Answer:

-4/5 or -0.8

Step-by-step explanation:

Slope is the change in y over the change in x.

m = (y₂ − y₁) / (x₂ − x₁)

Here, the first point (x₁,y₁) is (6,-3).  The second point (x₂,y₂) is (-4,5).

m = (5 − (-3)) / (-4 − 6)

m = 8 / -10

m = -4/5 or -0.8

Can someone help me figure out the answer?
Marina86 [1]

Answer:

f(t) = 5×0.87^t

Step-by-step explanation:

The general form for an exponential function described in this fashion is ...

... f(t) = (starting value) × (1 + (percent change))^t

Here, the "percent change" is -13%, or -0.13.

Then the value (1 + percent change) is (1 + (-0.13)) = 0.87. Putting this and the starting value into the form above, we have ...

... f(t) = 5 × 0.87^t

Ainat [17]

Answer:

read.

Step-by-step explanation:

The popularity of the Gutenberg press in Europe made books more accessible and motivated people want to learn how to READ.

This is evident in the fact that Johannes Gutenberg who was widely known as a printer was famous for inventing a means of producing books at a cheaper cost and portable size that is also durable and easy for distribution.

The result of this invention led to an increase in the availability of books and thereby enhance and motivate more people, not just the elites, to have access to books and READ them.

if one store is selling 3/4 of a bushel of apples for 9 dollars and another store is selling 2/3 of a bushel of a apple for 9 do
fredd [130]
3/4 of a bushel is 75%, 2/3 of a bushel is 66.67% about. Being that both cost $9 the first store who is selling 3/4 of a bushel is a better deal because you get more for what you pay for.

The front of a storage bunker can be modeled by y=-5/216(x-72)(x+72), where x and y are measured in inches. The x axis represent
german
As far as I can make out this one.

the bunker is a 3D object, it has a height, with and length, however we're only concerned with the 2D front face, which has a length and width only.

we know the x-axis is the ground level, so the y-axis must be the scale for the length.

if we can find, using the provided model, the x-intercepts, namely where the x-axis gets touched, we can just get the distance between them and that's the ground level width.

keeping in mind that when the graph touches the x-axis, an x-intercept, "y" is 0.

\bf y=-\cfrac{5}{216}(x-72)(x+72)\implies \stackrel{y}{0}=-\cfrac{5}{216}(x-72)(x+72)
\\\\\\
0=\stackrel{\textit{difference of squares}}{(x-72)(x+72)}\implies 0=x^2-72^2\implies 72^2=x^2
\\\\\\
\pm\sqrt{72^2}=x\implies \pm 72=x

now, the distance from (-72, 0) and (72, 0) is just 72 +72, or 144.
