Step-by-step explanation:
the inverse function simply calculate the original x it of a given y. so, we need to transform the original function to calculate x instead of y.
and then, at the end to make it a formally correct function definition, we rename x to y and y to x.
y = x + 3
x = y - 3
=> to make it a formally correct function definition
y = x - 3 = h(x)
If a baby weighs 7 lbs at birth and 12 Ibs after 20 weeks, how much did the baby weigh after 4 weeks, assuming linear growth? [?] lbs
Answer: 8lbs
Step-by-step explanation:
The baby gained one pound
Assuming linear growth, the baby would weigh approximately 8 lbs after 4 weeks.
How to determine the weight of the babyAssuming linear growth, we can use the concept of a slope to estimate the baby's weight after 4 weeks.
Given information:
Weight at birth (0 weeks): 7 lbs
Weight after 20 weeks: 12 lbs
We can calculate the rate of change (slope) of the baby's weight per week:
Slope = (Change in weight) / (Change in weeks)
Slope = (12 lbs - 7 lbs) / (20 weeks - 0 weeks)
Slope = 5 lbs / 20 weeks
Slope = 0.25 lbs/week
Now, using the slope, we can estimate the baby's weight after 4 weeks:
Estimated weight change = Slope * Number of weeks
Estimated weight change = 0.25 lbs/week * 4 weeks
Estimated weight change = 1 lb
So, the baby's weight after 4 weeks would be the initial weight (7 lbs) plus the estimated weight change (1 lb):
Estimated weight after 4 weeks = Initial weight + Estimated weight change
Estimated weight after 4 weeks = 7 lbs + 1 lb
Estimated weight after 4 weeks = 8 lbs

please someone answer with an explanation if possible!
Answer:
download gauth math and scan it and will give u the answer
Answer:
C
Step-by-step explanation:
The y intercept is where the line first crosses the y axis, so it would be positive 2. The slope is negative because it's diagonally going the left way, and its 3 because from one point to another it's 3 down and 1. The formula for a slope is rise/run, in this case it would be 3/1 which is 3.

Paul paid $663 for a new freezer. He paid for the freezer with his credit card, which has an interest rate of 15.28% compounded monthly, and made monthly payments for five years until the freezer was paid off. He kept the freezer for seven years, and it used an average of $2.14 of electricity per week. Paul made no other purchases or payments with his credit card until the freezer was paid off. Between the interest and the electricity, which component of the lifetime cost of the freezer was greater, and how much greater was it? (Round all dollar values to the nearest cent.)
a.
The interest cost $106.60 more than the electricity.
b.
The interest cost $173.24 more than the electricity.
c.
The electricity cost $489.76 more than the interest.
d.
The electricity cost $115.96 more than the interest.
Answer:
c
Step-by-step explanation:
The electricity cost $489.76 more than the interest.
Thus, option C is correct.
What is Interest cost?Interest cost is the total measure of interest a borrower pays on an obligation commitment over the existence of the getting. Interest is paid on the obligation notwithstanding reimbursement of head.
The formula will be:
I = A - P
I = 663(1 + 0.1528/12)^(5*12) - 663
I = 663(1 + 0.1528/12)^60- 663
I = 1416.51 - 663
I = $753.51
The bill for electricity for 7 years and 52 weeks per year will be
= 7 x 52 x 2.14
= $778.96
The electricity cost is bigger than the interest:
$778.96 is bigger than $753.51 by $25.45:
$778.96 - $753.51 = $25.45.
Therefore, option C is correct.

After using the linear equations method we will get 1.76.
What is linear equations?
An equation is said to be linear if the highest power of a variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the standard form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present. A linear equation is one that has a degree of 1 as its highest value. No variable in a linear equation, then, has an exponent greater than 1. A linear equation's graph will always be a straight line.

multiplying with 4 to find 4 X 8.
Multiplying by 4 using the doubles strategy utilizes the fact that 4 is double of 2. Hence, 4 time any number is double of 2 times that number. Thus, given 4 x 8, it can be evaluated using the double strategy as follows 2 x 8 + 2 x 8 = 16 + 16 = 32

Step-by-step explanation:
If a fair coin is tossed twice the possible outcomes are HH, HT, TH or TT, where HH means both tosses are heads and HT means that the first toss is a head and the second toss is a tail, etc. Since the coin is fair, a 50-50 chance of getting a head or a tail, we assign a probability of 1/4 to each of the four outcomes. Assuming that a fair coin was tossed twice, find the probability that both tosses were heads given that at least one of the tosses was a head. Round your answer to 4 decimal places.
The conditional probability value rounded to 4 decimal places is : 0.2500
The relation can be used to find the conditional probability of events given :
P(HH | Atleast 1 head) = P(HHn(Atleast 1 H)) / P(Atleast 1 H)
P(Atleast 1 H) = P(HT + TH + HH)
P(Atleast 1 H) = P(HT + TH + HH) = 3(0.25) = 0.75
P(HHn(Atleast 1 H)) = P(HH) × P(Atleast 1 H) = 0.25 × 0.75 = 0.1875
Therefore, the conditional probability can be expressed as :
P(HH | Atleast 1 head) = 0.1875 / 0.75 = 0.25Therefore, P(HH | Atleast 1 head) is 0.25
