Answer:
|x - 89| ≤ 5
Step-by-step explanation:
Here the range is 84 to 94 ft, with the midpoint being 89 and the greatest variation from the midpoint being ±5.
We adapt |x| ≤ a as follows: replace x with 'x - 89' and a with 5:
|x - 89| ≤ 5
It is customary to regard '89' as the 'center' of the solution interval and 5 as the 'maximum difference' or 'radius' separating x from this center.
Find the midpoint of CD when
C (-2, -1) and D (4, 3).
Answer: (1, 1)
Step-by-step explanation:
Midpoint formula: [tex](\frac{x1+x2}{2} ,\frac{y1+y2}{2} )[/tex]
(x1, x2)=(-2, 4)
(y1, y2)=(-1, 3)
-----------------------------------------
[tex](\frac{x1+x2}{2} ,\frac{y1+y2}{2} )[/tex]
=[tex](\frac{-2+4}{2} ,\frac{-1+3}{2} )[/tex]
=[tex](\frac{2}{2} ,\frac{2}{2} )[/tex]
=[tex](1, 1)[/tex]

Determine the rate of change for 3/2x -5/4y = 15
Answer:
-6/5
Step-by-step explanation:
3/2x - 5/4y = 15
-5/4y = -3/2x + 15
multiply each side by (-4/5)
(-4/5)(-5/4y) = (-4/5)(-3/2x + 15)
y = -6/5x - 12
rate of change: -6/5

Please HELP ASAPPPP uts not -3!!!
Answer:
x= 11
Step-by-step explanation:
(7x -1)° + (9x +5)°= 180° (adj. ∠s on a str. line)
7x -1 +9x +5= 180
16x +4= 180 (simplify)
16x= 180 -4 (-4 on both sides)
16x= 176 (simplify)
x= 176 ÷16
x= 11
The sum of the angles on a straight line is 180°

Write a ratio for the following description: Kaleel made three times as many baskets as John during basketball practice. Type your answer in the format: 3:4 with no spaces.
Answer:
3:1
Step-by-step explanation:
hey there,
< We know Kaleel made 3x as many baskets as John.
We're going to make our ratio Kaleel:John.
The answer would be 3:1 because every time John makes 1 basket, Kaleel makes 3 baskets. If John made 2, then Kaleel would make 6, etc...

1/2(-2x - 12) > 7(3 - 4x)
The solution is____
Answer:
x > 1
interval (1,∞)
Step-by-step explanation:
1/2(-2x - 12) > 7(3 - 4x)
-x - 6 > 21 - 28x
-x + 28x > 21 + 6
27 x > 27
x > 27 / 27
x > 1
interval (1,∞)
-x - 6 > 21 - 28x if x = 2
-2 - 6 > 21 -28(2)
-8 > 21 - 56
- 8 > - 35

on a piece of paper, graph y<-3/4x+2. Then determine which answer choice matches the graph you drew.
Answer:
D. Graph D
Step-by-step explanation:
The "y <" tells you two things: (1) shading will be below the line, where y-values are less than those on the line, and (2) the line will be dashed, because the "equal to" case is not included.
Only one graph has a dashed line with shading below: Graph D.
Each school day, Aidon wolks 11 blocks to school after school, he wolks 4 blocks to the library
and 12 blocks home. How many blocks does Aidon wolk in a week? *
e
Answer:
189
Step-by-step explanation:
Aidon walked 11 blocks to begin with than he walks 4 blocks to the library and 12 blocks home. This mean we add 11+4+12=27 and a week has 7 days which means we need to multiply that by 7 which gives us the product of 189.
Also, i double checked
A 2000 kilogram sports car accelerates at a ratr of 30 meters per second squared. The velocity of the car is v=at where a is acceleration in meters per second squaref and t is tome in seconds. The kinetic energy of the car is KE = 1/2 mv^2
Answer:
KE = 900,000t²
Step-by-step explanation:
The formula for calculating the kinetic energy of a body is expressed as KE = 1/2mv² where;
m is the mass of the sport car = 2000kg
v is the velocity of the car
Since v = at
v = 30t
Substituting the given values into the KE formula;
KE 1/2 * 2000 * (30t)²
KE = 1000*900t²
KE = 900,000t² Joules where t is the time measured in seconds
Answer:
KE = 900,000t²

Answer:
a. Maurice walked farther.
b. 0.62 m
Step-by-step explanation:
Maurice
4.1 × 1.8 = 7.38 miles
Junnie
2.5 × 3.2 = 8 miles
This shows that Junnie walked more than Maurice.
8 - 7.38 = 0.62
Junnie walked 0.62 m more than Maurice
Which number is irrational, and integer, and a real number A) -4/2 B) there is no such number
Answer:
Step-by-step explanation:
real number can be irrational or integer.
otherwise there is no number which can be irrational,integer and real (all together)
Answer: The answer is B) there is no such number.
Step-by-step explanation:
So we have to find which number is irrational, and integer, and a real number. Let's examine the problem closely:
- irrational means not rational and cannot be represented by a simple fraction (like pi )
- an integer means a number that can be written without a fractional component ( -1, 2, 0, -10000 )
- and a real number means that it is not imaginary ( like 2i, [tex]\sqrt{-1}[/tex] )
And our choices here are:
- -4/2
- there is no such number
Let's take a look at -4/2. This number is a fraction, but it can be simplified down to -2/1, which is an integer. -2 is a real number, not an imaginary number. But, -2 is not irrational, because as it just was shown here, it CAN be represented by a fraction. So, since only two out of the three criteria are true, then we have to consider choice B.

A research company wants to test the claim that a new multi vitamin helps improve short term memory state the objective of the experiment suggest a population determine the experimental and control groups and describe a simple procedure
Answer:
To test the effects of the multi-vitamin, we must test it on people with short-term memory loss. So the population should be people with short-term memory loss. The independent variable is the multi-vitamin and the dependent variable is the short term memory state of the people being tested. A control group can consist of people with short-term memory loss NOT being treated by the multi-vitamin.

Give an example of an odd function and explain algebraically why it is odd.
An odd function is a function of a form [tex]y=x^n[/tex] where n is an odd number.
Some examples would be functions:
[tex]y=x,y=x^3,\dots[/tex].
A formal definition of odd function is the following.
(Algebraic proof).
Let [tex]f:\mathbb{R}\to\mathbb{R}[/tex] (real function).
The function is odd if the below equation is true for all x and -x for which the function is defined:
[tex]f(x)=-f(-x)[/tex].

I’m a constant function. There are two possible ways to write me; one way being slope-intercept form and the other being constant form
(I don’t really understand what this question is asking)
Answer:
constant function has the same output no matter what are the inputs and it is written in the form : y=b where b is a constant that does not change. the slope of this function always equal to zero.
slope intercept form : y=mx+b ( where m=0)
constant form : y=b ( y equal a constant that does not change)
