The base of a parallelogram is 24 inches longer than three times the height. The area of the parallelogram is 384 square inches. What is the height?
The height is x = ________ inches.
To find the height of the parallelogram, set up the equation (3x + 24) x = 384 using the formula for the area of a parallelogram. Solve the resulting quadratic equation to find that x, representing the height, is 8 inche
The student is trying to find the height of a parallelogram when the base is 24 inches longer than three times the height and the area is 384 square inches. Let the height of the parallelogram be represented by x inches. According to the problem, the base (b) is 3x + 24 inches. Using the formula Base x Height = Area of parallelogram, we can set up the equation:
(3x + 24) x= 384
Now solve for x using the distributive property:
3x^2 + 24x = 384
Next, set the equation to zero:
3x^2 + 24x - 384 = 0
Divide the entire equation by 3 to simplify:
x^2 + 8x - 128 = 0
Factor the quadratic equation:
(x + 16)(x - 8) = 0
Set each factor equal to zero:
x + 16 = 0 or x - 8 = 0
Since the height cannot be negative, x = 8 is the solution. Therefore, the height of the parallelogram is 8 inches.
Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = 4x2 + 24x + 30?
The graph of f(x) = x2 is widened.
The graph of f(x) = x2 is shifted left 3 units.
The graph of f(x) = x2 is shifted up 30 units.

Which ordered pair will be the solution for the function y = 12 - x?
(7, 4)
(6, 6)
(4, 9)
(2, 14)
The solution to the function y = 12 - x is the ordered pair (6, 6) because when we substitute x = 6 into the function, the result, y, is also 6, which matches the given y-value in the pair.
Explanation:To find the ordered pair that is a solution for the function y = 12 - x, we need to substitute the x-values of each given ordered pair into the equation and see which one gives a resulting y-value that matches the one in the pair.
(7, 4): y = 12 - 7 = 5 – This does not match the y-value of 4.(6, 6): y = 12 - 6 = 6 – This is correct, as it matches the y-value of 6.(4, 9): y = 12 - 4 = 8 – This does not match the y-value of 9.(2, 14): y = 12 - 2 = 10 – This does not match the y-value of 14.Therefore, the solution to the function is the ordered pair (6, 6).

1. Astronomers measure large distances in light-years. One light year is the distance that light can travel in one year, or approximately 5.88 x 10^12 miles. Suppose a star is 9.8 x 10^1 light years from Earth. In scientific notation, approximately how many miles is it?
A. 5.88 x 10^13 miles
B. 5.76 x 10^14 miles
C. 5.88 x 10^12 miles
D. 9.8 x 10^12 miles
2. A 1,600.00 principal earns 7% annual interest, compounded semiannually (twice per year). After 33 years, what is the balance in the account?
A. $4,979.11
B. $14,920.54
C. $112,992.00
D. $15,494.70
Answer:
1. B. 5.76 × 10¹⁴ miles.
2. D. $15,494.70
Step-by-step explanation:
Question 1: We have,
Distance light traveled in one year = 5.88 × 10¹² miles.
Since, the star is 9.8 × 10¹ light years away.
So, we get,
Total number of miles the star is away = 5.88 × 10¹² × 9.8 × 10¹ = 57.62 × 10¹³ miles.
Hence, the total number of miles are 5.76 × 10¹⁴ miles.
Question 2: We have,
Principle amount, P= $1,600
Rate of interest, r = 7% = 0.07
Time period, t = 33 years
Moreover, the interest is compounded twice per year i.e. n=2.
Since, Amount = [tex]P(1+\frac{r}{n})^{nt}[/tex]
i.e. Amount = [tex]1600(1+\frac{0.07}{2})^{2\times 33}[/tex]
i.e. Amount = [tex]1600(1+\frac{0.035)^{66}[/tex]
i.e. Amount = [tex]1600(1.035)^{66}[/tex]
i.e. Amount = [tex]1600\times 9.68418}[/tex]
i.e. Amount = $15,494.70
Hence, the balance in the account is $15,494.70.
The sum of the first 30 terms of the sequence an=6n+5 is
Answer:
[tex]S_{30}=2940[/tex].
Step-by-step explanation:
Given : [tex]a_{n} =6n+5[/tex].
To find : The sum of the first 30 terms .
Solution: We have given [tex]a_{n} =6n+5[/tex].
For n = 1
[tex]a_{1} =6(1)+5[/tex].
[tex]a_{1} =6+5[/tex].
[tex]a_{1} =11[/tex].
For n =2
[tex]a_{2} =6(2)+5[/tex].
[tex]a_{2} =17[/tex].
Common difference = 17 - 11 = 6.
Sum of nth term : [tex]S_{n} =\frac{n}{2}[2a+(n-1)d][/tex].
d = common difference = 6.
For n = 30 .
[tex]S_{30} =\frac{30}{2}[2(11+(30-1)6][/tex].
[tex]S_{30} =15[22+29 *6][/tex].
[tex]S_{30} =15[22+29 *6][/tex].
[tex]S_{30} =15[22+174][/tex].
[tex]S_{30} =15[196][/tex].
[tex]S_{30}=2940[/tex].
Therefore, [tex]S_{30}=2940[/tex].
The solution set for 7q2 − 28 = 0 is { }. (Separate the solutions with a comma) NextReset
Answer:
{ 2,-2}
Step-by-step explanation:
In order to solve this set we just have to first clear the "q":
[tex]7q^{2} -28=0\\7q^{2} -28+28=+28\\7q^{2} =28\\\frac{7q^{2}}{7} =\frac{28}{7} \\q^{2}=4\\\sqrt{q^{2}} =\sqrt{4} \\q= 2, -2[/tex]
So as we know the solution for a square root is always a negative and positive number, so the solutions ser for 7q2-28=0 is 2 and -2
Function f, shown below, is translated down 3 units and left 4 units to create function g. f(x)=3|x-2|-5. Fill in the values of a, h, and k to write function g.
Answer:
g (x) = 3lx+2l-8
Step-by-step explanation:
Carlosego made a mistake on the horizontal shift.
y = f (x + c) shifts the graph c units to the left.
Therefore, g (x) = 3lx - 2 + 4l - 8 is
g (x) = 3lx+2l-8

