What is the line of symmetry for the parabola whose equation is y = x2 + 10x + 25?
A-x = -5
B-x = 5
C-x = -10
Answers
Answer:
x = -5
Step-by-step explanation:
Please write this as y = x^2 + 10x + 25. Here the coefficients are {1, 10, 25}.
The equation of the axis of symmetry is x = -b/[2a], which here is
x = -10 / [2*1] = -5
Solve d/4+7/8=6
What is d?
Answers
Answer:
the answer is d=20.5 hope this helped
Answer:
d= 20.5
Step-by-step explanation:
d/4+7/8=6
(we know that to add fractions, we have to have both denomiators the same number. We aslo know that that means 8. Using that information, we know that to top number must be 48. 48/8 = 6. We can substract)
48-7= 41
(we then need to divide by 2 as we would have had to already multiplyed 4 by 2.)
41/2 = 20.5

Which expression represents the area of the shaded region?
Answers
Given:
A circle of radius r inscribed in a square.
To find:
The expression for the area of the shaded region.
Solution:
Area of a circle is:
[tex]A_1=\pi r^2[/tex]
Where, r is the radius of the circle.
Area of a square is:
[tex]Area=a^2[/tex]
Where, a is the side of the square.
A circle of radius r inscribed in a square. So, diameter of the circle is equal to the side of the square.
[tex]a=2a[/tex]
So, the area of the square is:
[tex]A_2=(2r)^2[/tex]
[tex]A_2=4r^2[/tex]
Now, the area of the shaded region is the difference between the area of the square and the area of the circle.
[tex]A=A_2-A_1[/tex]
[tex]A=4r^2-\pi r^2[/tex]
[tex]A=4r^2-\pi r^2[/tex]
[tex]A=r^2(4-\pi )[/tex]
Therefore, the correct option is (a).

A certain bacterium has an exponential growth rate of 25% per day. If we start with 0.5 gram and provide unlimited resources, how many bacteria can we grow in 2 weeks? Round to the nearest tenth of a gram. HINT: How many days are in a week?
Answers
Answer:
FV= 11.369 gr
Step-by-step explanation:
Giving the following information:
Growth rate (g)= 25% per day
Number of periods (n)= 14 days
Present Value (PV)= 0.5 gr
To calculate the Future Value(FV) in grams, we need to use the following formula:
FV= PV*(1+i)^n
FV= 0.5*(1.25^14)
FV= 11.369 gr
Brittney sewed together fabric triangles to make the quilt square shown below.
How much fabric did Brittney use for each white triangle?
Answers
Answer:
6 in. per triangle & 24 in total (white squares only)
Step-by-step explanation:
So, one side is 12 inches and each side is made up of one blue and one white. With this you can just divide each side by 2, getting 6. There are 4 sides so,
4 sides X 6 in. per each square= 24
Therefore, she used 24 in. in total and 6 for each triangle.

In the diagram of EHG below, JF || HG, EJ=3, JH=18, and FG=72. What is the length of EG
Answers
Answer:
EG = 84
Step-by-step explanation:
Here, we want to get the length of EG
Mathematically, we will be considering two triangles
these are EFJ and EHG
These two triangles are similar as can be seen
when two triangles are similar, the ratio of their corresponding sides are equal
Thus, we have it that;
EH/EG = EJ/EF
let us represent EF by x
so; EG is (x + 72)
EH = 3 + 18 = 21
Hence, we have it that;
21/x+ 72 = 3/x
21(x) = 3(x + 72)
21x = 3x + 216
21x-3x = 216
18x = 216
x = 216/18
x = 12
EG = 12 + 72 from EG = x + 72
EG = 84
399.2 divided by 1\10 =??
Answers
Answer:
3,992
Step-by-step explanation:
1/10 = 0.1
399.2/0.1 = 3,992
Answer:
3990
Step-by-step explanation:
Place the decimal to a fraction:
399.2 = 399 2/10
Simplify = 399 1/5
Put in improper fraction = 1995/5
Simplify more = 399/1 or 399
So:
399 divided by 1/10 = 3990
