Step-by-step explanation:
What is the midpoint of the line segment with endpoints (-10, 9) (6, -7)
Answer:
here ([tex]x_{1[/tex],[tex]y_{1}[/tex])=(-10,9)
([tex]x_{2}[/tex],[tex]y_{2}[/tex])=(6,-7)
use formula,
(x1+x2)/2,(y1+y2)/2
(-10+6)/2,(9-7)/2
-6/2,2/2
-3,1
Step-by-step explanation:
therefore midpoint of the given two coordinate points is(-3,1)
What is the average rate of change of f(x) on the interval [-3, -1]?
Answer:
To get a more specific answer, you'll need a specific function formula.
Step-by-step explanation:
The average rate of change in a function is the slope of a segment connecting two points on the graph of the function. If a formula (rule) for the function is given, then a graph is not usually necessary.
Example: Given the function [tex]f(x)=x^2[/tex], what is the average rate of change on the interval [tex][-3,1][/tex]?
Find the value of the function at each endpoint.
[tex]f(-3)=9\\f(-1)=1[/tex]
Then find
[tex]\frac{f(-1)-f(-3))}{-1-(-3)}=\frac{1-9}{-1+3}=\frac{-8}{2}=-4[/tex]
The average rate of change in f on the interval is 4.
What is the domain of the function y = l n (x + 2)
A. x < -2
B. x > -2
C. x < 2
D. x > 2
Answer:
Option B.
Step-by-step explanation:
For a function f(x), the domain is the set of all the possible values of x that can be used in the function.
We know that the natural logarithm is only defined for positive real numbers.
So, the function:
Ln(x + 2)
Works always that
x + 2 > 0
So we can just solve this inequality for x, and that will give us the domain of the function.
To isolate x, we just need to subtract 2 in both sides of the inequality.
x + 2 - 2 > 0 - 2
x > - 2
This is the domain of the function.
The correct option is B.
Answer:
b.x>-2

Jeffrey and Marie just had a baby and want to invest money into a bank account to save money for their newborn. The bank account they are looking into yields 6.8% interest each year. If Jeffrey and Marie invest $500, how much money will be in the account when their child's turns 18 years old
Answer:
$1,112
Step-by-step explanation:
6.8% x 500= 34
34 x 18 = 612
612 + 500 = 1112
A ball is thrown into the air with an upward velocity of 12 meters per second. Its height h in meters after t seconds is given by the function h=-16 + 12t + 5. How long will it take the ball to reach its maximum height? What is the ball's maximum height? What is the range of the function? look at the picture as well
Answer:
-16(5/8)^ 2 + 20(5/8) + 6 = 12.25 ft
Step-by-step explanation:
h = -16t^ 2 + 20t + 6 the ball will hit the ground when h = 0
0 = -16t^2 + 20t + 6 factor
0 = ( -8t - 2 ) ( 2t - 3) set each factor to 0
-8t - 2 = 0 and 2t - 3 = 0
-8t = 2 2t = 3
t = -2/8 = - 1/4 sec t = 3/2 sec = 1.5 sec
Max hit will be reached at [ -b / 2a ] sec = -20 / [ 2(-16)] = 20/32 = 5/8 sec
-16(5/8)^ 2 + 20(5/8) + 6 = 12.25 ft

i need help with this
Answer:
A
Step-by-step explanation:
For the first block, you need to multiply a x a x b
3 x 3 x 6 = 54
For the 2nd block, you need to multiply a x a x c
3 x 3 x 12 = 108
Now you need to add both volumes of the blocks
108 + 54 = 162 in^3

Answer:
Step-by-step explanation:
Since we have one angle with an opposite side and another side known, we are dealing with an ambiguous case. There are either
0
,
1
or
2
solutions to this triangle.
We start by determining the measure of

using the law of Sines, since we already know the measure of side

There is only one solution to this triangle, because if it was, then the alternative measure of A would be

−

=

, which when added to

We can now use the measure of angles

D'après la question ci-dessus, on nous dit que:
La boîte à linge de Killian est remplie aux 2/3.
Il utilise un quart de ce qui reste dans le conteneur pour laver ses vêtements.
La fraction de ce qu'il utilisait pour laver ses vêtements =
1/4 sur 2/3

Tim had nine cards, each with a different number from 1 to 9 on it.
He put the cards into three piles so that the total in each pile was 15.
How could he have done this?
Can you find all the different ways Tim could have done this?
All.
Answer:
Tim had nine cards with each having a distinct number from 1-9, meaning no number should be repeated twice while he tried to arrange them in piles while each pile should have a total of 15 when these numbers in the card are added all together.
I would arrange the ways below in rows and columns to make it easier to understand:
Ways Ist Pile 2nd Pile 3rd Pile
1st way: 5, 1, 9 2, 4, 6, 3 7, 8

Function “p” is in the form y=ax^2 + C. If the values of “a” and “c” are both less than 0, which graph could represent “p”?
A. Graph A
B. Graph B
C. Graph C
D. Graph D
Answer:
B
Step-by-step explanation:
Since the value of a is less than 0, the graph of the parabola would be opening downwards. Because of this we can rule out option C. In a quadratic equation, c represents the y-intercept, and, in this case c is negative, meaning the y-intercept is less than 0. Only option B has a downward-opening curve and a y-intercept less than 0, so it is the answer.
Answer:
B. Graph B
