In normal line integration, from what I understand, you are measuring the area underneath (,)
f
(
x
,
y
)
along a curve in the -
x
-
y
plane from point
a
to point
b
.

Find y. Please help!

Anit [1.1K]

Answer:

$y\approx 11.9$

Step-by-step explanation:

Here, we have the known angle sandwiched between two known sides.

So, we have SAS.

And we want to find the side opposite to the angle.

Therefore, we can use the Law of Cosines:

$c^2=a^2+b^2-2ab\cos(C)\\$

Again, it is important what we substitute.

a and b are the two side lengths. So, we will substitute 8 for a and 13 for b.

C is our angle. So, substitute 64 for C.

And c is what we’re trying to solve.

Therefore:

$c^2=(8)^2+(13)^2-2(8)(13)\cos(64)$

Simplify:

$c^2=64+169-208\cos(64)$

Add:

$c^2=233-208\cos(64)$

Take the square root of both sides:

$c=\sqrt{233-\cos(64})$

Use a calculator. So, c is approximately:

$c\approx11.9$

The c is our y. So, y is approximately 11.9 units.

Estimate 58% of 121 by using 10%. show work please

Setler [38]

Answer:

58% of 121 by using 10% is 70.18.

Step-by-step explanation:

58% is about equal to 60%, or 6 times 10%. 10% of 121 is 12.1.

12.1 * 6 = 72.6

To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.

72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18

If a child is randomly selected from Columbus elementary school, what is the probability that the child will be a boy?

lora16 [44]

Answer:

$G+35 -3G=25$

$2G = 10, G =5$

$B = G+35 = 40$

So then the correct option would be:

C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.

Step-by-step explanation:

Assuming the following options:

A. Statement 1 ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient.

B. Statement 2 ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient.

C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.

D. Each statement ALONE is sufficient to answer the question.

E. Statement 1 and 2 TOGETHER are NOT sufficient to answer the question.

Notation

Let B the event that we select a boy and G the event that we select a girl.

We are interested in find the probability of being boy, on math would be:

$P(B) = \frac{B}{B+G}$

From condition (1) we can do this:

$\frac{B-25}{(B-25)+G} = 0.75 =\frac{3}{4}$

$4B - 100 = 3B -75 +3G$

$B -3G = 25$ (1)

As we can see we have two unknown and we can't solve the system.

Now from condition (2) we can do this:

$B= G+35$ (2)

We see that condition (2) alone is not enouch to solve the problem.

And we need both conditions in order to solve the problem. If we replace equation (2) into equation (1) we got this:

$G+35 -3G=25$

$2G = 10, G =5$

$B = G+35 = 40$

So then the correct option would be:

C. BOTH statements 1 and 2 TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.