A company has found that the demand for its product varies inversely as the price of the product. when the price x is 3.5 dollars, the demand yy is 450 units. find a mathematical model that gives the demand y in terms of the price x in dollars.
The mathematical model that gives the demand, y, in terms of the price, x, is y = 1575/x.
Explanation:To find a mathematical model that gives the demand, y, in terms of the price, x, we can use the formula for inverse variation. Inverse variation is described by the equation y = k/x, where k is a constant. To find the value of k, we can use the given information: when x = 3.5, y = 450. Substituting these values into the equation, we get 450 = k/3.5. Solving for k, we find that k = 1575. Therefore, the mathematical model that gives the demand, y, in terms of the price, x, is y = 1575/x.

Jerry goes to the bank and borrows $9,000 for farm equipment. The simple yearly interest is 9.5% and he pays off the loan over a period of 2 years with 24 equal monthly payments. What’s Jerry’s monthly payment
Jerry's monthly payment can be calculated using the formula for the monthly payment on a loan. Plugging in the given values will give the exact monthly payment amount.
Explanation:To calculate Jerry's monthly payment, we can use the formula for the monthly payment on a loan:
Monthly Payment = P × r × (1 + r)^(n) / ((1 + r)^(n) - 1)
Where:
P is the principal amount borrowed, which is $9,000r is the monthly interest rate, which is calculated by dividing the annual interest rate by 12 and converting it to a decimal. In this case, it would be 9.5% / 12 = 0.0079 (rounded to four decimal places)n is the total number of payments, which is 2 years × 12 months = 24 monthsPlugging in the values:
Monthly Payment = $9,000 × 0.0079 × (1 + 0.0079)^(24) / ((1 + 0.0079)^(24) - 1)
Simplifying this equation will give us the monthly payment amount.
find the measure of side c.
The length of side AB (c) in triangle ABC is 31.38 m.
In triangle ABC, angle BCA is a right angle with a measure of 90 degrees, and angle CAB has a measure of 42 degrees.
The side BC has a length of 21 m and the side AB has a length of c.
To find the length of side c, we can use the trigonometric function sine.
By using the sine function and the given angle CAB, we can calculate the length of side c as follows:
c = AB = BC * sin(CAB) = 21 * sin(42) = 31.38 m
Therefore, The length of side AB (c) in triangle ABC is 31.38 m.
The probable question may be:
In triangle ABC, Angle BCA= 90 degree, angle CAB=42 degree, Side BC (a)=21 m, Side AB=c, find the measure of side c.

How many real number solutions exist for 2x2 + 8x + 8 = 0?
Final answer:
There are no real number solutions for the given equation.
Explanation:
The given equation is 2x² + 8x + 8 = 0. To find the number of real number solutions for this equation, we can use the discriminant of the quadratic equation. The discriminant is given by the formula D = b² - 4ac, where a, b, and c are the coefficients of the quadratic equation.
In this case, a = 2, b = 8, and c = 8. Substituting these values into the formula, we get D = 8² - 4(2)(8) = 16 - 64 = -48.
Since the discriminant is negative (-48), there are no real number solutions for the equation. Therefore, the answer is 0.
