Two sides of a triangle and an angle between them are given. Construct the triangle. Does the solution exist for any given angle?
A solution exists for constructing a triangle given two sides and the included angle if the triangle inequality theorem is satisfied
We have to draw a line segment to represent one of the given sides of the triangle.
From one endpoint of the line segment, use a protractor to measure the given angle. Mark this angle on the line segment.
Using a compass, set the compass to the length of the other given side of the triangle.
With the compass centered at the endpoint of the line segment, draw an arc that intersects the angle on the line segment.
Draw a line connecting the endpoint of the line segment to the point where the arc intersects the angle.
This line represents the second side of the triangle.
Finally, draw a line connecting the two endpoints of the sides you have constructed. This line completes the triangle.

20d + 0.7m = 235
Shelly spent $235 to rent a moving van. The equation above shows the relationship
between the number of days she rented the van, d, and the number of miles she drove
the van, m. If she rented the van for 3 days, how many miles did she drive the van?
The number of miles she drove the van for is 250 miles
Solving linear equationsFrom the question, we are to determine the number of miles Shelly drove the van
The given equation which shows the relationship between the number of days she rented the van, d, and the number of miles she drove the van, m is
20d + 0.7m = 235
Now, if she rented the van for 3 days, that is, d = 3
Putting the value of d = 3 into the equation to determine the value of m
We get
20(3) + 0.7m = 235
60 + 0.7m = 235
0.7m = 235 - 60
0.7m = 175
m = 175 / 0.7
m = 250
Hence, the number of miles she drove the van for is 250 miles

Please help me with question 36. I don’t know the answer
Answer:
Period = [tex]\frac{\pi }{4}[/tex]
Amplitude = 4
Step-by-step explanation:
To find the answer, use the form acos(bx - c) + d:
a = -4
b = 8
c = 0
d = 0
The amplitude is the absolute value of a, so:
|a| = |-4| = 4
To find the period, use this equation:
[tex]\frac{2\pi }{b}[/tex]
Replace b with 8 in the formula and solve:
[tex]\frac{2\pi }{8} = \frac{\pi }{4}[/tex] Simplify
So, the period is equal to [tex]\frac{\pi }{4}[/tex]

Simplify the expression. Write your answer as a power.
The simplified expression is
Answer:
Answer = 6^7
Step-by-step explanation:
When multiplying expressions with exponent you add the exponents together. So here you would get 6^13/6^6. However you can simplify this farther since the base (6) is the same. When dividing expressions with exponents you subtract the exponents so the the answer would be 6^7.

Step-by-step explanation:
Experimental probability
Calculated by dividing the number of times an event happens by the total number of trials in an actual experiment.
[tex]\textsf{Experimental Probability} = \dfrac{\textsf{Number of times an event happens}}{\textsf{Total number of trials}}[/tex]
Total number of trials = 10 + 6 + 4 + 8 + 6 + 6 = 40

How to find maximum and minimum values of a parabola
Answer:
Step-by-step explanation:
Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.

f(x) = 3x + 2
What is f(5)?
Answer:
17
Step-by-step explanation:
→ f(x) = 3x + 2
→ f(5) = 3(5) + 2
→ 15 + 2
→ 17 is the answer.
Answer:
F(5) = 17
Step-by-step explanation:
to solve, we just need to plug all values of x into 5 as shown
f(x) = 3x + 2
f(5) = (3*5) + 2
then following the format of PEMDAS (explained at footer) we solve the new equation
f(5) = (3*5) + 2
f(5) = 15 + 2
f(5) = 17
therefor F(5) is equal to 17
The PEMDAS format of solving equations:
the term Pemdas stands for the steps involved in solving an equation

Write a negative function h(x) with a y-intercept at "-4" with one solution
The required negative function h(x) with a y-intercept at "-4" with one solution is x + 4
Intercept of the equationThe y-intercept of an equation is the pint where the x-value of the function is 0, that is;
f(-4) = 0
Since the solution has one solution, hence it will be linear in nature
h(x) = x + 4
This gives the required negative function h(x) with a y-intercept at "-4" with one solution

The diameter of a circle is 42 ft. Find its area to the nearest whole number.
Answer:
5539 or 1764[tex]\pi[/tex]
Step-by-step explanation:
to find the area, we need the radius
The radius(R) is half of the diameter(D)
R = D/2
R = 42/2
R = 21
area of a circle(A) = pi x radius[tex]^{2}[/tex]
A = pi( which most times in a problem, equals 3.14) x 42[tex]^{2}[/tex]
A = 3.14 x 1764
A = 5538.96
A(when rounded) = 5539
In Galton’s height data, the least-squares line for predicting forearm length (y) from height (x) is y = −0.2967 + 0.2738x.
Predict the forearm length of a man whose height is 72 in. Round the answer to three decimal places.
Using the line of best fit, it is found that the prediction of the forearm length of a man whose height is of 72 in is of 19.417 in.
What does the line of best fit state?It states that the predicted forearm length of a person of height x is given by:
y = -0.2967 + 0.2738x.
In this problem, the height is of x = 72 in, hence:
y = -0.2967 + 0.2738(72) = 19.417 in.
