Answer:
1. y-25=5/2(x-14)
2. [tex]y=\frac{5}{2}x-10[/tex]
3. 5x-2y=20
Step-by-step explanation:
first, find the slope, m.
slope = rise/run = (75-25)/(34-14)= 50/20 = 5/2
1. point slope form: y-25=5/2(x-14)
2. [tex]y=\frac{5}{2}x-10[/tex]
3. switch the y to the right side: (5/2)x-y-10=0 --> (5/2)x-y=10
5x-2y=20

Answer:
2√73 or 17.09 inches
Step-by-step explanation:
The small red square at the corner of the triangle symbolizes that the triangle is a right triangle. Therefore, to find the hypotenuse of the triangle, we can use the Pythagorean Theorem: a² + b² = c²
a = 6
b = 16
c = ?
Plug these values into the equation.
(6)² + (16)² = c²
Evaluate the exponents.
36 + 256 = c²
292 = c²
Take the square root of both sides to find c.
√292 = √c²
17.09 ≈ c
This is your answer.
You can also simplify the radical without using decimals.
4 • 73 = 292
Therefore,
√4 • √73 = √292
Which also means,
2•√73 = √292
So your answer is: 2√73
Hope this helps!
Answer:
We use the pythagorean theorem a²+b²=c² and in this question
a = 6
and
b = 16
so
36 + 256 = c²
so
c² = 292 so now we take the square root of it to get [tex]\sqrt{292}[/tex]
Hope this helps!

Triangle A'B'C' is the image of ABC under a dilation with a scale factor of 2.
What length of segment A'B?
The length of segment A'B' from the triangle A'B'C' is 6 units.
Given that, triangle A'B'C' is the image of ABC under a dilation with a scale factor of 2.
In the given triangle ABC, AB=3 units
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
2=Dimensions of the new shape/3
Dimensions of the new shape=6 units

During week 1 of a recycling drive, the fifth grade class recycled 9
pounds of glass and 123 pounds of newspaper. During week 2, the
fifth grade class recycled 8 pounds of glass and 13 pounds of
newspaper. How many more pounds of newspaper than glass did
the class recycle?
Answer:
119 pounds
Step-by-step explanation:
Glass :
1) 9 pounds
2) 8 pounds
9 + 8 = 17 pounds
Newspaper
1) 123 pounds
2) 13 pounds
123 + 13 = 136 pounds

If 12 + 6x is 20 more than 16, what is
the value of 12x?
Answer:
12x = 48
Step-by-step explanation:
Translating the word problem into an algebraic equation, we have;
12 + 6x = 16 + 20
12 + 6x = 36
6x = 36 - 12
6x = 24
x = 24/6
x = 4
To find 12x;
12x = 12 * 4 = 48

In 2008, the world record for swimming the 50 meter freestyle event was 21.34 seconds. Supposing the athlete swam at a constant rate what was his speed? Round your answer to the nearest hundredth m/s.
Answer:
Speed of swimmer = 2.34 m/s (Approx.,)
Step-by-step explanation:
Given:
Distance covered in world record swimming = 50 meters
Time taken by free style swimmer = 21.34 seconds
Find:
Speed of swimmer
Computation:
Speed = Distance / Time taken
So,
Speed of swimmer = Distance covered in world record swimming / Time taken by free style swimmer
Speed of swimmer = 50 / 21.34
Speed of swimmer = 2.34 m/s (Approx.,)

A century ago, the average height of adult women in the United States was 63 inches. Researchers believe that the average might be greater today. A random sample of 40 adult women was selected from the population. The sample had mean 64.2 inches and standard deviation 2.9 inches. Assuming all conditions for inference are met, the researchers will perform an appropriate hypothesis test to investigate their belief.
Required:
What is the correct test statistic for the hypothesis test?
Answer:
t= 64.2-63 / 2.9/ sqrt 40
Step-by-step explanation:
Got it right on AP Classroom
There is a 0.18 probability of obtaining a sample mean height of exactly 64.2 inches from a population whose mean height is 63.7 inches.
What is the null hypothesis?The null hypothesis in inferential statistics states that two possibilities are identical. The null hypothesis states that the observed difference is purely random. It is feasible to calculate the probability that the null hypothesis is correct using statistical testing.
1. C) H0: u = 63.7 in. versus H1: u > 63.7 in.
the null hypothesis state that over the years the mean height is 63.7in. the alternative hypothesis will be if the mean height is greater than 63.7
2. z = (variate - mean)/ (standard deviation/
Z = (64.2 - 63.7)/ (20/roots 45) =0.17
meaning there is
B. There is a 0.18 probability of obtaining a sample mean height of exactly 64.2 inches from a population whose mean height is 63.7 inches.
3. if the level of significance is 0.05 or between 0.05 and 0.01, i.e. the confidence level is 95% or between 95% and 99%, the results are considered to be probably significant, i.e. the results are probably correct,
Therefore, the alternative hypothesis is correct

Answer:
B. x = 7; AB = 9, AC = 12
Step-by-step explanation:
12/4 = (x + 2)/(x - 4) (similar triangles theorem)
3 = (x + 2)/(x - 4)
Cross multiply
3(x - 4) = (x + 2)
3x - 12 = x + 2
Collect like terms
3x - x = 12 + 2
2x = 14
x = 14/2
x = 7
✔️AB = x + 2 = 7 + 2
AB = 9
✔️AC = (x + 2) + (x - 4) = (7 + 2) + (7 - 4)
AC = 9 + 3
AC = 12
Express as a difference: a+5
The expression expressed as a difference is (a - 2) - (-7).
We have,
We can express a + 5 as a difference by subtracting a suitable term from it.
One way to do this is to subtract 2 and add 2, like this:
a + 5 = a + 5 - 2 + 2 (adding and subtracting 2)
= (a - 2) + 7 (rearranging)
Now,
We can express a + 5 as the difference between a - 2 and -7, like this:
a + 5 = (a - 2) - (-7)
Thus,
The expression expressed as a difference is (a - 2) - (-7).
