The range of the function y=|x-1|+7 is all real numbers greater than or equal to 7, as the absolute value ensures non-negative values to which 7 is added.
The range of the function y=|x-1|+7 can be determined by analyzing the nature of the absolute value function and the constant term. The absolute value function, |x-1|, ensures that the output is always non-negative for any value of x, since it represents the distance from 1 on the number line, which cannot be negative. Therefore, when we add 7 to this non-negative value, the smallest value y can take is when |x-1|=0, which is when x=1. So, at x=1, y will be 7 since we have 0+7. For any other value of x, |x-1| will be positive, and when adding 7, y will be greater than 7. Hence, the range of y is all values greater than or equal to 7.

Find the measure of angle BCD in the following parallelogram. what's does BCD equal
Answers
Answer:
120 degrees
Step-by-step explanation:
This is a quadrilateral, and by definition, the sum of all the interior angles is 360. So, we can just sum up all the expressions and set them equal to 360:
2x + x + 2x + x = 360
Combine like terms and solve for x:
6x = 360
x = 360/6 = 60
<BCD = 2x = 2 * 60 = 120
Thus, the answer is 120 degrees.

Answers
Answer:
84.82 or 27pi
Step-by-step explanation:
Area of a circle is A=pir^2
so the area of the whole circle would be 6^2pi
so area is 36pi but only 3/4 is shaded so
36pi*3/4=27pi
27*pi≈84.82
Answer:
84.78cm²
Step-by-step explanation:
Angle at the centre:
360 - 90 = 270
Area:
(270/360) × pi × r²
(3/4) × pi × 6²
27pi cm²

Ethan and Evan are twins. They each deposit $3,000 into separate bank
accounts. Ethan's account accrues interest at a rate of 8% annually. Evan's
account compounds interest at a rate of 8% annually. Which of these
accounts can be modeled by linear &/or exponential. Explain why?
Answers
Evan's account can be modeled by exponential growth because it compounds interest. Ethan's account can be modeled by linear growth because it accrues a fixed interest rate annually.
Explanation:The account that can be modeled by exponential growth is Evan's account because it compounds interest. Compound interest involves the exponential growth formula: A = P(1 + r/n)^(nt), where A is the final account balance, P is the principal (initial deposit), r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. In this case, Evan's account compounds interest annually, so n=1.
Ethan's account, on the other hand, can be modeled by linear growth. Linear growth is represented by a straight line on a graph, and it involves a constant rate of increase over time. Ethan's account accrues interest at a fixed 8% annually, so the amount in the account increases by the same amount every year.

[tex]a_n[/tex] = nth term
[tex]a_1[/tex] = first term
[tex]n[/tex] = position of the term
[tex]d[/tex] = common difference
First, lets find the common difference of the sequence.

The function y = 10 x + 190 represents the relationship of the given data where x represents fat, in grams, and y represents calories.
How many calories would there be in a snack with 35 grams of fat?
Answers
Answer:
540 calories
Step-by-step explanation:
We are trying to find y (calories), when x (fat) equals 35 grams.
So, we can substitute 35 in for x
y= 10x +190
y=10(35)+190
Multiply 10 and 35
y=350+190
Add 350 and 190
y=540
A snack with 35 grams of fat will have 540 calories

Answers
Answer:
10%= 40$ 30%=120$
Step-by-step explanation:
ok so u earn 400$ at a yard sale. you divide it by 100 400/100=4. ok so then you multiply four by 10=40 and that is 10% multiply it by 30 u get 120 or 30%
sorry for the bad spelling
To find out how much to donate, you need to understand what percentage means. 10% of $400 is $40 and since 30% is 3 times as much, you should donate $120.
Explanation:To solve this problem, you first need to understand what 10% of a quantity means. 10% of a quantity is simply that quantity divided by 10. If you want to donate 30% of the $400 earned at your yard sale to charity, you first need to find 10% of $400, which is $400 divided by 10. This gives you $40.
Since 30% is the same as three times 10%, you just need to multiply your answer for 10% by 3. Therefore, you should donate $40 times 3, which equals $120.

If people blink about 13 times per minute, how many times do they blink in 7 hours?
Answers
Answer:
Step-by-step explanation:
1 hour=60 min
7 hours=60×7=420 min
number of blink=420×13=5460
Final answer:
To calculate the number of times a person will blink in 7 hours at a rate of 13 blinks per minute, you multiply 13 by the total number of minutes in 7 hours (420) to get 5,460 blinks.
Explanation:
If people blink about 13 times per minute, we can calculate how many times they blink in 7 hours by multiplying the number of blinks per minute by the number of minutes in 7 hours. First, let's find out how many minutes are in 7 hours:
7 hours x 60 minutes per hour = 420 minutes
Now, we'll multiply the number of minutes by the number of blinks per minute:
420 minutes x 13 blinks per minute = 5,460 blinks
Therefore, a person will blink 5,460 times in 7 hours. This is a simple arithmetic multiplication problem that provides us with the total number of blinks over a given period.

What is the value of p?
(Geometry Question)
Answers
Answer:
p = 92
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angle
p+45 = (p-47)+p
Combine like terms
p+45 = 2p-47
Subtract p from each side
p-p+45 = 2p-p-47
45 = p-47
Add 47 to each side
45+47 = p-47+47
92 = p
