Answer:
y = $38.97
y = 6.495(5) + 6.495
Step-by-step explanation:
So for this problem, since it states the cost and length of the subscription are related, you can use the two subscription costs as data (or coordinate) points.
1 year = 12.99, 3 year = 25.98; so (1,12.99), (3, 25.98) use these points to calculate the average rate of change (or the slope (m)).
(y - y1)/(x - x1) = m so, (25.98-12.99)/(3 - 1) = 6.495, this is the slope, m
y = 6.495(x) + b now just pick one of the points and put in the x and y values to solve for b
12.99 = 6.495(1) + b solve for b and you discover it also = 6.495 = b
so y = 6.495(x) + 6.495 is the equation of the line, to answer their question, just pop in x=5 for the 5 years subscription cost
y = 6.495(5) + 6.495
y = $38.97
Evaluate the function rule for the given value.
y = 8 ∙ 3x for x = 4
1944
647
96
648
Answer:
96
Step-by-step explanation:
y=8.3x
x=4
Substituting x as 4,
y=8*3*4
y=8*12
y=96
Hence, x=4, y=96
Charlotte has $900 in a savings account that earns 8% annually. The interest is not
compounded. How much interest will she earn in 1 year?
Use the formula /= prt, where / is the Interest earned, p Is the principal (starting amount), r
Is the Interest rate expressed as a decimal, and t is the time in years.
P=900 - the principal
R=0.08 - 8% as a decimal, the rate
T=1 - one year.
I=PRT
I=900(0.08)(1)
I=900(0.08)
I=72
Charlotte will earn $72 in one year.
The biologist is expecting the number of salmon to rise during salmon season. If the ratio stays the same and he expects 120 Steelhead, how many Chinook should he expect to count at the dam? Show your work.
Based on the ratio of Chinooks to Steelhead, if there are 120 Steelheads, the biologist should expect to count 48 Chinooks.
How many Chinooks will the Biologist find?The first part of the question shows that for every 4 Chinooks, there are 10 Steelheads.
The ratio of Chinooks to Salmon is therefore:
= 10 / 4
= 2.5
This means that for every 1 Chinook, there are 2.5 Steelhead.
If there are 120 Steelheads, the number of Chinooks would be:
= 120 / 2.5
= 48 Chinooks

write a linear equation in slope-intercept form. slope=1/2 and y-intercept= -6
Answer:
y=1/2x-6
Step-by-step explanation:
Slope intercept form is y=mx+b so plug it into the equation and it is y=1/2x-6.
y=1/2-6
Solution:Since we're given the line's slope and y-intercept, we can easily determine its equation.Remember, slope-intercept looks like so: y=mx+bIn this formula, the letter "m" stands for the slope, and "b" stands for the y-intercept.Therefore, the line's equation is:y=1/2-6Hope it helps.

The population of a certain inner-city area is estimated to be declining according to the model P(t)=259,000e−0.012t, where t is the number of years from the present. What does this model predict the population will be in 13 years? Round to the nearest person.
Answer:
259000 people
Step-by-step explanation:
Since t is the number of years, you sub 13 into the equation as t,
P(13)=259,000e−0.012(13)
= 258999.844 (round since its people --> 259000)

The time it take the ball to reach 156feet above the ground level is 0.5 secs and 5.5 seconds
Functions and valuesGiven the height of the ball expressed by the function below;
h = -16t^2 + 96t + 112
where
t is the time in seconds
If the car is 156ft above the ground, hence
Substitute
-16t^2 + 96t + 112 = 156
Multiply through by -1
16t^2 - 96t - 112 = -156
16t^2 - 96t - 112 + 156 = 0
16t^2 - 96t + 44 = 0
4t^2 - 24t + 11 = 0
Factorize
On factorizing, the positive value of "t" is 0.5 secs and 5.5 seconds
Hence the time it take the ball to reach 156feet above the ground level is 0.5 secs and 5.5 seconds

How can you use dilations to solve real world problems?
You can use dilations when drawing blueprints to.......
scale, move or rotate? Which one is it?
Dilation is used in eye exams so that the eye doctor can view the patient's eye better. After a while it will slowly reduce in size and return back to normal.
A microscope dilates a specific specimen four times larger. A microscope, a projector, a model boat, or a model of a city. All of these use dilation..

in a company 37% of the 1500 employees are females
work out the number of males in the company
I'm struggling pls help me
Answer:
Answers : 945 males
Step-by-step explanation:
37%
555 females
1500 - 555
total males = 945
Answer:
945 males
Step-by-step explanation:
37% of 1500 = female
37% of 1500 = 555 (number of females)
1500 - 555 = number of males
1500-555 = 945
To double check this, we can do:
100% - 37% = 63% of 1500 are males
63% of 1500 = 945
So, the answer is 945
I can assure you this is the correct answer.
