Answer:
10 i sqrt 2
Step-by-step explanation:
i indicates that it is an imaginary number. this is because 200 is negative.
The simplified form of the given square root number is 10i√2. Therefore, the correct answer is option D.
The given square root number is √-200.
The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.
Here, 200 = 2×2×2×5×5
Thus, √-200=√-2×2×2×5×5
=2×5×i√2
= 10i√2
Therefore, the correct answer is option D.

Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound. How much of each brand of coffee is needed to make 5 pounds that will cost
$6.75/pound?
A. 0.8 pounds Brand A, 4.2 pounds Brand B
B. 2.7 pounds Brand A. 2.3 pounds Brand B
C. 4.2 pounds Brand A. 0.8 pounds Brand B
D. 2.3 pounds Brand A. 2.7 pounds Brand B
Answers
Answer:
C. 4.2 pounds Brand A. 0.8 pounds Brand B
Step-by-step explanation:
How much of each brand of coffee is needed to make 5 pounds that will cost
$6.75/pound?
Let the number of pounds for Brand A = x
Let the number of pounds for Brand B = y
Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound.
$7 × x + $5.40 × y = $6.75 × 5
7x + 5.40y = 33.75.......Equation 1
x + y = 5 .......Equation 2
x = 5 - y
7(5 - y)+ 5.40y = 33.75
35 - 7y + 5.40y = 33.75
35 - 33.75 = 7y - 5.40y
= 1.25 = 1.6y
y = 1.25/1.6
y = 0.78125 pounds.
Approximately to the nearest whole number, Brand B = 0.8 pounds.
x = 5 - y
x = 5 - 0.8 pounds
x = 4.2 pounds
Brand A = 4.2 pounds

if cos(x) = -1/4 and tan(x) < 0, what is sin(2x)
Answers
Answer:
B is correct: (-sqrt15)/8
Step-by-step explanation:
The value of the x is 104.5° then the value of the sin 2x is -0.49. Then the correct option is B.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
If cos(x) = -1/4 and tan(x) < 0
Then the value of the x will be
[tex]\begin{aligned} \cos x &= - \dfrac{1}{4}\\\\x &= \cos^{-1} \dfrac{-1}{4}\\\\x &= 104.5^o \end{aligned}[/tex]
Then the value of the sin 2x will be
[tex]\sin 2x = \sin 2*104.5^o\\\\\sin 2x = \sin 209^o\\\\\sin 2x = -0.4848 \approx 0.49[/tex]

Marissa has $4.70 in quarters and dimes. If she has 9 more quarters than dimes, how many of each coin does she have?
dimes
quarters
Answers
Answer:
22 dimes
10 quarters
Step-by-step explanation:
$4.70 = 0.25(q + 9) + 0.1d
4.7 = 0.25q + 0.25(9) + 0.1d
4.7 = 0.25q + 2.25 + 0.1d
2.45 = 0.25q + 0.1d
24.5 = 2.5 + d
22 = d = 22 dimes
$4.70 = 0.25(q + 9) + 0.1(22)
4.70 = 0.25q + 0.25(9) + 2.2
4.70 = 0.25q + 2.25 + 2.2
4.70 = 0.25q + 2.25 + 2.2
4.70 = 0.25q + 4.45
0.25 = 0.25q
1 = q
1 q + 9 q = 10 quarters
Check:
$4.70 = 0.25(q + 9) + 0.1(d)
$4.70 = 0.25(1 + 9) + 0.1(22)
$4.70 = 0.25(10) + 0.1(22)
$4.70 = 2.5 + 2.2
$4.70 = 4.7
