Answer:
333cm^2
Step-by-step explanation:
Divide the compound shape into the two separate parts, the rectangle and the triangle.
The rectangle measuring 18cm by 14cm, getting the area, use the formula length*width. This is 18*14= 252cm^2.
Then the triangle has the height, 9cm and base 18cm, finding the area use the formula, 1/2*base*height.
1/2*9*18= 81cm^2.
Add the two, 252+81= 333cm^2.

Answer:
(a) y = ¼ sin(x² + C)
(b) y = ¼ sin(x²)
Step-by-step explanation:
(a) dy/dx = ½ x √(1 − 16y²)
dy / √(1 − 16y²) = ½ x dx
4 dy / √(1 − 16y²) = 2x dx
sin⁻¹(4y) = x² + C
4y = sin(x² + C)
y = ¼ sin(x² + C)
(b) When x=0, y=0.
0 = ¼ sin(C)
C = 0
y = ¼ sin(x²)

A sample of 68 electric motors had a mean efficiency of 0.595 (assume that the standard deviation is known to be 0.05). Let μ represent the mean efficiency of electric motors of this type.
Find the P-value for testing H0 : μ ≥ 0.6 versus H1 : μ < 0.6.
P-value =
The p-value for the test hypothesis is of 0.4681.
How to find the p-value of the test?We are working with proportions in this problem, hence the z-distribution is used, first we find the test statistic, and then with the test statistic, we find the p-value.
The test statistic is given according to the following rule:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which the parameters of the formula are described as follows:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.In the context of this problem, the values of these parameters are given by:
[tex]p = 0.6, \overline{p} = 0.595, n = 68[/tex]
Hence the test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.595 - 0.6}{\sqrt{\frac{0.6(0.4)}{68}}}[/tex]
z = -0.08
Using a z-distribution calculator, with a left-tailed test, as we are testing if the proportion is less than a value, the p-value is of 0.4681.

What this is saying is it is taking the cubed root (which is like a square root, except it is using a 3 instead of 2) of x to the power of 10 divided by 64.
The equation is also saying:
[tex]\frac{\sqrt[3]{x^{10} }}{\sqrt[3]{64} }[/tex]
We can simplify the bottom half of the fraction to be 4. The cube root of something is essentially saying its the number times itself 3 times (in this case, divided by that original number). The number to get to 64 was 4 and it was done like this: 4 times 4 times 4 (which equals 64).
As for the top equation, it will simplify down to [tex]x^{3} \sqrt[3]{x}[/tex].
Since [tex]x^{10}[/tex] can be broken up to be x and [tex]x^{9}[/tex], we cube root the [tex]x^{9}[/tex] to become [tex]x^{3}[/tex], while the x remains the same.
We come to result of [tex]\frac{x^{3}\sqrt[3]{x} }{4}[/tex], which is the answer.

The equation is y =
(please help me)
Answer:
y = 2x - 26
Step-by-step explanation:
y = [tex]-\frac{1}{2}[/tex] x - 9 ⇒ slope m = [tex]-\frac{1}{2}[/tex] ⇒ slope of ⊥ line m = 2
(13, 0)
y - 0 = 2(x - 13)
y = 2x - 26
What slope would make the lines
perpendicular?
y = -x + 2
y = [?]x – 1
Answer:
The inverse reciprocal.
The slope of a perpendicular line is always the inverse reciprocal.
Answer:
3Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
The slope m of a perpendicular line is always the inverse reciprocal.
Therefore, our mperpendicular is 3.

The function C gives the cost, in dollars, to shred w pounds of confidential documents of a company.
Interpret the meaning of the following math sentence in the context of the problem. C'(500) = 80.
The model shows cost is increasing at a rate of $80 dollars/pound.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
We given C gives the cost, in dollars, to shred w pounds of confidential documents of a company.
Also, the modeled equation :C’(500)=80
which shows that for 500 pounds of documents, the cost is increasing at a rate of $80 dollars/pound.
Hence, one pound costs $80.

A container holds 80,000 ounces of water. There is a small leak in the container. Every 96 minutes, 0.3 ounces of water leak out. Represent the total change in the amount of water in the container after 8 hours.
Answer:
Step-by-step explanation:
8hours=60×8= 480 minute
96minutes=0.3 ounces
480minutes =x ounces (use crisscross)
96x =144minutes
X= 144/96=1.5 ounces
Total change in the amount of water is
80,000-1.5=79998.5 ounces
