If Y = 17 inches, Z = 22 inches, H = 7 inches, and W = 4 inches, what is the area of the object?
A.
352 square inches
B.
242 square inches
C.
175 square inches
D.
165 square inches
Answers
reason is that area of a traingle is base times hight divided by 2 so H times Z divided by two =(22x7)/2==77
then you add the area of the rectangle on the bottom (W times Z )= 88
77+88=165
Hope this makes sense and I get brainiest!!

Tomas can do a job in 4 hours. julia can do the same job in 6 hours. how many hours will it take the two of them to do the job if they work together?
Answers
job/time1 + job / time2 = job / t
job = 1
t = the time for both working together.
t1 = 4 hours
t2 = 6 hours
d = 1 job
1/t1 + 1/t2 = 1/t
1/4 + 1/6 = 1/t
find the lowest common denominator between 6 and 4
4 = 2 * 2
6 = 2 * 3
The lowest common denominator = 2 * 2 * 3 which is 12
3*1 / 4*3 + 2*1 / 2 * 6 = 1/t
3/12 + 2 / 12 = 1/t
5/12 = 1/t Cross multiply
5t = 12 * 1 Divide by 5
t = 12 / 5
t = 2 2/5
t = 2.4 hours.<<<<< answer
Notice that the time is less than 4 hours as it should be.

Which of the following is a solution of x2 + 6x = −18?
Answers
The correct option are a. [tex]\(x = -3 + 3i\)[/tex] and b. [tex]\(x = -3 - 3i\)[/tex].The solutions are complex numbers [tex]\(x = -3 + 3i\)[/tex] and [tex]\(x = -3 - 3i\)[/tex].
To find the solution of the quadratic equation [tex]\(x^2 + 6x = -18\)[/tex], we need to solve it for [tex]x[/tex].
Starting with the given equation:
[tex]\[x^2 + 6x = -18\][/tex]
Rearranging it to the standard form of a quadratic equation:
[tex]\[x^2 + 6x + 18 = 0\][/tex]
Now, to find the solutions, we can use the quadratic formula:
[tex]\[x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}\][/tex]
where [tex]\(a = 1\), \(b = 6\)[/tex], and [tex]\(c = 18\).[/tex]
Substituting the values:
[tex]\[x = \frac{{-6 \pm \sqrt{{6^2 - 4 \cdot 1 \cdot 18}}}}{{2 \cdot 1}}\]\[x = \frac{{-6 \pm \sqrt{{36 - 72}}}}{2}\]\[x = \frac{{-6 \pm \sqrt{{-36}}}}{2}\]\[x = \frac{{-6 \pm 6i}}{{2}}\]\[x = -3 \pm 3i\][/tex]
So, the solutions are complex numbers [tex]\(x = -3 + 3i\)[/tex] and [tex]\(x = -3 - 3i\)[/tex].
The complete question is:
Which of the following is a solution of [tex]\(x^2 + 6x = -18\)[/tex]?
a) [tex]\(x = -3 + 3i\)[/tex]
b) [tex]\(x = -3 - 3i\)[/tex]
c) [tex]\(x = -3\)[/tex]
d) [tex]\(x = 3\)[/tex]
For an investment of $26,245, a quarterly statement reports that the account balance is $26,292. The statement also reports that for the same quarter, the rate of return on the investment was -0.02%. Given the information regarding the investment's current balance, does the reported rate of return seem reasonable? Use complete sentences to explain your answer.
Answers
No, the reported rate of return does not seem reasonable.
Answer:
Rate of return is 0.2% positive according to given data. The given rate of return is inconsistent with the given data.
Step-by-step explanation:
The rate of return on the statement is inconsistent with the information given.
As per given data
Investment = $26,245
Account balance = $26,292
Return on the investment
Difference = $26,292 - $26,245 = $47
Investment is increase by $47
Now calculate the percentage of rate of return.
Percentage change = ($47 / $26,245) x 100 = 0.2%
Rate of return is 0.2% positive according to given data. Hence proved that, the given rate of return is inconsistent.

