Answer:
Step-by-step explanation:
I have no idea what formula that is you're using but the one I teach in both algebra 2 and in precalculus for continuous compounding is
[tex]A(t)=Pe^{rt}[/tex]
where A(t) is the amount after the compounding, P is the initial investment, ee is Euler's number, r is the interest rate in decimal form, and t is the time in years. If our money doubles, we just have to come up with a number which will be P and then double it to get A(t). It doesn't matter what number we pick to double, the answer will come out the same regardless. I started with 2 and then doubled it to 4 and filled in the rest of the info given with time as my unknown:
[tex]4=2e^{(.062)(t)}[/tex]
Begin by dividing both sides by 2 to get
[tex]2=e^{.062t}[/tex]
The only way we can get that t out of its current position is to take the natural log of both sides. Natural logs have a base of e, so
[tex]ln_e(e)=1[/tex] This is because they are inverses of one another. Taking the natural log of both sides:
[tex]ln2=.062t[/tex] Now divide by .062 to get
t = 11.2 years
If a right triangle has an acute angle of 43 find its complement
Answer:
47°
Step-by-step explanation:
The given angle and its complement sum to 90°, thus
complement = 90° - 43° = 47°
f(x)=-(x-3)²+1 determine the vertex
Answer:
vertex = (3, 1 )
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 3)² + 1 ← is in vertex form
with vertex (h, k ) = (3, 1 )
.Solve for x.
3x = -39
Answer:
x= (-13)
Step-by-step explanation:
You need to get x alone so you have to divide by 3 and -39/3 equals -13
Answer:
x = -13
Step-by-step explanation:
Divide both numbers by 3
3÷3 cancels each other out, leaving x
-39÷3= -13

A concert is $250 per ticket and the cost of parking is free. This is expressed
as p(x) = 250x. If the profit is $6,000 how many tickets were sold?
Answer:
24
Step-by-step explanation:
p(x) = 250x
6000 = 250x
x = 24
Answer:
24 tickets
Step-by-step explanation:
p(x) = 250x
Substitute 6,000 for p(x)
6,000 = 250x
Divide each side of the equation by 250
24 = x

1. 133 1/3% of 36=?
2. 260% of 360=?
Answer:
1. 133 1/3% of 36=48
2. 260% of 360=936
Step-by-step explanation:
1. 133 1/3% of 36
=(133 1/3)% of 36
=(133/1+1/3)% of 36
=(399+1/3)% of 36
=(400/3)% of 36
=(400/3 *100) *36
=(400/300*36)
=4/3*36
=4*12
=48 Ans
---------------------------------------------------------------------------------------
2. 260% of 360
=260% of 360
=260/100*360
=26/10*360
=26/1*36
=936 Ans

A rectangular prism has the following dimensions. The base has sides that are 3 cm. and 5 cm. and the height is 9 cm. How many squares with 1 cm edges can cover the entire surface area of the prism completely with no overlaps?
Answer:
174 squares
Step-by-step explanation:
I would start by finding the surface area of the rectangular prism. You can use 2(wl+hl+hw).
2(wl+hl+hw)
2(3*5+9*5+9*3)
2(15+45+27)
2(87)
174 cm^2
The area of squares 1 cm edges would be 1 because 1*1=1, so you could find how many of them would fit on the surface area by dividing 174 by 1, which equals 174.
2(h - 8) - h = h - 16
[tex]2(h-8)-h=h-16[/tex]
[tex]2h-16-h=h-16[/tex]
[tex]h=h[/tex]
h has infinitely many solutions.

What is the equation of a line perpendicular to y=-2/5X-1 that passes through (2,-8)
Answer:
[tex]y=\frac{5}{2}x-13[/tex]
Step-by-step explanation:
Given the equation
[tex]y=-\frac{2}{5}x-1[/tex]
comparing the equation with the slope-intercept form[tex]y=mx+b[/tex]
Here,
m is the slope b is the interceptso the slope of the line is m = -2/5
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line,
so the slope of the perpendicular line will be: 5/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (2,-8) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-8\right)=\frac{5}{2}\left(x-2\right)[/tex]
[tex]y+8=\frac{5}{2}\left(x-2\right)[/tex]
subtract 8 from both sides
[tex]y+8-8=\frac{5}{2}\left(x-2\right)-8[/tex]
[tex]y=\frac{5}{2}x-13[/tex]

EASY!!!! Answer this question correctly
Answer:
1st answer choice- You do not have enough jars because 20 jars will only hold 35 cups of applesauce.
Step-by-step explanation:
So 1.75 cups of applesauce fits in a jar. You have 20 jars so you multiply the cups of applesauce that can fit in the jar by how many jars you have. It will look like this: 1.75x20=? Now you multiply them and you get 35 which is how many cups of applesauce 20 jars will hold. You will have 5 cups of applesauce left over that cannot be transformed into a jar.
If you can please make my answer the brainliest that would be much appreciated. Thanks!

solve:3x=40+x
pls solve this fast
Answer:
x = 20
Step-by-step explanation:
3x = 40 + x

2x = 40
Divide both sides by 2
x = 40/2
x = 20
