Find The Value For The Side Marked Below.Round Your Answer To The Nearest Tenth.50122yy = [?Enter

Answers

Answer 1

Answer:

y = 189.8

Step-by-step explanation:

Apply trigonometric function to find y.

Reference angle (θ) = 50°

Adjacent side = 122

Hypotenuse = y

Apply CAH, since the Hypotenuse and the Adjacent are involved.

Thus:

Cos θ = Adj/Hypo

Plug in the values

Cos 50° = 122/y

y*Cos 50° = 122

y = 122/cos 50°

y = 189.8 (beater tenth)

Choose the fraction that is greater than 5/9

Answers

Answer:  Choice D)   14/23 > 5/9

===========================================

Convert each fraction shown to decimal form

5/9 = 0.555557/16 = 0.43750  8/15 = 0.53333 6/11 = 0.54545 14/23 = 0.60870

With the exception of 7/16 = 0.43750, the other decimal values are approximate.

From that list, we can see the decimal representations of 7/16, 8/15, and 6/11 are all smaller than the decimal version of 5/9. So we rule out choices A, B, and C. The answer must be choice D.

Sure enough, 14/23 = 0.60870 is indeed larger than 5/9 = 0.55555

---------------------

We can show this another way:

First off, assume that 14/23 and 5/9 are equal. We'll cross multiply and show a contradiction happens

14/23 = 5/9

14*9 = 23*5

126 = 115

The contradiction happens since we should get the same value on both sides if the two sides were equal, but they're not equal.

If we replace each equal sign with a greater than sign, then we get,

14/23 > 5/9

14*9 > 23*5

126 > 115

You can think of it like working backwards up the chain.

~ Hope this helped u Kaitilyn :)))))

Answer:

11/26 is red, 10/26 is yellow, and 5/26 is blue

Step-by-step explanation:

So, to find the probabilities, we must figure out the total amount of frequency found. To do this lets add up the frequencies of red blue and yellow:

11+10+5 = 26

So our total is 26.

This will be the denominator of our fractions. The numerator will be the amount of the specific freuqency we are looking at.

So reds would be:

11/26 - Frequency of red over Total frequency = Ratio

10/26 - Frequency of red over Total frequency = Ratio

5/26 - Frequency of red over Total frequency = Ratio

So these are your 3 answers!

Find the solution of the differential equation that satisfies the given initial condition.
dy/dx = x/y, y(0) = −3

Answers

Answer:

y=-sqrt(x^2+9)

Step-by-step explanation:

This problem can be solved with the help of separating the variables.

dy/dx=x/y

Multiply both sides by y

y dy/dx=x

Multiply both sides by dx

y dy=x dx

Integrate

y^2/2=x^2/2+c

Let's find c using the condition y(0)=-3.

(-3)^2/2=(0)^2/2+c

9/2=0+c

9/2=c.

The equation is y^2/2=x^2/2+9/2.

Let's make this a bit prettier multiplying both sides by 2:

y^2=x^2+9

Taking square root of both sides gives:

y=+/- sqrt(x^2+9)

Since we want y(0)=-3, then we will choose

y=-sqrt(x^2+9).

A communications company has developed three new designs for a cell phone. To evaluate consumer response, a sample of n = 120 college students is selected and each student is given all three phones to use for one week. At the end of the week, the students must identify which of the three designs they prefer. The distribution of preference is as follows:

Design 1 Design 2 Design 3
54 38 28

Required:
Do the results indicate any significant preferences among the three designs?

Answers

Answer:

There is significant preference among the 3 designs

Step-by-step explanation:

Given :

Design 1 Design 2 Design 3

54 38 28

H0 : no significant preference among the 3 designs

H1 : The preference among the designs are different

To test, we use the Chisquare test for independence ;

χ² = (observed - Expected)² / Expected

The sample size, n = 120

Expected = 120 / number of designs = 120 / 3 = 40

(54-40)^2/ 40 + (38 - 40)² / 40 + (28 - 40)² / 40

= 4.9 + 0.1 + 3.6

= 8.6

The Chisquare critical value at 95% = 5.99

Since ;

|χ² critical| < χ² statistic ; we reject the null and conclude that there is significant preference among the 3 designs

Assume that x and y are both differentiable functions of t and find the required values of dy/dt and dx/dt.

xy = 2

a. Find dy/dt, when x = 4, given that dx/dt = 13.
b. Find dx/dt, when x = 1, given that dy/dt = -9.

Answers

Answer:

a. [tex]\frac{dy}{dt} = -\frac{13}{8}[/tex]

b. [tex]\frac{dx}{dt} = \frac{9}{2}[/tex]

Step-by-step explanation:

To solve this question, we apply implicit differentiation.

xy = 2

Applying the implicit differentiation:

[tex]y\frac{dx}{dt} + x\frac{dy}{dt} = \frac{d}{dt}(2)[/tex]

[tex]y\frac{dx}{dt} + x\frac{dy}{dt} = 0[/tex]

a. Find dy/dt, when x = 4, given that dx/dt = 13.

x = 4

So

[tex]xy = 2[/tex]

[tex]4y = 2[/tex]

[tex]y = \frac{2}{4} = \frac{1}{2}[/tex]

Then

[tex]y\frac{dx}{dt} + x\frac{dy}{dt} = 0[/tex]

[tex]\frac{1}{2}(13) + 4\frac{dy}{dt} = 0[/tex]

[tex]4\frac{dy}{dt} = -\frac{13}{2}[/tex]

[tex]\frac{dy}{dt} = -\frac{13}{8}[/tex]

b. Find dx/dt, when x = 1, given that dy/dt = -9.

x = 1

So

[tex]xy = 2[/tex]

[tex]y = 2[/tex]

Then

[tex]y\frac{dx}{dt} + x\frac{dy}{dt} = 0[/tex]

[tex]2\frac{dx}{dt} - 9 = 0[/tex]

[tex]2\frac{dx}{dt} = 9[/tex]

[tex]\frac{dx}{dt} = \frac{9}{2}[/tex]

(a) For maximum height, put dh/dt = 0

So,

Answer:

You are right, it's B

Step-by-step explanation:

Complementary angles are angles that add up to 90 degrees.

Answer:

The answer is B. the measure of angle GPF and the measure of angle GPH.

Step-by-step explanation:

Two angles are called complementary when their measures add to 90 degrees.

Since the measure of angle FPD has a known angle measure of 90 degrees, the measure of angle FPH is also 90 degrees.

Thus, causing the measure of angle GPF and the measure of angle GPH to add up to 90 degrees, which makes the two angles complementary.
