Answer:
the diameter is twice the circle radius, or 20
Step-by-step explanation:
Recall that the radius is half the diameter <=> the diameter is twice the radius. In this problem we need to find the radius first, then multiply it by 2 to obtain the diameter.
We need to determine the distance between the center of the circle Q(6, -4) and the point R(14, 2) on the circle.
The Pythagorean Theorem applies here. Going from Q to R, x changes from 6 to 14, or 8 units, which is the horizontal leg of a right triangle, and y changes from -4 to 2, or 6 units. Thus, according to the Pythagorean Theorem, the length of the hypotenuse of this triangle is
r = √(6² + 8²) = √100 = 10
and so the diameter is twice that, or 20.

What is the equation of the line that passes through the point (-6,7) and has a slope of -5? Write the equation in slope intercept form
Answer:
y = -5x - 23
Step-by-step explanation:
Write it in point - slope form:
y - 7 = -5(x + 6)
rearrange:
y - 7 = -5x - 30
y = -5x - 23
Identify a transformation of the function ƒ(x) = x^2 by observing the equation of the function g(x) = (x – 1)^2
Answer:
f(x) is translated 1 units left to give g(x)
Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex]
[tex]g(x) = (x - 1)^2[/tex]
Required
How does f(x) transform to g(x)
[tex]f(x) = x^2[/tex]
When translated by b units left, it gives:
[tex]g(x) = f(x - b)[/tex]
In this case:
[tex]b = 1[/tex]
So:
[tex]g(x) = f(x - 1)[/tex]
If [tex]f(x) = x^2[/tex], then
[tex]f(x - 1) = (x - 1)^2[/tex]
Hence:
[tex]g(x) = (x - 1)^2[/tex]
This implies that; f(x) is translated 1 units left to give g(x)

Describe the pattern, write the next term, and write a rule for the nth term of the sequence,
-15,-24,-33,-42
Please show work
Step-by-step explanation:
Next term is - 51
Use formula Tn=a+(n-1)d
a=the first term of the sequence which is - 15
d=the difference between the terms which is - 9
Substitute
Tn=-15+(n-1)(-9)
Tn=-15+9-9n
Tn=-9n-6
From this you will be able to generate all the terms in the pattern
If they say determine the 50th term just substitute 50 by n
Tn=-9(50)-6
Tn=-450-6
Tn=-456

Sarah hiked a path that took her from 34 feet below sea level to 52 feet above sea level. What was the change in her elevation?
Answer:
18 feet
Step-by-step explanation:
52 - 34 = 18
Answer:
18
Step-by-step explanation:
52 - 34 = 18 because she went 34 down so that will be a -34 and then she went 52 up and 52 is a positive number so it really is negative -34 + 52 = 18

-3(y+4)+4y
Please ANSWER FAST!!!!!
Answer: y-12
Step-by-step explanation:
-3(y+4)+4y
first distribute teh -3 to the y and the 4, so you get -3y and -12. Then combine like terms. -3y-12+4y, add the -3y and 4y, you get y. So the answer is y-12.
Answer:
y = 12
Step-by-step explanation:
here's your solution
=> -3(y + 4) + 4y = 0
=> -3y -12 +4y = 0
=> y -12 = 0
=> y = 12

A. 134 is the mode, correct, repeated 5 timesB. 111 is appears 3 times, incorrect , this number is not part of data setC. There are more data values between 130 and 139, correct, there are 8 of themD. There are 20 data values, incorrect , there are 23Line segment JL is an altitude in triangle JKM. Triangle K J M is shown. Angle K J M is a right angle. An altitude is drawn from point J to point L on side K M to form a right angle. The length of K J is 13, the length of J L is 5, and the length of J M is 8. Which statement explains whether JKM is a right triangle? Round measures to the nearest tenth. JKM is a right triangle because KL + LM = 15.3. JKM is a right triangle because KL + LM = 18.2. JKM is not a right triangle because KL + LM ≠ 15.3. JKM is not a right triangle because KL + LM ≠ 18.2.
Answer:
JKM is not a right triangle because KL + LM ≠ 15.3.
Step-by-step explanation:
Given
[tex]JK = 13[/tex]
[tex]JL = 5[/tex]
[tex]JM = 8[/tex]
Required
Determine if JKM is right-angles or not
Calculate length KL using Pythagoras theorem.
[tex]JK^2 = JL^2 + KL^2[/tex]
[tex]13^2 = 5^2 + KL^2[/tex]
Collect like terms
[tex]KL^2 = 13^2 - 5^2[/tex]
[tex]KL^2 = 144[/tex]
[tex]KL = 12[/tex]
Calculate length LM using Pythagoras theorem.
[tex]JM^2 = JL^2 + LM^2[/tex]
[tex]8^2 = 5^2 + LM^2[/tex]
Collect like terms
[tex]LM^2 = 8^2 - 5^2[/tex]
[tex]LM^2 = 39[/tex]
[tex]LM = \sqrt{39[/tex]
[tex]LM = 6.2[/tex]
[tex]KM = KL + LM[/tex]
[tex]KM = 12 + 6.2[/tex]
[tex]KM = 18.2[/tex]
If JKM is right-angled, then:
[tex]KM^2 = JK^2 + JM^2[/tex]
[tex]KM^2 = 13^2 + 8^2[/tex]
[tex]KM^2 = 233[/tex]
[tex]KM = \sqrt{233[/tex]
[tex]KM = 15.3[/tex]
[tex]15.3 \ne 18.2[/tex]
i.e
[tex]KL + LM \ne 15.3[/tex]
Hence: JKM is not right-angled

C-JKM is not a right triangle because KL + LM ≠ 15.3

Shawn erned 5 dallors an hour mowing lawns pluse 10 welkly allounce from his parents what minmin number of hours he needs to mow in order to have enuf money to buy 75 dallars par of basketball sheows
Answer:
13 hours
Step-by-step explanation:
Since Shawn mows lawns at a rate of 5 dollars an hour, if he mows for t hours, he earns 5t dollars. Also, he gets 10 dollars weekly allowance from his parents. Thus, the total amount he earns per week is thus 10 + 5t.
Since he needs to earn enough to buy 75 dollars pair of basketball shoes, the amount he earns must equal the price of the shoes. So,
10 + 5t = 75
We now solve for t to find the amount of hours if takes him to earn enough to buy the shoes.
So,
10 + 5t = 75
Subtracting 10 from both sides, we have
10 - 10 + 5t = 75 - 10
5t = 65
dividing both sides by 5, we have
t = 65/5
t = 13 hours
So, it takes Shawn 13 hours to earn enough to buy the shoes.
