A teacher instructed her students to draw an isosceles triangle that has at least one angle that
measures 75° and exactly one side that measures 12 centimeters.
Using the teacher's instructions, how many different triangles can be drawn that have the same
angle and side measures? Enter your answer in the box.
The number of different triangles that can be drawn that have the same angle and side measures will be 2.
What is an isosceles triangle?It should be noted that an isosceles triangle simply means a triangle that has two sides that are of equal length.
In this case, the number of different triangles that can be drawn that have the same angle and side measures will be 2. The angle is 75° and side length is 12cm.

(4, 5)remain constant and increaseg(x) exceeds the value of f(x)What is Slope and curve?a) The slope of the curve g(x) roughly matches that of f(x) at about x=4. Above that point, the curve g(x) is steeper than f(x), so its average rate of change will exceed that of f(x). An appropriate choice of interval is (4, 5).
b) As x increases, the slope of f(x) remains constant (equal to 4). The slope of g(x) keeps increasing as x increases. An appropriate choice of rate of change descriptors is (remain constant and increase).
c) The curves are not shown in the problem statement for x = 8. The graph below shows that g(x) has already exceeded f(x) by x=7. It remains higher than f(x) for all values of x more than that. We can also evaluate the functions to see which is greater:
f(8) = 4·8 +3 = 35
g(8) = (5/3)^8 ≈ 59.54 . . . . this is greater than 35
g(8) > f(8)
d) Realizing that an exponential function with a base greater than 1 will have increasing slope throughout its domain, it seems reasonable to speculate that it will always eventually exceed any linear function (or any polynomial function, for that matter).

please help!
Answer:
68
Step-by-step explanation:
The shape is 5 sides polygon.
Sum of interior angles of a 5 sided polygon = 540,
7x + 4 + 8x + 3 + 4x + 8 + 10x - 4 + 6x + 4 = 540
7x + 8x + 4x + 10x + 6x + 4 + 3 + 8 + 4 - 4 = 540
35x + 4 + 3 + 8 = 540
35x + 15 = 540
35x = 540 - 15
35x = 525
Divide 35 on both sides,
x = 525 / 35
x = 15
Angle R = 4x + 18
Substitute the value of x,
Angle R = 4 ( 15 ) + 8
= 60 + 8
Angle R = 68

To find out whether the circle will be opened or closed, look at the sign. If the sign is "<" or ">", then the circle will be open. If the sign is either "≤" or "≥", then the sign will be closed.
To decide if the arrow goes right or left, again, look at the sign. If the arrow is going left, then that means x is less than whatever value the circle is at. If the arrow is going right, then x is greater than whatever value the circle is on.
Using this information, you can figure out which inequality matches each number line.

Use the image above to identify and explain the relationship between the segments and circles A and B. In your
explanation, be sure to include specific vocabulary and definitions for the relationships.
PS
Answer:
Step-by-step explanation:
From the given figure, it can be seen that there are two circles with centers A and B respectively. The circle with the center A is larger in size than the circle with center B. Points P, Q and E lie on the surface of the circle having center A and R, S, C and T points lie on the circle having center B.
One tangent passes from the point Q of the one circle to the point T of the another circle and the other tangent passes from point R of the smaller circle to the point E of the larger circle. These two tangents intersects each other outside both the circle. There is another tangent which passes from the point C of the smaller circle to a point D lying outside the circle.

Based on her past experiences, a homeowner estimates that appliances lose 25% of their resale value each year. If her estimate is accurate, how much will an appliance currently valued at $1,500 be worth in 8 years?
Using an exponential function, it is found that an appliance currently valued at $1,500 will be worth $150.17 in 8 years.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, we have that:
The appliance is currently valued at $1,500, hence A(0) = 1500.It loses 25% of their resale value each year, hence r = 0.25.Thus, the equation is given by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 1500(1 - 0.25)^t[/tex]
[tex]A(t) = 1500(0.75)^t[/tex]
In 8 years, the value will be given by:
[tex]A(8) = 1500(0.75)^8 = 150.17[/tex]

Answer:
11
Step-by-step explanation:
Perimeter is figured out by adding all 4 sides.
Width of 11 + width 11 + length 15 + length 15 = 52
And the length of 15 is 4 more than the width of 11
52% of 1000 registered voters intend to vote for Steven Collins for mayor. Based on a 95% confidence interval, can we assume that Steven Collins will win the election if all votes are cast for either him or his opponent, Eric Camden?
A. Cannot be determined as samples cannot reliably be used to estimate population parameters
B. No, since the confidence interval includes values less than 50%, his opponent may get more votes
C. Yes, 52% is a majority of the votes
D. No, sampling variation causes all confidence interval conclusions to be questionable.
Using the z-distribution, it is found that the correct option regarding the question in the problem is given by:
B. No, since the confidence interval includes values less than 50%, his opponent may get more votes.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
In this problem, the parameters are given as follows:
[tex]\pi = 0.52, n = 1000[/tex]
Hence, the bounds are given by:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 - 1.96\sqrt{\frac{0.52(0.48)}{1000}} = 0.489[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 + 1.96\sqrt{\frac{0.52(0.48)}{1000}} = 0.551[/tex]
The lower bound is below 0.5, hence option B is correct.

to go to the corner diagonally opposite
from where she is standing. How
much shorter is it if she cuts across the
diagonal instead of walking around
the perimeter of the field? Round your
answer to the nearest tenth.
The distance between the diagonal and the the perimeter of the field is given by D = 229.2 m
What is the diagonal of a rectangle?The diagonal of a rectangle is calculated by the formula
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
Miranda is standing at the corner of a 70 m by 110 m soccer field.
Let the dimensions of the rectangle be 70m x 100m
Now , the length of the diagonal is D
And , from the Pythagoras theorem ,
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
D = √ ( 70 )² + ( 110 )²
D = 130.8 m
Now , the perimeter of the rectangle is P = 2 ( 70 + 110 ) = 360 m
And , walking around the perimeter of the field
Now , by cutting across the diagonal instead of walking around the perimeter of the field, Miranda can save approximately 360 m - 130.8 m ≈ 229.2 m.
Hence , the diagonal of the rectangle is 130.8 m

Find the equation of the line shown
Answer:
y = 2x
Step-by-step explanation:
Use y = mx + b to write an equation. The y-intercept is zero. This is where the line crosses the y -axis, kind of the "starting point" So in the equation the b is a zero.
You can grab a couple points from the line to do a calculation for slope. BUT, you can actually SEE the slope on this line and save yourself the calculation. Starting from zero, see that you go UP 2 and OVER 1 to get to the next point. UP2OVER1 gets you to the next point and the next point. UP2OVER1 is the slope 2/1, which is 2, which is the m in the equation.
y = 2/1 x + 0
y = 2x + 0
y = 2x
**in case you have to show a calc for slope. Grab two points and do y-y, put that on top and then x-x and put that on the bottom.**

Another pair of coordinates that could be the missing ordered pair, (x,y) in this set is (1, 0)
Linear functionsLinear functions are functions that have a leading degree of one,
Given the coordinate points ((-2,-3), (0,-2), (2, -1), (x, y)}, we need to determine the missing coordinate points
Since the x-coordinates has a difference of 2, hence the missing x-coordinate is given as:
x = -1 + 2
x = 1
For the y-coordinate
