 39
If PQ and PR are tangent to circle S, then the value of PQ is 39.
What is tangent?"A line that touches the circle at a single point is known as a tangent to a circle."
What is circle?"A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre."
P is the exterior point of a circle.
PQ and PR are the tangents to circle S.
According to theorem,
The lengths of the tangents drawn from a same external point to a circle are always equal.
7x - 24 = 57 - 2x
7x + 2x = 57 + 24
9x = 81
x = 9
PQ = 7x - 24
PQ = 7(9) - 24
PQ = 63 - 24
PQ = 39
Hence, the value of PQ is 39.

The Independent variable, also known as the predictor variable are variables used to influence and check changes in the dependent or predicted variable as subjects are exposed to the different types or levels of independent variable used in the study.
In the scenario described above, the predictor or independent variables which are used to measure the reaction times of participants to unexpected variables is the independent variable, beacuse these different variables ; nonalcoholic beer, 2 beer will probably affect the response time of the participants which is the dependent variable.
