Asap! find the length of the arc

Fantom [35]

Answer:

A. $\frac{21}{4} \pi\ \space\ in$

Step-by-step explanation:

The formula for arc length is:

arc length = rθ

where:

r is the radius = 7 in

θ is the central angle in radians = 135 × $\frac{ \space\ \pi\ }{180}$ = 3/4 π

Substituting these values into the formula:
arc length = 7 in × 3/4 π

= $\frac{21}{4} \pi\ \space\ in$

Answer:

Solving the inequality $3x -2 < 4$ we get $\mathbf{x$

Option D is correct option.

Step-by-step explanation:

We need to solve the inequality $3x -2 < 4$ and find value of x

Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

$3x -2 < 4$

Adding 2 on both sides

$3x -2+2 < 4+2\\3x < 6$

Now, we will divide 3 on both sides

$\frac{3x}{3}$

So, we get x < 2

Solving the inequality $3x -2 < 4$ we get $\mathbf{x$

Option D is correct option.

Kronos Industries bought a desktop for $3,000. It is expected to depreciate at a rate of 10% per year. What will the value of th

kolbaska11 [484]

Answer:

$1968

Step-by-step explanation:

It will depreciate by 10% 4 times, which means that the result in the end will be $3000 * (100% - 10%) * (100% - 10%) * (100% - 10%) * (100% - 10%), or, put simply, x = $3000 * (0.9)⁴.

Power: x = $3000 * 0.6561

Multiply: x = 1968.3 ≈ $1968

1000 was invested at 5.5% interest, compounded annually. After sometime the amount had grown to 1550. How long was the money inv

scZoUnD [109]

compound interest equation for annually compounded

$A=P(1+r)^t$

A=final amount

P=principal

r=rate in decimal

t=time in years

given that

A=1550

P=1000

r=5.5%=0.055

find t

$1550=1000(1+0.055)^t$

divide both sides by 1000

$1.55=1.055^t$

take ln of both sides

$ln(1.55)=ln(1.055^t)$

use ln rule $ln(a^b)=b(ln(a))$

$ln(1.55)=t(ln(1.055))$

divide both sides by ln(1.055)

$\frac{ln(1.55)}{ln(1.055)}=t$

using a calculator, we get that t=8.18544 yrs

so about 8.2yrs
