Answer:

m∠1 = 25° (opposite angles are congruent)

m∠2 = 87° ⇒ 180 - (25 + 68)

m∠3 = 68° ⇒ 180 - (87 + 25)

Hope this helps!

The following function represents the value of a house, in dollars, after x years: f(x) = 242,000(1.04)x What does 1.04 represen

zmey [24]

The number 1.04 represents the rate at which the house appreciates, or increases in its price annually.

As according to the values of an exponential equation, which is represented by this: y=ab^x, the a value represents the original price, the b value represents the rate of growth/decay (if growth, you add 1 to the rate, if decay, you subtract the rate from 1), and x represents the amount of times it decays or grows.

As according to the function <span> f(x) = 242,000(1.04)^x, 242,000 is the original price and 1.04 is the rate of growth since 1 has been added to the the 4% annual growth.</span>

If the units for x are years, and x = 5 represents the year 2015, what is the y-value for 2010?

Darya [45]

<u>Given</u>:

The given graph passes through the points (-3,4) and (3,2)

The x - axis represents the years. The value x = 5, year 2015.

We need to determine the y - value for 2010.

<u>Slope</u>:

The slope of the line can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the points (-3,2) and (3,2), we get;

$m=\frac{2-4}{3+3}$

$m=\frac{-1}{3}$

Thus, the slope of the line is $m=\frac{-1}{3}$

<u>y - intercept:</u>

The y - intercept in the graph is the point in the line that crosses the y - axis.

Thus, from the graph, it is obvious that the y - intercept is b = 3.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

$y=mx+b$

Substituting the values, we have;

$y=-\frac{1}{3}x+3$

Thus, the equation of the line is $y=-\frac{1}{3}x+3$

<u>The y - value for 2010:</u>

Since, it is given that x = 5 represents 2015 and 2010 is 5 years before 2010.

Hence, the value of x for 2010 is given by

$x=5-5=0$

Thus, x = 0 represents the year 2010.

To determine the y - value, let us substitute x = 0 in the equation $y=-\frac{1}{3}x+3$ , we have;

$y=-\frac{1}{3}(0)+3$

$y=3$

Thus, for 2010 the value of y is 3.

it took kris 14 hours to drive to San Francisco. He drove 75 miles an hour. He took a 2 hour break in Las Vegas. How many miles

kogti [31]

Answer:

900 miles

Step-by-step explanation:

Given:

Total time taken by Kris is 14 hours.

Speed of Kris is, Speed = 75 mph

Time spent while taking a break is 2 hours.

So, time Kris drove his vehicle is given as the difference of total time and time spent in break. Therefore,

Actual time of driving = 14 - 2 = 12 hours.

Now, distance traveled is given as the product of speed and time of driving.

∴ Distance = Speed $\times$ Time

Distance = $75\times 12=900\ mi$

Therefore, Kris drove 900 miles.
