Find Distance (4,6) (-4,-3)
Answer:
[tex]\sqrt{145}[/tex]
Step-by-step explanation:
The distance formula states that the distance between two points [tex](a,b)[/tex] and [tex](c,d)[/tex] is [tex]\sqrt{(a-c)^2+(b-d)^2}[/tex].
The two points we have are [tex](4,6)[/tex] and [tex](-4,-3)[/tex]. Plugging these numbers into the distance formula, we have
[tex]\sqrt{(4-(-4))^2+(6-(-3))^2[/tex].
Simplifying with order of operations, first using the distributive property, gives
[tex]\sqrt{(4+4)^2+(6+3)^2[/tex].
Squaring and adding gives
[tex]\sqrt{(4+4)^2+(6+3)^2}=\sqrt{8^2+9^2}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\sqrt{64+81}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{\sqrt{145}},[/tex]
which is the answer in simplest form. This also rounds to about 12.04.

A large school district found that 88 of 100 randomly selected students at East High School had internet access
at home. A separate random sample from West High showed 79 of 100 students had internet access at home.
Administrators used those results to make a 90% confidence interval to estimate the difference between the
proportion of students at each school who have internet access at home (PE - Pw). The resulting interval was
approximately 0.09 0.086. They want to use this interval to test H, : PE = Pw versus H : PE + Pw at
the a = 0.10 significance level. Assume that all conditions for inference have been met.
Based on the interval, what do we know about the corresponding P-value and conclusion at the a=0.10
level of significance?
It can be deduced that the p-value is less than the level of significance.
What is a level of significance?It should be noted that the level of significance simply means the measure of the strength of the evidence that's is present in a sample before the null hypothesis is rejected.
From the complete question, the confidence interval is a given as (0.004, 0.176). In this case, the p-value is less than the level of significance and they should conclude that there's a difference between the proportions.

Prove that the value of the expression
(3^5-3^4)(3^3+3^2) is divisible by 24
Answer:
243
Step-by-step explanation:
(3^5 – 3^4) (3^3 + 3^2)
= (243 – 81) (27 + 9)
= (162) (36)
= 5832
24 = 8*3
because 832 can be divided by 8 and 5+8+3+2 = 18 is divisible by 3,
5832 is divisible by 24

A star is cut from 1 cm grid paper.
What is the approximate perimeter and area of the
star?
The perimeter is about
cm.
The area is about
cm2
Answer:
The answer is 16 cm
Step-by-step explanation:
If the area was 16cm^2 before, then each side was 4 cm long since each side of a square is equal, and the area for a square is the length of the sides squared. The square root of 16 is 4, so that is why the sides were 4 cm. When you make each side 1 cm shorter, they're now all 3 cm. 3^2 is 9, so the new area is 9 square centimeters.

Which equations represent an indirect variation relationship whit a constant of variation equal to -4? Select ALL correct answers
A) xy = -4
b) y = -4/x
c) y = x/-4
d) y = -4x
The equations that represent an indirect variation relationship with a constant of variation equal to -4 are y = -4/x and xy = -4
Direct and indirect variationAn indirect variation is also known as the inverse variation
If the variable y is indirectly proportional to x , this is expressed as:
y = k/x
where
k is the variation constant
If the variation constant is -4, then;

Kevin works two part-time jobs and wants to earn a total of at least $504 per week. He earns an
average of $12 per hour delivering food and $14 per hour working retail
A.) Write the inequality representing the scenario
B.) Graph the inequality
Kevin earning at least $504 implies that he wants to earn $504 or more
The inequality representing the scenario is [tex]12x + 14y \ge 504[/tex]
How to interpret the scenario?The given parameters are:
Earnings = At least $504
Food delivering = $12 per hour
Retail = $14 per hour
Represent the number of hours delivering food with x, and the retail work with y.
So, the earning is:
Earning = 12x + 14y
The earning is at least $504.
So, we have:
[tex]12x + 14y \ge 504[/tex]

Answer:
Step-by-step explanation:
One
√15 / ∛15 = 15^(1/2 - 1/3) = 15^(1/6)
When you divide numbers that are the same base but different powers, the following rule applies
base^(numerator power - denominator power)
Two
15^(1/2 + 1/4)
15^(3/4)
When you multiply 2 numbers with the same base and different powers you raise the base by the sum of the powers.
