The distance between points (- 3, 0, -7) and (- 8, - 9, - 11) is approximately 11.1 units and the midpoint is (x, y, z) = (- 5.5, - 4.5, - 9).
What is the distance between the two points and what is the midpoint of the line segment?
First, we find the vector between the two points by vector sum:
[tex]\vec r = (-8, -9, - 11) - (- 3, 0, -7)[/tex]
[tex]\vec r = (- 5, - 9, - 4)[/tex]
The distance between the two points is found by the following Pythagorean expression:
[tex]d = \sqrt{(-5)^{2}+(-9)^{2}+(-4)^{2}}[/tex]
d ≈ 11.1
And the midpoint is found by linear algebra:
[tex]\vec m = 0.5\cdot (-3, 0, -7) + 0.5 \cdot (-8, -9, - 11)[/tex]
[tex]\vec m = (- 1.5, 0, - 3.5) + (- 4, - 4.5, -5.5)[/tex]
[tex]\vec m = (- 5.5, - 4.5, - 9)[/tex]
The distance between points (- 3, 0, -7) and (- 8, - 9, - 11) is approximately 11.1 units and the midpoint is (x, y, z) = (- 5.5, - 4.5, - 9).

Ten cards numbered 1-10 are placed in a hat.What is the probabiliy of randomly drawing a card with an even number then a card with a number equal to five if the firdt card iis replaced
Answer:
1/ 20
Step-by-step explanation:
Given :
Cards = {1,2,3,4,5,6,7,8,9,10}
Even number = {2,4,6,8,10}
Probability (drawing an even number) :
Number of even / total. Number of cards
5 / 10 = 1/2
Card with number, 5 :
P(card numbered 5) = 1/10
Since they are independent events :
P(even number) * P(card numbered 5)
1/2 * 1/10 = 1/20
The average diameter of a tree is measured over time. The equation y = 3/4x, where x is time in years and y is the
diameter in inches, models this relationship.
What is the predicted diameter, in inches, of the tree after 12 years?
Answer:
The predicted diameter of a tree after 12 years is 9 inches.
Step-by-step explanation:
The average diameter of the tree is represented by [tex]y = \frac{3}{4}\cdot x[/tex]. The predicted diameter of the tree after 12 years is determined by evaluating the linear function at [tex]x = 12[/tex]. That is:
[tex]y = \frac{3}{4}\cdot (12)[/tex]
[tex]y = 9[/tex]
The predicted diameter of a tree after 12 years is 9 inches.
Stewart has a home-based business putting on children’s parties. He charges $60 to design the party and then $6.00 per child. Write a function rule that relates the total cost of the party to the number of children n.
f(n) = 6 + 60n
f(n) = 6n – 55
f(n) = 60 + 6n
f(n) = 6 – 55n
Answer:
f(n) = 60 + 6nStep-by-step explanation:
numbers of students = n
party decoration charge = 60
per child cost = 6
so, therefore
f(n) = 60 + 6n
MARK ME AS BRAINLISTPLZ FOLLOW MEAnswer: A. f(n) 60 + 6n
60 is constant
6 per child is variable
Let c = number of children
total cost = 60 +6c
Step-by-step explanation: i got it from somebody else's brainly
If there are n children, and each additional child who joins will add another $6 to the cost, then the cost due to the number of children will be 6n. We also have the fixed cost of $60, no matter how many children join. Therefore, we add up these costs to get Cost = f(n) = 60 + 6n.

The hypotenuse of the right triangle is 5y inches long. The lengths of the legs are x + 8 and x + 3 inches. If the perimeter of the triangle is 60 inches and the length of the hypotenuse minus the length of the shorter leg is 10 inches, how many inches long is the hypotenuse?
Answer:
25
Step-by-step explanation:
The perimeter of triangle is equal to the sum of all sides of triangle
then:
5y + (x+8) + (x+3) = 60
5y + 2x +11 = 60
5y +2x = 49 ..............................................................(1)
the hypotenuse - shorter leg = 10
hint ( shorter leg ) = x+3
then
5y - (x + 3 ) = 10
5y - x - 3 = 10
5y - x = 13 .................................................... (2)
from 1 and 2
5y +2x = 49 .................................................................. (3)
5y - x = 13 (multiply both sides by 2 )
10y - 2x = 26 ..................................................................(4)
by sum 3 and 4
15y = 75
then y = 75/15 = 5
then hypotenuse = 5y = 5 x 5 = 25
Answer:
5
Step-by-step explanation:
Rewrite the equation 2x + 3y = 6 in slope-intercept form.
3y = -2x + 6
y= -2x+6
y= - 2/3 x+2
y = 2x+6

Solve for x:
logx - log(x+5) = log2
need step-by-step solution
Answer:
no solution
Step-by-step explanation:
logx - log(x+5) = log2,
logx = log2 + log(x + 5),
Remember that logs of the same base can be added together by multiplying their arguments:
log(x) = log [(x + 5)*2]
We cancel the logarithms by taking the exponents of both sides:
x = (x + 5)*2,
x = - 10
But x = - 10 makes the value undefined, so we say no solution.

Answer: Choice A) The linear equation, aka straight line
Explanation:
The end behavior is determined by the ratio of the leading terms. This is because for large x values, the leading terms "drown out" (so to speak) the weight of the other terms.
We divide the leading terms 10x^3 over 2x^2 to get 5x. So as x gets really large, in either the positive or negative direction, the tail end portions will start to approach y = 5x. This is the slant or oblique asymptote. The end behavior or y = 5x has the left side going down, while the right side is going up. The same applies for the f(x) function as well.

Which statement best describes the domain of the function represented in the graph?
Given:
The graph of a function.
To find:
The correct statement for the domain of the given function graph.
Solution:
Domain is the set of x-values for which the function is defined or it is the set of input values.
From the given graph it is clear that it is a linear function with end points (1,2) and (9,14).
So, the given function is defined for [tex]1\leq x\leq 9[/tex]. Here 1 and 9 are including in the set of x-values.
Therefore, the correct option is C, i.e., [tex]1\leq x\leq 9[/tex] or x between 1 and 9, inclusive.

Answer:
8 13/28 or as a decimal: 8.46
Step-by-step explanation:
Rewrite the sum:
(4+3)+(5/7+3/4)
Add the numbers 4+3:
7+(5/7+3/4)
Add the fractions:
7+41/28
Convert the improper fraction into a mixed number:
7 + 1 13/28
Write the mixed number as a sum of the whole number and the fractional part:
7+1+13/28
Add the numbers 7+1 and then there is your answer!
8 13/28
If your paper, quiz, homework, etc says decimal form or alternative form then the decimal form is 8.46 and the alternate form is 237/26. But 8 13/28 cannot be reduced any lower.
