Can someone pls help. Been on this question for almost an hour

Answer:

A = 23°

b = 9.5

c = 14.7

Step-by-step explanation:

B = 32°

C = 125°

a = 7

✔️Find A:

A = 180° - (B + C) (sum of triangle)

A = 180° - (32° + 125°)

A = 23°

✔️Find b using Law of Sines:

[tex] \frac{sin(A)}{a} = \frac{sin(B)}{b} [/tex]

Plug in the values

[tex] \frac{sin(23)}{7} = \frac{sin(32)}{b} [/tex]

Cross multiply

[tex] sin(23)*b = sin(32)*7 [/tex]

Divide both sides by sin(23)

[tex] b = \frac{sin(32)*7}{sin(23)} [/tex]

b = 9.5 (nearest tenth)

✔️Find c using Law of Sines:

[tex] \frac{sin(A)}{a} = \frac{sin(C)}{c} [/tex]

Plug in the values

[tex] \frac{sin(23)}{7} = \frac{sin(125)}{c} [/tex]

Cross multiply

[tex] sin(23)*c = sin(125)*7 [/tex]

Divide both sides by sin(23)

[tex] c = \frac{sin(125)*7}{sin(23)} [/tex]

c = 14.7 (nearest tenth)

Answer:

  (x, y) = (-1 2/9, 11 1/9)

Step-by-step explanation:

My favorite solution method is a graphing calculator. It shows the solution to this system of equations is ...

  (x, y) = (-1 2/9, 11 1/9)

__

When the solutions are not integers, sometimes solutions involving elimination or substitution get into arithmetic with fractions. Using matrix methods, such as Cramer's Rule can avoid that until the last step. Here, we'll use a "cross multiplication" method.

First we put both equations into general form.

  5x +y -5 = 0

  x +2y -21 = 0

Now, we consider the array of coefficients, with the first repeated as the last:

  5, 1, -5, 5

  1, 2, -21, 1

The differences of cross products of adjacent columns are ...

  d1 = (5)(2) -(1)(1) = 10 -1 = 9

  d2 = (1)(-21) -(2)(-5) = -21 +10 = -11

  d3 = (-5)(1) -(-21)(5) = -5 +105 = 100

The relation ...

  1/d1 = x/d2 = y/d3

specifies how these differences are used to find the solutions.

  x = d2/d1 = -11/9 = -1 2/9

  y = d3/d1 = 100/9 = 11 1/9

The solution is (x, y) = (-1 2/9, 11 1/9).

Answer is 11

-(-7+4)

Firstly, negative times negative equals to positive so It becomes like this:

+7+4

equals to 7+4

equals to 11!

Answer:

  (a)  No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Step-by-step explanation:

Build times are 4 hours for a child's bike and 6 hours for an adult's bike. The number of build hours cannot exceed 120. This gives the first inequality:

  4c +6a ≤ 120

Test times are 4 hours each. The number of test hours cannot exceed 100. This gives the second inequality:

  4c +4a ≤ 100

This pair of inequalities matches choices A and C.

When we use c=20 and a=6, these become ...

  4(20) +6(6) = 116 ≤ 120 . . . true

  4(20) +4(6) = 104 ≤ 100 . . . false

The order cannot be built because the test time constraint cannot be met. This matches choice A.

Answer:

3/2

Step-by-step explanation:

slope formula is

y2 - y1 / x2 -x1 = m

so now we just plug in our coordinates.

-4 - 2 / -1 - 3 = -6 / -4 = 3/2

Answer:

the diameter of the circle is ⅓ of the height

so the radius is 1/6 of the height

the area of the flag is 1*1.5 of the height

(we need to consider this)

pi*(1/6)² / 1.5

= 0.058177

so the percentage is

5.82 %

So, the required percentage is  [tex]5.81\%[/tex].

To understand the calculations, check below.

The area of the disk is defined as the ‘ measure of surface ‘ surrounded by the round edge (circumference) of the disk. The area of a disk can be derived by breaking it into a number of identical parts of disk as units — calculating their areas and summing them up till the disk is reformed.

That is [tex]Area=\pi \frac{d^2}{4}[/tex]

Let the width and the length of the flag be [tex]2x[/tex] and [tex]3x[/tex] respectively.

So, the diameter of the gold-colored disk will be [tex]\frac{2x}{3}[/tex]

Now, by using the above formula the area of the gold disk will be,

[tex]\pi \frac{d^2}{4}=\pi\times\frac{4x^2}{4\times 9} \\ =\frac{\pi x^2}{9}[/tex]

And the area of the flag will be,

[tex]Area=l\times b\\=2x\times 3x\\=6x ^2[/tex]

So, the required percentage is,

[tex]\frac{(\frac{\pi x^2}{9} )}{6x^2} \times 100=\frac{\pi}{54}\times 100\\ =5.81\%[/tex]

Answer:

Remember that tan=y/x from your notes from module 4.

Step-by-step explanation:

Refer to the unit circle to see the relationship between x and y at that angle, it is -1. Now you can set up your equation of tan=1/x and solve for x.

For all the problems in this section you can set up an equation where tan=y/x, sin = y/h, and cos=x/h. Then using your equation you can solve for whatever number is missing.

Answer:

The horizontal asymptote represents the terminal population of the trout.

Step-by-step explanation:

The horizontal asymptote of the given rational function is the limit of [tex]p(t)[/tex] when [tex]t \to +\infty[/tex]. That is:

[tex]\lim_{t \to \infty} p(t) = \lim_{t \to \infty} \frac{150\cdot t + 100}{0.04\cdot t + 1}[/tex] (1)

Then, we apply the concept of limits for rational-polynomial functions:

[tex]\lim_{t \to \infty} \frac{\frac{150\cdot t}{t} + \frac{100}{t}}{\frac{0.04\cdot t}{t} + \frac{1}{t} }[/tex]

[tex]\lim_{t \to \infty} p(t) = 3750[/tex]

The horizontal asymptote represents the terminal population of the trout. In this case, the terminal population of the trout is 3750.

√250 = √(25 * 10) = √(5^2 * 10) = √(5^2) * √10

√(-300) = √(-1 * 3 * 100) = √(-1 * 3 * 10^2) = √(-1) * √3 * √(10^2) = i * √3 * 10

… = 10i √3

=>   -a = 10 and b = 3   =>   a = -10 and b = 3

=>   a - b = -10 - 3 = -13

Answer:

0.1739 = 17.39% probability of a successful call.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The odds of making a sale on a single call are 4 to 19.

This means that in 4 + 19 = 23 calls, 4 are successful.

What is the probability of a successful call?

[tex]p = \frac{4}{23} = 0.1739[/tex]
