^^^^^Simplify



Estimate
Step 1: Estimate the square root of 2:
1.4x1.4=1.96
1.41x1.41=1.9881
1.42x1.42=2.0164
1.9881 is closer to 2 than 2.0164
Square root of 2 is about 1.41

Step 2: Multiply the answer in step 1 by 8
1.41x8=11.28

8 times square of 2 is about 11.28
Square root of 128 is about 11.28

If you put square root of 128 in a calculator it would say 11.31 something...

Hourly rate:
39(1.3r) = 541.80
(hours times hourly rate equals profit)

then solve
1.3r = 13.89
r = 10.69

the hourly rate is $10.69


to answer the bottom question, 390 + 117 = 507, but that’s not close to 541.80 so I have no idea what they’re asking there

The annual interest rate on a $10,000 loan is 18%. The exponential function that represents this is y = 10000(1.18t). Write the
Yuki888 [10]

Answer:

y=10000(1.015)^{12t}

option-B......Answer

Step-by-step explanation:

We are given

amount taken for loan =$10000

so, P=10000

annual interest rate =18%

r=0.18

now, we can use formula

y=P(1+\frac{r}{n} )^{nt}

Since, it is compounded monthly

so, n=12

we can plug values

y=10000(1+\frac{0.18}{12} )^{12t}

y=10000(1.015)^{12t}

Question Solve for x 3x = x + 8​
Viktor [21]

Answer:

x=4

Step-by-step explanation:

here's our equation: 3x=x+8

Our goal: to isolate x onto one side with nothing else on that side.

x is on both sides; we can subtract x from both sides to make the variables and numbers be on different sides

2x=8

Now we can divide by 2

x=4

Hope this helps! :)
