Answer:
a) 16 meters ; b) 8 seconds
Step-by-step explanation:
The function can be represent with a parabola whose vertex is its maximum point
for answer the first question we have to find the y of the vertex
first of all we have to find the x
Vertex (x) = -b/2a = -8/-2 = 4
if we substitute t with 4, we can find the y
Vertex (y) = -(4^2) + (8*4) =
= -16 + 32 = 16
so the answer is 16 meters
for answer the second question we have to find where the parabola intercepts the x axis, that means solve the associated equation:
-t^2 + 8t = 0
t^2-8t = 0
t(t-8) = 0
t = 0
t = 8
the parabola intercept the x axis in (0,0) and in (8,0)
if we find the distance between this two points we can answer to the question
8-0 = 8 seconds

HELP ME WITH THIS PLEASE.
THANKS LOVE U GUYS SO MUCH.
Answer:
48.
Step-by-step explanation:
1). <C = 74 because it forms a supplemetary angle 180- 106 = 74.
2). We know that the sum of all the angles in a triangle is 180 so we need to add them.
3). 4y + 3y +22 + 74= 180
4). simplify 7y +96=180
5). isolate y so we must subtract 96 from either side.
6). 7y= 84 now divide by 7 on each side. 84/7 = 12.
7). Now we know y = 12 and that angle A is equal to 4y.
8). <A = 4(12) now distrubute
9). <A= 48 degrees

→ Half the second term and place it in the bracket
( x - 3 )²
→ Square -3
- ( 3 )² = -9
→ Place this outside the brackets along with plus 10
( x - 3 ) ² - 9 + 10

Answer:
201.53[tex]m^{2}[/tex]
Step-by-step explanation:
That is a hexagonal pyramid, which means it consists of one hexagon and six triangles.
Let's first find the hexagonal base.
The formula to find the area of a hexagon is [tex]\frac{3\sqrt{3}}{2}a^{2}[/tex], where a is the length of one side of the hexagon. In this question, a = 6m
Solve that to find that the area of the hexagon is 93.53m^2.
Now, on to the triangles. The area of one triangle is the base times the height, then halved. We know that the base of the triangle is 6m as it shares the base with a side of the hexagon, and the question states that the height is also 6m.
6 * 6 = 36
36 / 2 = 18
Hence, the area of one triangle is 18m^2
However, there are six triangles - not just one!
6 * 18 = 108
Adding everything up:
93.53 + 108 = 201.53
The answer is 201.53m^2

Floyd decides to invest $1,000,000 in a 20-year annuity that earns 4.6% APR compounded monthly. How much money will Floyd be paid each month from this annuity?
Answer:
$6380.38
Step-by-step explanation:
Floyd will be paid $2,504,880 each month.
What is Compound Interest?Compound interest is an interest of interest to the principal sum of a loan or deposit. The concept of compound interest is the interest adding back to the principal sum so that interest is earned during the next compounding period.
Given that Floyd invests $1,000,000 in a 20-year annuity that earns 4.6% APR compounded monthly.
A = P(1+r)ⁿ
A = 1,000,000(1+0.046/12)²⁰⁽¹²⁾
A = 2,504,880
Hence Floyd will be paid $2,504,880 each month.

Answer:
You have to add water.
Step-by-step explanation:
I hope this helps! Have a great rest of your day!
The decision to add water to meet the 4 cup mark of water would be:
Yes, the water must be added.
What is volume?"Volume" is described as the measure of a space that consists of length along with height and width.
Given that,
1 liter of water contains 1000 ml.
The capacity of a standard cup is 236.59 ml
If we take 4 cups, the total volume equals:
= 4 × 236.59
= 946.36 ml
Therefore, .23 cups or 53.64 ml of water would be required to be added.