What is the range of the function y = -x2 + 1?
Answers
Final answer:
The range of the function y = -x^2 + 1 is all real numbers less than or equal to 1, represented as ]-∞, 1].
Explanation:
The range of the function y = -x^2 + 1 refers to the set of all possible values that y can take as x varies over all real numbers. Since the function is a downward-opening parabola (due to the negative coefficient of x^2), the maximum value of y is at the vertex of the parabola. The vertex, in this case, occurs at x=0, which gives us the maximum y value of y = 1. As x moves away from zero in either direction, the value of y decreases and approaches negative infinity. Hence, the range of this function is ]-∞, 1], or all real numbers less than or equal to 1.

Determine the values of x on which the function f(x)=2x^2-x-15/4x^2-12x is discontinuous and verify the type of discontinuity at each point.
A.There is a vertical asymptote at 0 and a hole at 3.
B.There are vertical asymptotes at -5/2 & 0 and a hole at 3.
C.There is a vertical asymptote at 3 and a hole at 0.
D.There are vertical asymptotes at 0 & 3.
Answers
There is a vertical asymptote at x = 0 (because the denominator becomes 0). We need to further analyze the behavior at x = 3 to see if it's a hole (cancellation) or the function is continuous there (Option A or B might be the answer).
Step 1: Identify Potential Discontinuities
A rational function (like f(x)) is discontinuous when its denominator is zero. So, we need to find the values of x that make the denominator 0:
Denominator = 4x^2 - 12x = 0
Factor the denominator: 4x(x - 3) = 0
This gives us two possible values for x: x = 0 and x = 3.
Step 2: Verify Discontinuity Type at Each Point
Check if the function is defined (has a value) at these points.
x = 0: If we plug x = 0 in the original function, we get 0/0, which is indeterminate. This suggests a potential vertical asymptote at x = 0.
x = 3: If we plug x = 3 in the original function, the expression doesn't become 0/0. The function might have a hole or be continuous at x = 3.
Step 3: Analyze for Holes (Optional):
To further investigate x = 3, we can try to simplify the function by factoring the numerator (possible because the denominator is already factored). If the simplification gets rid of the term that causes the 0/0 at x = 3, it creates a hole.

There are 750 toothpicks in a regular sized box. If a jumbo box is made by doubling all the dimensions of the regular sized box, how many toothpicks will the jumbo box hold? (With work pls)
Answers
To answer this, let the 3 sides of the regular sized rectangular box be x, y, and z.
When we double all the sides, the new sides have lengths 2x, 2y, and 2z, respectively.
Since the regular box (with dimensions x,y, and z) have 750 toothpicks, we can write
[tex]xyz=750[/tex]
Similarly we can write for the jumbo box as,
[tex](2x)(2y)(2z)[/tex]
which is equal to [tex]8(xyz)[/tex]
So this is 8 times the original of [tex]xyz[/tex]. Hence the jumbo box will have 8 times 750 number of toothpicks.

1) If the endpoints of the diameter of a circle are (9, 4) and (5, 2), what is the standard form equation of the circle?
Answers
Midpoint = [tex]( \frac{X1+X2}{2} , \frac{Y1+Y2}{2} )[/tex]
where X1 is the x-coordinate of the first ordered pair and Y1 is the y-coordinate of the first ordered pair. Same applies to X2 and Y2. So now we plug in.
Mdpt = [tex]( \frac{9+5}{2} , \frac{4+2}{2} )[/tex]
= [tex]( \frac{14}{2} , \frac{6}{2} )[/tex]
Your midpoint is at (7, 3).
This gives you the beginning of the equation. The equation of a circle is:
(x - h)² + (y - k)² = radius²
where (h, k) is the center.
Your equation is:
(x - 7)² + (y - 3)² = radius²
To find the radius, we do either the distance formula from the center to either of the endpoints. Or the distance between the two endpoints divided by two. Depends on which one you want to do. I choose the latter, but it's all personal preference.
Distance formula = √((X2 - X1)² + (Y2 - Y1)²)
So we plug in:
D = √((5 - 9)² + (2 - 4)²)
D = √((- 4)² + (- 2)²)
D = √(16 + 4)
D = √20
Distance of the diameter = 2√5
Now divide that by 2, your radius is √5
Now we plug in to the equation:
(x - 7)² + (y - 3)² = (√5)²
Your final equation is:
(x - 7)² + (y - 3)² = 5
