The price of a computer fell 20% this year. If the computer now costs $750, how much did it cost last year?
(step-by-step if possible)
Answer:
$937
Step-by-step explanation:
P(1-20/100)=750- 1 is the object the you take away the percentage that is in
fraction form
P(1-.2)=75-take it from fraction form to decimal form
P(.8)=750-this is the final product of the equation above
750/.8-Take the current price and the decimal and divide
75000/80- take the .8 and add two 0's to get the whole accurate amount
937.5-Price before the price fell

A car's rear windshield wiper rotates 140°. The total length of the wiper mechanism is 24 inches and the length of the wiper blade is 16 inches. Find the area wiped by the wiper blade. (Round your answer to one decimal place.)
Answer:
312.7 in^2Step-by-step explanation:
This problem is on the mensuration of flat shapes, sectors and arc.
we know that the area of a sector is given as
A=(∅/360)*πr^2
Given that the length of the wiper R=24 in
and the length of the blade r= 16in
To find the area of the wiped surface we only require the length of the blade as the radius
The area of the wiped surface is given as= (140/360)*3.142*16^2
A= 0.3888*3.142*256
A=312.7 in^2

You can let me know, but i dont think -3x² is supposed to be squared in this question because then it would make it unsolvable.
5x-15
can be simplified to 5(x-3)
x²-3x
can be simplified to x(x-3)
Then u rewrite it (5 + x)(x - 3)
How would you do this question?
Answer:
1) ∫ x² e^(x) dx
4) ∫ x cos(x) dx
Step-by-step explanation:
To solve this problem, eliminate the choices that can be solved by substitution.
In the second problem, we can say u = x², and du = 2x dx.
∫ x cos(x²) dx = ∫ ½ cos(u) du
In the third problem, we can say u = x², and du = 2x dx.
∫ x e^(x²) dx = ∫ ½ e^(u) du

You intend to estimate a population mean μ with the following sample. 78.4, 85.3, 50, 68.4, 59.4, 73.7, 73.2, 47.4, 40.5
You believe the population is normally distributed.
Find the 99.5% confidence interval.
The answer must be done as an open-interval accurate to 2 decimal places.
Answer:
(17.75, 110.32)
Step-by-step explanation:
The sample mean is 64.03, and the standard deviation is 15.43.
The population is normally distributed, so 99.5% confidence is ±3 standard deviations.
The confidence interval is therefore:
(64.03 − 3 × 15.43, 64.03 + 3 × 15.43)
(17.75, 110.32)
The 99.5% confidence interval will be equal to (17.75, 110.32).
What is Probability?Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.
As per the given data provided by the question,
With a standard deviation of 15.43 and a sample mean of 64.03, respectively.
Since the population has normally distributed, 99.5% probability lies within a range of three standard deviations.
Consequently, the confidence interval is:
= (64.03 − 3 × 15.43, 64.03 + 3 × 15.43)
= (17.75, 110.32), this is up to 2 decimal places.

Find the equation of the line that has the given properties. Express the equation in slope-intercept form.
Slope = -9; y-intercept = 5
What is the equation of the line?
Answer:
y = -9x +5Step-by-step explanation:
Slope = -9
y-intercept = 5
In [tex]y = mx +b[/tex] ;
m = slope
b = y-intercept
So just replace -9 for m and 5 for b in slope intercept form;
[tex]y = -9x +5[/tex]

Answer:
x=3
Step-by-step explanation:
15 – 2x=3x
Add 2x to each side
15 – 2x+2x=3x+2x
15 = 5x
Divide each side by 5
15/5 = 5x/5
3 =x
Answer:

15 - 2x = 3x
Add 2x to both sides
15 = 5x
Divide 5 to both sides

May you please answer question #9
Answer: Approximately 0.78388 seconds
==========================================
Explanation:
Plug in t = 0 to find that
h = -16t^2 - 64t + 60
h = -16(0)^2 - 64(0) + 60
h = 60
The starting height is 60 feet.
-----
Now plug in h = 0 and solve for t.
h = -16t^2 - 64t + 60
0 = -16t^2 - 64t + 60
-16t^2 - 64t + 60 = 0
From here use the quadratic formula
[tex]t = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t = \frac{-(-64)\pm\sqrt{(-64)^2-4(-16)(60)}}{2(-16)}\\\\t = \frac{64\pm\sqrt{7936}}{-32}\\\\t = \frac{64+\sqrt{7936}}{-32} \ \text{ or } \ t = \frac{64-\sqrt{7936}}{-32}\\\\t \approx -4.78388 \ \text{ or } \ t \approx 0.78388 \\\\[/tex]
We ignore the negative t value as a negative time doesn't make sense.
The only practical answer is roughly t = 0.78388 seconds.
In Exercises 37– 40, BD ⃗ bisects ∠ABC. Find m∠ABD,
m∠CBD, and m∠ABC.
Answer:
37, ABD = CBD = 44 degrees, and ABC = 88 degrees
38. ABD = CBD = 24 degrees, and ABC = 48 degrees
39. ABD = CBD = 65 degrees, and ABC = 130 degrees
40. ABD = CBD =67 degrees, and ABC = 134 degrees
Step-by-step explanation:
Recall that when a segment bisects an angle, the angle is divided in equal parts then we have:
37.
6 x + 14 = 3 x + 29
3 x = 19 - 14 = 15
x = 15/3
x = 5
then ABD = 6 (5) + 14 = 30 + 14 = 44 degrees
CBD must equal ABD , so CBD = 44 degrees
And the total angle ABC = 88 degrees
38.
3 x + 6 = 7 x - 18
24 = 4 x
x = 24/4 = 6
Then ABD = 3 (6) + 6 = 24 degrees. Also CBD = 24 degrees and ABC = 48 degrees
39.
- 4 x + 33 = 2 x + 81
- 6 x = 81 - 33
-6 x = 48
x = - 48/6
x = -8
Then ABD = -4 (-8) + 33 = 32 + 33 = 65 degrees
The also CBD = 65 degrees, and ABC = 130 degrees
40.
8 x + 35 = 11 x + 23
35 - 23 = 11 x - 8 x
12 = 3 x
x = 12/3
x = 4 degrees
Therefore:
ABD = 8 (4) + 35 = 32 + 35 = 67 degrees.
Then also CBD = 67 degrees, and ABC = 134 degrees

A steel woodworking blade is created from a rectangular mold with vertices at (0, 0), (0, 1), (4, 0), and (4, 1). (All coordinates are in centimeters). At each point of the blade, the thickness, in milimeters, is equal to twice the y-coordinate. Find the height of the balance point of the blade.
Answer:
5.6 cm
Step-by-step explanation:
Given that a steel woodworking blade is created from a rectangular mold with vertices at (0, 0), (0, 1), (4, 0), and (4, 1). (All coordinates are in centimeters). At each point of the blade, the thickness, in milimeters, is equal to twice the y-coordinate.
The x axis or the horizontal length will be L = (1 - 0)^2 + ( 0 - 0 )^2
L = 1 cm
The y axis or the vertical length will be
L = sqrt ( [ 4-0]^2 + [0-0]^2)
L = Sqrt(16)
L = 4 cm
Given that at each point of the blade, the thickness, in milimeters, is equal to twice the y-coordinate.
That is,
Thickness = 2 × 4 = 8 mm
The height of the balance point of the blade will be;
Height = 8 mm + 4 cm + 8 mm
Height = 0.8 + 4 + 0.8
Height = 5.6 cm
Note that the thickness will be added to both the top and the bottom of the blade.
