12 - ( 3r + 2 ) = - 7 ( r + 6 )
Answers
Answer:
r = -13
Step-by-step explanation:
Step 1: distribute the signs & terms outside the parenthesis. on the left side, distribute a - sign (same thing as -1) and on the right side distibute -7
12 - (3r) - (+2) = (-7)r + (-7)6
Step 2: algebraically simplify
10 - 3r = -7r - 42
52 = -4r
r = -13

The population of a once very popular city of 250,000 people has been decreasing by 3.5% each year. Write an exponential decay function that represents the population after t years
Answers
3.5 percent of 250000 is 8750, if that’s the amount decreasing each (t) years, you multiply that number by number of years taken into account.
An exponential decay function that represents the population after t years is [tex]\rm f (x) = 250000 (0.965)^t[/tex].
What is an Exponential Function?An exponential function can be represented in the form f(x) = aˣ.
The population of a city was 250,000
Rate of decay is 3.5%
100 -3.5 = 96.5%
The population after t years is represented by the function
[tex]\rm f (x) = 250000 (0.965)^t[/tex]

the sum of 5 and the quotient of 4 and 2
the product of 5 and the quotient of 4 and 2
Answers
According to PEMDAS you have to divide 4 and 2
Which is 2 and 2 + 5 gives you 7
The required answer would be the sum of 5, and 4 is divided by 2 as per the PEMDAS rule which is the correct answer would be option (A)
What is the PEMDAS rule?PEMDAS rule states that the order of operation starts with the calculation enclosed in brackets or the parentheses first. Exponents (degrees or square roots) are then operated on, followed by multiplication and division operations, and then addition and subtraction.
We have been given that expression as
⇒ 5 + 4 ÷ 2
As per the PEMDAS rule,
We have to apply the division operation to terms 4 and 2,
⇒ 5 + 4 /2
⇒ 5 + 2
Apply the addition operation, and we get
⇒ 7
Therefore, the required answer would be the sum of 5, and 4 is divided by 2.

What is the distance between (-8,2)and (6,2)?
Please help me
Answers
Answer:
The distance is 4 units.
Step-by-step explanation:
Let the distance between the two points (x₁, y₁) and (x₂, y₂) is
d = √(x₂ - x₁)² + (y₂ - y₁)²
Here, the given points are (2,8) and (6,8), therefore,
x₁ = 2, x₂ = 6,
y₁ = 8, y₂ = 8
d = √(x₂ - x₁)² + (y₂ - y₁)²
d = √(6 - 2)² + (8 - 8)²
d = √(4)² + (0)²
d = √16
d = 4
Thus, The distance is 4 units.

Todd purchased a jumper for his infant son. The jumper clamps to the top of a door frame and has a spring from
which the body of the jumper hangs to allow the infant to jump up and down. Included with the jumper are small
weights, each identical in
weight and size. The weights allow the user to adjust the initial height of the jumper by
stretching the spring a certain distance. Todd adds 8 of the weights and notes the spring stretches 2 centimeters.
a. According to Hook's Law, the amount that a spring is stretched, s, varies directly with the force applied to the
spring by the weights, F. Write an equation that relates F and s for the spring on the jumper
b. Using your equation from part a, find the stretch in the spring if Todd applies 14 of the included weights to the
spring
c. Using your equation from part
Answers
Hooke's law relates the force applied on an elastic material to its extension. Therefore, the answers to the questions are:
a. F = ks
b. The spring stretched 0.035 m (3.5 cm) when a weight of 14 N is included.
Hooke's law states that provided the extension limit of an elastic material is not exceeded, the force applied is directly proportional to its extension.
i.e F = ke
where F is the force applied to the material, k is the spring constant of the material, and e is the extension.
Considering the conditions in the given question then, we have:
a. The equation that relates F and S for the spring on the jumper is:
F = ks
b. Given that: F = 8 N, while s = 2 cm (0.02 m).
Then;
F = ks
8 = k(0.02)
k = [tex]\frac{8.0}{0.02}[/tex]
= 400
k = 400 N/m
So that, the stretch in the spring when 14 N weight is included is:
F = ks
14 = 400 x s
s = [tex]\frac{14}{400}[/tex]
= 0.035
s = 0.035 m
Thus the spring was stretched by 0.035 m (3.5 cm) when a weight of 14 N was included.

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
We have P(A) = 0.40 and P(B) = 0.5
and, P(A and B) = 0.10
Using Conditional Probability
P(B|A) = P(A ∩ B)/P(A)
Substitute the values of P(A), P(B) and P(A ∩ B),
P(B|A) = 0.10/ 0.40
P(B|A) = 0.25
