Simora [160]

Answer:

Step-by-step explanation:

(-1.00000005)^n

as n becomes very large, the function increases in both positive and negative direction.

If n=1, -1.00000005

if n=2, 1.0000001

if n= 3, -1.00000015

if n=20, 1.000001

if n=21, -1.00000105

A battery was charged. When the charging began, it was 23 percent full. After 30 minutes of charging, the battery was 89 percent

AfilCa [17]

QUESTION:

A battery was charged. When the charging began, it was 23 percent full. After 30 minutes of charging, the battery was 89 percent full. how fast did the battery charge and how long did it take?

Solution :

Given

Initial amount of charge = 23%
Amount after charge = 89%

procedure

Let the rate of charging be r .

r = (change in charge level) / (time interval) = (89% - 23%) / (30 min) = 2.2 % per minute

charge = (rate of charging)(time) + (initial charge)

100% = r*t + 23%

100% = (2.2 %/min)t + 23%

Solve for t and get

t = [(100 - 23) / 2.2]

Answer = 35 min

In ΔJKL, the measure of ∠L=90°, JL = 24, LK = 7, and KJ = 25. What is the value of the sine of ∠K to the nearest hundredth?

podryga [215]

Given:

Given that JKL is a right triangle.

The measure of ∠L is 90°

The length of JL = 24, LK = 7, and KJ = 25.

We need to determine the value of sine of ∠K.

Value of sin ∠K:

The value of sin ∠K can be determine using the trigonometric ratio.

Thus, we have;

$sin \ \theta=\frac{opp}{hyp}$

Substituting $\theta=K$ , the side opposite to angle K is JL and the hypotenuse is JK

Thus, we have;

$sin \ K=\frac{JL}{JK}$

Substituting JL = 24 and JK = 25, we get;

$sin \ K=\frac{24}{25}$

Simplifying, we get;

$sin \ K=0.96$

$K=sin^{-1}(0.96)$

$K=73.74^{\circ}$

Thus, the measure of sine of ∠K is 73.74°

A triangle has a base of 3 feet, and a height of 6 feet. If its area is increased to 335 ft² by increasing the base and height b

Nonamiya [84]

So you have to find the area, because it says 335 ft². Then add 335 ft ² to the area. The answer is that sum. In otherwords, 9 plus 335
