Simplify √-48
1) -4√3
2) 4√-3
3) 4i√3
4) 4√3i
We can change the negative sign into i instantly as sqrt-1 is i.
With this the problem simplifies to sqrt48*i.
Now sqrt48=sqrt4*sqrt4*sqrt3=2*2*sqrt3
So the final product is 4sqrt3*i=4isqrt3.
Thus choosing choice 3 :)

Answer:
x = 4
Step-by-step explanation:
-5w + 7 - w + 4 = -13
-5w - w + 7 + 4 = -13
-6x + 11 = -13
-6x = -13 - 11
-6x = -24
-6x/-6 = -24/-6
x = 4

Order from least to greatest.
68%, 0.687, 20
Answer:
20, 68%, 0.687
Step-by-step explanation:
If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.

Find the area of figure ABCDE if angles A, B, and C are right triangle
Answer:
85 ft.
Step-by-step explanation:
8*10=80 (the value of the the rectangle by itself)
then we take the values we are given and find the width and height of the triangle. Knowing it is a right triangle, we perform two equations,
15-10 (the total length of the polygon) 5 ft
and
8-6 (to find the height of the triangle, using the length where the hypotenuse of the triangle cuts off the rectangle) 2 ft
With this, we now have the length and width of the right triangle, and multiply them together to get 10. Because that formula only works on rectangles and squares, but we know that the triangle is a right triangle, we divide the 10 in half to get 5, which is the area of the triangle. Together, the value of the area for the rectangle and the triangle together result in 85 ft (remember to label units when in a written test!)

Roy has $30 in a savings account. The interest rate is 10% per year and is not
compounded. How much will he have in 4 years?
Answer:
$43.92
Step-by-step explanation:
1st year:
30 x 10% = 3
30 + 3 = 33
2nd year:
33 x 10% = 3.3
33 + 3.3 = 36.3
3rd year:
36.3 x 10% = 3.63
36.3 + 3.63 = 39.93
4th year:
39.93 x 10% = 3.99
39.93 + 3.99 = 43.92

Which graph represents exponential decay?
Answer:
c
Step-by-step explanation:
Edge 2020 - 2021
Good luck on your quiz :)
Graph (a) represents an exponential decay.
Here, two graph are shown and we have to check which represent exponential decay.
What is exponential decay?
Exponential decay occurs when a quantity decreases by the same factor over equal intervals of time.
Now,
From the graph, we have
In graph (a), as x increases the function decreases.
Hence this graph shows exponential decay.
In graph (b), as x increases the function increases.
So, Graph (a) represents an exponential decay.

would this be the right answer??
Answer:
no your answer is wrong. the answer is 15.6
Step-by-step explanation:
it is a 30-60-90 degree triangle and as per the property ..
the side opposite to 30 degree angle is half of hypotenuse( I. e half of 18 that is 9)
the side opposite to 60 degree angle is √3/2 the hypotenuse.
that is √3/2 * 18
that is √3 * 9
that is 1.73 multiplied by 9 .....(as value of √3 is 1.73)
that is 15.57
rounding it to the nearest tenth it becomes 15.6
answer is 15.6 not 20.1
