Answer:
C.4
Step-by-step explanation:
Since the values are of the same base....
we add the powers..because its multiplication...
;2^(-1/3 + 7/3)
;2^(6/3) = 2^2
;Ans = 2^2 = 4
For cos(2x) * (2cos(x) + 1) = 0, use the double angle identity for cos(2x), which is cos^2 x - sin^2 x = cos^2 x - (1-cos^2) = 2cos^2 x - 1.
So we have (2cos^2 x - 1)(2cos x + 1) = 0. So 2cos^2 x -1 = 0 or x = 0 and 2pi.
For 2sec^2 x + tan^2 x - 3 = 0, use the identity sec^2 x = tan^2 x + 1, so we have
2(tan^2 x + 1) + tan^2 x - 3 = 0 or
<span>2tan^2 x + tan^2 x - 1 = 0 or
</span>3 tan^2 x = 1.
So x = pi/2, pi/2 + pi = 3pi/2.
Answer:
34
Step-by-step explanation:
You can solve this problem by finding the volume of the candle first. The formula for rectangular prism is multiplying all three of its dimension. In this case, you would multiply 3, 10, and 4 together to get 120 cm^3. Assuming the question meant "the company used 4080 cm^3 of wax", divide 4080 by 120 to see the number of candles the company made, which is 34.
Answer:
The answer to your question is Advance = $35 and same-day = $40
Step-by-step explanation:
Advanced = a
Same-day = s
Equations
a + s = 75 ----- (I)
20a + 35s = 2100 ----- (II)
Process
1.- Solve the equations by elimination.
Multiply equation I by -20
-20a - 20s = -1500
20a + 35s = 2100
Simplify
0 + 15s = 600
Solve for s s = 600/15
s = $ 40
Substitute "s" in equation I to find "a"
a + 40 = 75
Solve for a
a = 75 - 40
a = 35
I believe the correct answer from the choices listed above is the last option. The function that represents the total cost to build the dog house would be <span>c(p)=12p+65. Hope this answers the question. Have a nice day.</span>
