How do I rewrite In 7=y as an exponential equation? I kind of forgot how to do these

Marina CMI [18]

Answer:

$e^y=7$

Step-by-step explanation:

$ln(7)=y$

$e^{ln(7)}=e^y$

$7=e^y$

Raising e to both sides cancels out the natural logarithm on the left side and we have our exponential form. This works with other bases (recall that the natural logarithm, ln, has base e)

The equations of two functions are y =-28x + 8 and y=-29x + 7. Which function is changing more

irinina [24]

Answer:

$y=-29x+7$ is changing more quickly.

Step-by-step explanation:

This is because the equation $y=-29x+7$ has a larger slope. The speed of change is determined entirely by the slope; the larger the slope, the faster the line goes up or down. It doesn't matter if it's negative or positive. -29 is the slope of the equation.

What is the slope of the line?

Scorpion4ik [409]

Answer:

Slope is technically 1, because it implies that it's going up one and over to the right one. Also in slope-intercept form it would look like this

y = x + 1.

Step-by-step explanation:

Hope this makes sense :)

Lady bird [3.3K]

Answer:

0.04,0.25.0.52

Step-by-step explanation:

Given that you throw a dart at a circular target of radius 10 inches.

Assuming that you hit the target and that the coordinates of the outcomes are chosen at random,

probability that the dart falls

(a) within 2 inches of the center

Here favourable region has area of a circle with radius 2 inches and sample space has area of 10 inches

Prob = $\frac{\pi *2^2}{\pi *10^2} \\\\=\frac{1}{25}$

(b) within 2 inches of the rim.

For within two inches from the rim we have to select area of the ring i.e. area of big circle with 10 inches - area of smaller circle with 10-2 inches

Prob= $\frac{\pi * *8^2}{\pi*10^2} \\=0.64$

c) within I quadrant

area of I quadrant / area of circle=0.25

d) within I quadrant and within 2 inches of the rim

= I quadrant area + 2 inches ring area - common area

= $\frac{\pi*10^2/4 + pi*(10^2-8^2) - \pi(10^2-8^2)/4}{\pi*10^2} \\=\frac{25+36-9}{100} \\=0.52$
