Using the given table of an exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Type your answers in as numbers. Example: Growth Factor: 3.5, Rate of Increase: 2.5. (Do not input your rate of increase as a percent.)
f(x)=75(1-.3)^x
Answer:
0.7 is the growth factor
0.3 is the growth rate
Step-by-step explanation:
Here, we want to get the growth rate and the growth factor
Let us consider the general form of an exponential equation
That will be;
y = a(1 + r)^n
The growth rate is r
while the growth factor is the term (1 + r)
From the given exponential function;
-0.3 is the rate of increase
Growth rate is 1-0.3 = 0.7

Your savings account pays 1.75% interest per year. You make a $500 deposit. How much interest does the account earn in the first month.
The interest the account earn in the first month is = $0.73
The amount deposited( = $500
The payment rate per year = 1.75%
The payment time = per year(12 months)
Therefore simple interest in first month=
[tex] \frac{p \times t \times r}{100 \times 12} [/tex]
[tex] \frac{500 \times 1 \times 1.75}{100 \times 12} [/tex]
[tex] \frac{875}{1200} [/tex]
=$0.73
Therefore, the interest the account earn in the first month is = $0.73

which equation represents the graph?
Oliver is starting a running plan to train for a race. In the first week of his running plan, Oliver will run 14 miles. The plan calls for Oliver to increase his weekly milage by 3.5 miles every week. If Oliver sticks to the plan, how many miles would he be expected to run during his 10th week of the training plan?
Answer:
49 miles
Step-by-step explanation:
Let x be equal to the no. of weeks and y be equal to the total amount of miles ran.
Then the equation will be, y = 3.5x + 14
Now to find the amount of miles Oliver ran during the 10th week substitute 10 for x.
So, y = 3.5(10) + 14
y = 35+14
y=49

(a) Using Fermat's little theorem, show that 999 999 is divisible by 7.
(b) A number has digits that are all 9 and is divisible by 13. Show that
it is also divisible by 1001.
Part (a)
Note 999999=1000000-1. By Fermat's little theorem, since 100000=10⁶,
[tex]10^{6} \equiv 1 \pmod{7} \\ \\ \therefore 10^{6}-1 \equiv 0 \pmod{7}[/tex]
Part (b)
Note that
[tex]10^{12n}-1=(10^n)^{12}-1 \equiv 0 \pmod{13}[/tex]
Since
[tex]1 = 1001 - 1000[/tex]
and
[tex]-1 \equiv 1000 \pmod{1001}[/tex]
10³ is its own inverse modulo 1001, meaning that:
[tex]10^3 x \equiv 1 \pmod{1001} \implies x=10^3 \\ \implies 10^{12n}=(10^3 \cdot 10^3)^{2n} \equiv 1 \pmod{1001} \\ \\ \implies 10^{12n}-1 \equiv 0 \pmod{1001}[/tex]

Answer:
16. 134°
17. 20°
18. 94°
Step-by-step explanation:
An inscribed angle is half the measure of the arc it intercepts.
__
16. Arc QT is twice the measure of inscribed angle QST, given as 67°.
Arc QT = 2×67°
Arc QT = 134°
__
17. Angle STR is half the measure of arc SR, so is ...
m∠STR = (arc SR)/2 = 40°/2
m∠STR = 20°
__
18. Arc RST is a semicircle, so has a measure of 180°. Then arc ST is the difference between that and arc RS:
arc ST = 180° -40° = 140°
Angle RST subtends a semicircle, so is 180°/2 = 90°. We know angle QST is 67°, so the remaining portion, angle QSR must be the complement of that:
m∠QSR = 90° -67° = 23°
Arc RQ will be twice this measure, or 46°.
So, the desired difference is ...
mST -mRQ = 140° -46° = 94°

solve for x please i need help
Answer:
x = 4
Step-by-step explanation:
By exterior angle theorem:
(9x + 1)° + (11x - 2)° = (19x + 3)°
(9x + 1 + 11x - 2)° = (19x + 3)°
(20x - 1)° = (19x + 3)°
20x - 1 = 19x + 3
20x - 19x = 3 +1

Linda headed east at 20 miles per hour on her bicycle at 9 a.m. Three hours later Shanna headed west from the
same place, walking at 6 miles per hour. What time was it when they were 164 miles apart?
Step-by-step explanation:
Let t = time (in hrs) Linda rode her bike
Then (t-3) = Shana's time walking
:
Write a distance equation: dist = speed * time
:
Linda's dist + Shana's dist = 164
20t + 6(t-3) = 164
20t + 6t - 18 = 164
26t = 164 + 18
26t = 182
t = 182/26
t = 7 hrs, Linda is on the road
:
Time: 9 AM + 7 hrs = 4 PM, they will be 162 miles apart
:
Check using Linda's and Shana's distances:
20(7) + 6(7-3) =
140 + 24 = 164 mi

The graph represents f(x) = x +3
On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is an open circle. The right end of each segment is a closed circle. The left-most segment goes from (negative 5, negative 1) to (negative 4, negative 1). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (1, 5) to (2, 5).

edge 2020 :) have a nice day
The required value of f(-2.2) is 1 for the given function f(x)=x+3. The correct answer is an option (C).
The given function is f(x)=x+3.
To find f(-2.2) on the given graph of f(x) = x + 3, we need to locate the corresponding point on the step graph.
From the information provided, we know that the left-most segment starts at (-5, -1) and ends at (-4, -1), and each segment is 1 unit higher and 1 unit farther to the right than the previous segment.
To determine the value of f (-2.2), we need to find the segment that includes the x-coordinate of -2.2.
Since the x-coordinate -2.2 falls between -4 and -3 (1 unit to the right of the left-most segment), the corresponding y-coordinate is 2 units higher than the starting y-coordinate of -1.
So, f(-2.2) = −1 + 2
f(-2.2) = 1.
Thus, the required value of f(-2.2) is 1.
