Solve this equation for x 0.95 = log x
Lelechka [254]

Answer:

8.91

Step-by-step explanation:

Given:  0.95 = log x,

we can conclude that:

    0.95            log x

10             =  10

                                                          0.95

which in turn is equivalent to x = 10            whose value is  8.91

Katie invests $5,000 in an account earning 4% interest, compounded annually for 5 years. Two years after Katie's initial investm
Lyrx [107]
Emily earned $166 more in her account than Katie.

We use the compound interest formula for both of these:

A=p(1+r)^t

For Katie's deposit:
A=5000(1+0.04)^5=5000(1.04)^5 = 6083.26

This gives Katie 6083.26-5000 = 1083.26 in interest (1083, to the nearest dollar).

For Emily's deposit:
A=10000(1+0.04)^3=10000(1.04)^3=11248.64

This means she earned 11248.64-10000=1248.64 in interest (1249, to the nearest dollar).

The difference in interest is given by 1249-1083=166

Flock of birds is flying south, toward the equator, at an hourly rate. A scientist created the function f(x)=−60x+1320 to repres
lina2011 [118]

Answer: First and last option

The birds began 1320 miles from the equator.

The birds are flying toward the equator at a rate of 60 mph.

Step-by-step explanation:

Note that the function f(x) is a linear function.

f (x) = - 60x + 1320

If x represents the number of hours and f(x) represents the distance from the equator, then x = 0 means that the first hour has not yet elapsed.

When x = 0 then:

f (0) = -60 * 0 +1320\\f (0) = 1320.

This means that the initial distance at which the birds of the equator are located is 1320 miles.

Then when x = 1 then:

f (x) = -60 * 1 + 1320\\f (x) = -60 +1320

When x = 2 then:

f (x) = -60 * 2 + 1320\\f (x) = -120 +1320

As x increases by one unit then the distance of the birds to the equator decreases by 60 miles. This means that birds travel at a speed of 60 miles per hour
