it's in slope intercept form so the slope is the number before x
Which list shows these lengths in order from greatest to least?
9514 1404 393
Answer:
√3/11, π/24, 3/25, 9/100
Step-by-step explanation:
The 2-decimal value of each of the numbers is ...
9/100 = 0.09
π/24 = 0.13
3/25 = 0.12
√3/11 = 0.16
Then the order from greatest to least is 0.16, 0.13, 0.12, 0.09. In the original form, that is ...
√3/11, π/24, 3/25, 9/100 . . . . . matches choice B
A phone costs $50 and goes on sale for 20% off. Select the amount that was discounted as well as the final price after the sale
Answer:
Discounted amount = $10
Sales price = $40
Step-by-step explanation:
Given:
Phone cost = $50
Discount rate = 20%
Find:
Discounted amount and sales price
Computation:
Discounted amount = Phone cost x Discount rate
Discounted amount = 50 x 20%
Discounted amount = $10
Sales price = Phone cost - Discounted amount
Sales price = $50 - $10
Sales price = $40
Write an equation in slope-intercept form of the line that passes through (7, 2) and (2, 12).
y =
Answer:
y = - 2x + 16
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (7, 2) and (x₂, y₂ ) = (2, 12)
m = [tex]\frac{12-2}{2-7}[/tex] = [tex]\frac{10}{-5}[/tex] = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 12 )
12 = - 4 + c ⇒ c = 12 + 4 = 16
y = - 2x + 16 ← equation of line

A study of black bears in the Adirondacks reveals that their population can be represented by the function , where is the number of years since the study began. Write a function that models the monthly growth rate (to the nearest hundredth of a percent) of the black bear population
Answer:
[tex]\mathbf{ P(t) = 3500 (1.}00206)^{12t}[/tex]
Step-by-step explanation:
The missing value of the given function is:
[tex]P(t) = 3500 (1.025)^t[/tex]
where
t = no. of years since study began
∴
[tex]P(t) = 3500 (1+0.025)^t[/tex]
Per year, the function can be written as:
[tex]P(t) = 3500 (1+\dfrac{25}{1000})^t[/tex]
For monthly growth rate m = 12
[tex]P(t) = 3500 (1+\dfrac{25}{1000(m)})^{mt}[/tex]
[tex]P(t) = 3500 (1+\dfrac{25}{1000(12)})^{12t}[/tex]
[tex]P(t) = 3500 (1+\dfrac{25}{12000})^{12t}[/tex]
[tex]P(t) = 3500 (1+0.00206)^{12t}[/tex]
[tex]\mathbf{ P(t) = 3500 (1.}00206)^{12t}[/tex]

A sequence is recursively defined as a(n)=2a(n-2) for values of n>2. Find the seventh term of the sequence if a(1)=0 and a(2)=1
Answer:
a(7) = 0
Step-by-step explanation:
Using the recursive formula and a(1) = 0, a(2) = 1 , then
a(3) = 2a(1) = 2(0) = 0
a(4) = 2a(2) = 2(1) = 2
a(5) = 2a(3) = 2(0) = 0
a(6) = 2a(4) = 2(2) = 4
a(7) = 2a(5) = 2(0) = 0

How do you multuply and divide rational numbers! -aspen
Answer:
If you can simplify your problem before you multiply, your problem will be easier to solve. To divide rational numbers, you turn the division problem into a multiplication problem by flipping the second rational number. Then you go ahead and multiply the tops and bottoms together to get your answer.

A store sells paint sets. Each paint set costs the same amount. During the sale, the store reduces the price of each paint set by $1:35. Yuri spends $6:88 on 2 paint sets at the sale price. What was the price of on set before the sale?
Answer: $ 4.79
Step-by-step explanation:
Given: Yuri spends $6.88 on 2 paint sets at the sale price.
Market price of each paint set = [tex]\$\dfrac{6.88}{2} =\$ 3.44[/tex]
During the sale, the store reduces the price of each paint set by $1.35.
Price of paint set before sale = Market price + $1.35
= $ ( 3.44 + 1.35)
= $ 4.79
Hence, the price of on set before the sale = $ 4.79
Which of the following expressions is equivalent to the logarithmic

C. lo94 7 + 3 log4 X
D. 3 log4 7 + log4 X
Answer:
O B. log4 7-3 log4 x
[tex] log_{4}( \frac{7}{ {x}^{3} } ) \\ = log_{4}7 - log_{4}{x}^{3} \\ = log_{4}7 - 3 log_{4}x[/tex]
The expression equivalent to the logarithmic expression

What is log ?
A logarithm is the power to which a number must be raised in order to get some other number
log 4 ([tex]\frac{7}{x^3}[/tex])
log 4.7 - log 4x^3 (log (a/b) = log a - log b

Step-by-step explanation:
What is the value for x?
Answer:
All angles must add up to 180, so if you add 69+5x+2+9y-3, it is = to 180.
First we can subtract 68 cancelling out 69, 2 and -3 so it is
5x+9y = 112. I assume this is an iscoceles triangle so we already knew 9y - 3 = 69, y=8, x=8

a salesperson earns 9 commission on sales.the equation for the amount he or she earns in commission is c = 0.9s, where s is the amount sold . How much commission will he or she earn if the amount sold is $6,000?what is the ordered pair
Answer:
c = $5,400
Step-by-step explanation:
Given:
c = 0.9s
where,
s = amount sold
c = commission on sales
How much commission will he or she earn if the amount sold is $6,000?
Find c when she = $6,000
c = 0.9s
= 0.9 × 6,000
= 5,400
c = $5,400
(c, s) (5400, 6000)
