1 answer:

3 0

Hello :
cot(x) = cos(x)/sin(x) .... cot²(x) = cos²(x)/sin²(x)
1-sin²(x) = cos²(x)
cot²(x)(1-sin²(x)) = ( cos²(x)/sin²(x))× cos²(x) = 1/sin²(x)

To buy both the green and the blue bikes would cost $1500. To buy the green and red bikes would cost $750. To buy all three bike

Aleksandr-060686 [28]

Green = g
Blue = b
Red = r

g+b = 1500
g+r = 750
g+b+r = 2000

in the 1st equation solve for b

g+b =1500
b = 1500-g

2nd equation solve for r

g+ r = 750
r = 750-g

now substitute the answers fro. b and r into the final equation.

g+b+r = 2000
g + 1500-g + 750-g = 2000
-g + 2250 = 2000
-g = -250
g = 250

So we k own the green bike is $250.

Blue = 1500- g
blue = 1500-250= $1250

red = 750-g
red = 750-250 = $500

a bank loaned out $13,000 part of it at a rate of 8% per year and the rest at 16% per year. if the interest received in one year

slava [35]

Answer: $725

Step-by-step explanation:

Let x represent the amount invested at 8%, then $13,000 - x is the amount invested at 16%.

0.08(x) + 0.16(13,000 - x) = 1500

0.08x + 2080 - 0.16x = 1500

2080 - 0.08x = 1500

- 0.08x = -580

x = 7250

Show the steps and name the properties you used to solve the equation below

DochEvi [55]

Answer:

0.477121=−log(3x+7)+0.30103

Step 1: Flip the equation.

−log(3x+7)+0.30103=0.477121

Step 2: Add -0.30103 to both sides.

−log(3x+7)+0.30103+−0.30103=0.477121+−0.30103

−log(3x+7)=0.176091

Step 3: Divide both sides by -1.

log(3x+7)=−0.176091

Step 4: Solve Logarithm.

log(3x+7)=−0.176091

10log(3x+7)=10−0.176091

3x+7=0.666667

3x+7−7=0.666667−7(Subtract 7 from both sides)

3x=−6.333333

−6.333333

(Divide both sides by 3)

x=−2.111111

Step-by-step explanation:hope this helps

Solve for t: t + 7 = 21 A: t= 28 B: t= 14 C: t= -28 D: t= -14

tatiyna

t + 7 = 21

---Subtract 7 from both sides

t + 7 - 7 = 21 - 7

t = 14

Hope this helps!! :)
