Step-by-step explanation:
A birdbath is filled to the top. On Day 1, the volume of water in the bowl decreases by 7/8 cup. On Day 2, the volume in the bowl decreases by 3/4 cup. What number represents the total change in the volume of water in the bowl after two days? Write your answer as a mixed number.
Answer:
-1 5/8
Step-by-step explanation:
Let the total amount in the bowl be x;
If on Day 1, the volume of water in the bowl decreases by 7/8 cup, the remaining water will be;
x - 7/8
If on day 2, the volume in the bowl decreases by 3/4 cup, the remaining volume of water after the second day will be;
= x - 7/8 - 3/4
= x - (7-2(3))/8
= x - (7+6)/8
= x - 13/8
This shows that the total change after the two days is -13/8
As a mixed fraction;
-13/8 = -1 5/8

Use the distributive property to remove the parentheses (x+12)8
Answer:
Using distributive property to remove the parentheses [tex](x+12)8[/tex] we get [tex]8x+96[/tex]
Step-by-step explanation:
We need to use distributive property to remove the parentheses (x+12)8
According to distributive property of multiplication over addition:
[tex]a(b+c)=ab+ac[/tex]
Now, using the above distributive property to solve the given question. Multiply 8 with terms inside the bracket and solving:
[tex](x+12)8\\=8x+8*12\\=8x+96[/tex]
So, using distributive property to remove the parentheses [tex](x+12)8[/tex] we get [tex]8x+96[/tex]
Consider the composite function g(F(x)) = x square root of 6.
If f(x) = 3x2, what is g(x)?
Answer:
g(x) = √(2x)
Step-by-step explanation:
f(x) = 3x^2
g(f(x)) =√6x
g(3x^2) = x√6
g(x) must be √(2x)
because if we substitute x = 3x^2 in this we get
(√2(3x^2))
= √2√3√(x^2)
= √6 x

Can a quadratic have one real and one non real root
Answer:
Yes, it is possible. We already know that complex roots exist in conjugate pair but the case is true only when the equation has real coefficients. But on the other hand, if the equation has complex coefficients, then it is possible to attain one real and one complex root.

Seema deposited $800 in a saving account earning 2.88% compounded annually. To the nearest cent, how much will she have in 16 years? Do not include the dollar sign in your answer.
Answer:
1260.04
Step-by-step explanation:
The formula for compound interest is:
A = P(1+[tex]\frac{r}{n}[/tex][tex])^{nt}[/tex] where A is the final amount, P is the initial principal balance, r is the interest rate, n is the number of times interest applied per time period and t is the number of time periods elapsed. Since the deposit was compounded annually, just like the interest, we can omit the n in the equation.
Applying the formula to question:
800(1+[tex]\frac{2.88}{100}[/tex][tex])^{16}[/tex] = 1260.04 (rounded off to nearest cent since it's money)
In rectangle ABCD, point E lies half way between sides AB and CD and halfway between sides AD and BC. If AB=3 and BC=2, what is the area of the shaded region? Write your answer as a decimal, if necessary. Do not include units in your answer.
Answer:
The area of the shaded region is 3.
Step-by-step explanation:
Since point E lies halfway between AB and BC, the area of the shaded region (As) consists of two identical triangles with base equal to AB and height equal to half the measure of BC:
[tex]A_s=2 * A_t[/tex]
Where At is the area of each triangle.
[tex]\displaystyle A_t=\frac{AB*BC/2}{2}[/tex]
[tex]\displaystyle A_t=\frac{AB*BC}{4}[/tex]
We know AB=3 and BC=2, thus:
[tex]\displaystyle A_t=\frac{3*2}{4}=\frac{6}{4}[/tex]
Simplifying:
[tex]\displaystyle A_t=\frac{3}{2}[/tex]
Finally:
[tex]\displaystyle A_s=2 * \frac{3}{2}[/tex]
[tex]A_s=3[/tex]
The area of the shaded region is 3.
Note the area of the shaded region is half the area of the rectangle.

Answer:
x = 120
Step-by-step explanation:
Let's draw an imaginary dot in the middle of that line which runs between those two parallel lines, and now lets look at it as an angle.
This lines' angle is 180 degrees. Now lets move those two parallel lines together on the imaginary dot in the middle.
We can see that on the left side is one degree and the other side is another, however when we put them together we get the angle measurement of the our line which we identified was 180.
Now that we can see that our two angles must equal 180 when put together we know and can say that:
40 + (x + 20) = 180
So, lets work this out like basic algebra now.
40 + x + 20 = 180
x + 60 = 180
- 60 - 60
x = 120
And voila we have our x value.
Hope this helps :)

Which point is on the graph of f(x)=|x-6|+7?
(5,8)
(8,10)
(6,9)
(3,11)
(4,12)
Answer:
(5, 8)
Step-by-step explanation:
Convert the f(x) = to a y =
f(x) = | x - 6 | + 7
y = | x - 6 | + 7
Plug in the values and prove
y = | x - 6 | + 7
(5,8)
8 = | 5 - 6 | + 7
8 = | -1 | + 7
8 = 1 + 7
8 = 8; true
(8,10)
10 = | 8 - 6 | + 7
10 = | 2 | + 7
10 = 2 + 7
10 = 9; false
(6, 9)
9 = | 6 - 6 | + 7
9 = | 0 | + 7
9 = 0 + 7
9 = 7; false
(3, 11)
11 = | 3 - 6 | + 7
11 = | -3 | + 7
11 = 3 + 7
11 = 10; false
(4, 12)
12 = | 4 - 6 | + 7
12 = | -2 | + 7
12 = 2 + 7
12 = 9; false
Therefore the only one which falls on the graph is (5, 8)
Hope this helps :)

A cell phone factory has a cost of production C(x) = 150x + 30,000 and a revenue function R(x) = 400x. What is the break-even point?
Given:
Cost function, C(x) and revenue function, R(x) are
[tex]C(x)=150x+30000[/tex]
[tex]R(x)=400x[/tex]
To find:
The break-even point.
Solution:
We know that, at break-even point the cost is equal to revenue.
Equate cost function and revenue function to get the break-even point.
[tex]C(x)=R(x)[/tex]
[tex]150x+30000=400x[/tex]
[tex]30000=400x-150x[/tex]
[tex]30000=250x[/tex]
Divide both sides by 250.
[tex]\dfrac{30000}{250}=x[/tex]
[tex]120=x[/tex]
Put x=120 in R(x).
[tex]R(120)=400(120)[/tex]
[tex]R(120)=48000[/tex]
It means, the revenue and cost are equal, i.e., 48000 at x=120.
Therefore, the break even point is x=120.
120 units of products are required to break even.
Revenue is the amount of money that can be made from selling a particular number of items while cost is the amount of money used to produce those items.
At breakeven point, revenue and cost are the same,
Let x represent the number of units produced. hence at break even:
Revenue = cost
R(x) = C(x)
400x = 150x + 30000
250x = 30000
x = 120 units
Therefore 120 units of products are required to break even.

Darryl said that -32 and (-3)2 have the same value? Do you agree with Darryl? Yes or no? Explain your response.
Answer:
Step-by-step explanation:
Yes
Answer:
Step-by-step explanation:
No, I don't agree with Daryl. If you multiply -3 by 2, you will get -6. -6 is not equal to -32, which means that they don't have the same value, so Daryl is wrong.
