the equation goes like this
y = ab^x
y = total cost
a = the intital amount (in your case the $1700)
b = the interest (since this is an exponetial growth it should be 1.013)
x = time
soo y = 1700(1.013)^x is the equation
Solve for u .
-3 (-6u+6) - u = 2 (u-6) - 1
Answer: U = 18
Step-by-step explanation:
U in (-oo:+oo)
U/(-6)+2 = -1 // + 1
U/(-6)+1+2 = 0
3-1/6*U = 0 // - 3
-1/6*U = -3 // : -1/6
U = -3/(-1/6)
U = 18
U = 18
Answer:
-3 (-6u+6) - u = 2 (u-6) - 1
18u -18 -u = 2u -12 -1
18u-u-2u=-12-1+18
15u= 5
u =5/15 = 1/3

Nora has nn nickels and dd dimes. She has a minimum of $2 worth of coins altogether. Write this situation as an inequality.
Answer:
0.05nn + 0.10dd ≥ 2
*make sure it is either n or nn depending whether you had a typo in problem*
Step-by-step explanation:
First each nickel is worth 0.05
each dime is 0.10
and we must have a minimum so the total value has to be at least $2
so 0.05nn + 0.10dd ≥ 2

15 m/s in km/h plz help
Answer:
54 km/h
Step-by-step explanation:
Step one:
given data
We are required to perform unit from m/s km/h
from 15m/s to km/h
Step two:
1 meter= 1/1000 km,
1 seconds= 1/3600 hour
1m/s = 1/1000/1/3600= km/h= 3600/1000= 36/10= 18/5 km/h
so of 1m/s is equivalent to 18/5 km/h
then 15m/s is equivalent to x
cross multiply
x= 15*18/5
x= 3*18
x=54 km/h

Answer: W is the correct answer just for clarification.
Step-by-step explanation:
What is the value of a if a is equal to a×a×a=a+a+a
Answer:
a = ±sqrt(3)
Step-by-step explanation:
a×a×a=a+a+a
Simplifying each side
a^3 = 3a
Divide each side by a
a^3 /a = 3a/a
a^2 = 3
Take the square root of each side
sqrt(a^2) = ±sqrt(3)
a = ±sqrt(3)
Answer:
nope its not equal
a×a×a=a³, but a+a+a=3a
so, a³≠3a

Star A is about 3.4 X 10^18 miles from Earth. Star B is 6.8 X 10^16 miles from Earth. Star A is how many times as far from Earth as Star B?
Answer:
Concept: Numerical Analysis
Star A is 3.4 ×10 ^18Star B is 6.8 × 10^16Hence we want how much farther Star A is from Star B.Hence Star A/Star B = 50 times fartherRATE BRAINLISTAnswer:
1/50 as far
Step-by-step explanation:
6.8 x 10[tex]^{16}[/tex] ÷ 3.4 x 10[tex]^{18}[/tex]
Rules state that you divide numbers and subtract exponents
6.8/3.4 = 2
10[tex]^{16}[/tex] ÷ 10[tex]^{18}[/tex] = [tex]10^{-2}[/tex]
whenever exponent is negative, it gets turned into a fraction with 1 as the numerator and the exponent will become positive when placed in the denominator
10^-2 = 1/10^2 which is the same as 1/100
2 multiplied by 1/100 = 1/50

Answer:
Terms: -8, -4c, 7, -c, -12c, -2
Variables: c
Coefficients: -4, -1, -12
Constants: -8, 7, -2
Step-by-step explanation:
Terms are anything in between a plus or minus.
Variables are anything that is not a real number, such as c.
Coefficients are the number directly before a variable, such as -4 in -4c.
Constants are any real numbers without a variable, such as -8.
Question 4 please help me
Answer:
Step-by-step explanation:
I don't know what you were supposed to do with 3 but 4 looks much easier.
It's telling you to increase the side lengths by a factor of 3y
4x(3y) + 4x(3y) = 3y * 3y
12xy + 12xy = 9y^2
Perimeter = 24xy + 9y^2
I can't see anything else to do with this question. If you think I've misread it or there is more to it, leave me a note.
Solve 2x^2+8x-1=0 can someone type this "correctly" in photo math for me please?
Answer:
Step-by-step explanation:
A statistical hypothesis testing procedure is conducted over 5000 patients about some health intervention. The p-value is 0.02. Which is true? Group of answer choices If the null hypothesis was true, the probability of observing a difference at least as large as the observed diference would be 2% the probability of observing a difference at least as large as the observed diference is 2%
Answer:
The answer is "The first choice"
Step-by-step explanation:
In the given question the first choice is correct because When the zero assumption was valid, it would have been at least as bad to also be 2% to demonstrate a discrepancy as observed difference.
Is this a square root graph?
Is this graph a reflection of its parent graph?
this graph shifted _
The equation to this graph would transform the parent function f(x) to _
Answer:
Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.
Step-by-step explanation:
Consider the function
y = f(x)
The rule of horizontal translation
y = f(x-h)
When 'h' is positive, the function is shifted to the right.
When 'h' is negative, the function is shifted to the left.
The rule of implying vertical reflection across the x-axis
y = -f(x)
Applying the rule:
We know that the square root function is
[tex]y=\sqrt{x}[/tex]
We know that if the graph would be reflected across the x-axis, then
[tex]y=-\sqrt{x}[/tex]
We know that is horizontally translated or shifted 3 units to the left, it implies +
3 inside the radical implies. Then the transformed function becomes .
Please check the attached diagram. From the diagram,
The blue graph shows the parent function [tex]y=\sqrt{x}[/tex].The red graph shows the transformed function i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.

Geometry:
What is the volume of the cone?
A. 2876.7 yd
B. 4625.36 yd
C. 4258.44 yd
D. 2787 64 yd
Answer:
D. 2787.64 yd^3
Step-by-step explanation:
This is the formula for the volume of a cone:
[tex]V=\frac{1}{3} \pi r^2h[/tex]
The height of the cone is 22 yd. The radius of the base of the cone is not given but we can use the diameter to calculate it since the radius is equal to half of the diameter.
[tex]r=\frac{1}{2}d\\r=\frac{1}{2}(22)\\r=11yd[/tex]
Therefore, the radius of the base of the cone is 11 yd.
Now, we plug our values into the formula and solve.
[tex]V=\frac{1}{3} \pi r^2h\\V=\frac{1}{3} \pi (11^2)(22)\\V=\frac{1}{3} \pi (121)(22)\\V=\frac{1}{3} \pi (2662)\\V=\frac{1}{3} \pi (2662)\\V=2787.64 yd^3[/tex]
Therefore, the volume of the cone is equal to 2787.64 yd^3.

select the correct answer for x, each answer is rounded to the nearest tenth.
Answer:
x ≈ 27.2
Step-by-step explanation:
Using the sine ratio in the right triangle
sin54° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{22}{x}[/tex] ( multiply both sides by x )
x × sin54° = 22 ( divide both sides by sin54° )
x = [tex]\frac{22}{sin54}[/tex] ≈ 27.2 ( to the nearest tenth )
