D because using the y=mx+b the slope(mx) is 1/2 (rise over run) and it starts at point 0,-2(b) since y is always 0 and -2 is the x value

Four pounds of apples cost $5. Eght pounds of apples cost $10. If the total cost of apples, y varies directly with the

dlinn [17]

Well the cost of the apples can be found by dividing the price by the amount bought. ($5/4 or $10/8 = $1.25/lb). If you want to find the amount for 6 pounds just multiply it by the individual cost (6x$1.25= $7.50)

A wildlife biologist examines frogs for a genetic trait that is linked to sensitivity to an industrial toxin in the environment.

Dvinal [7]

Answer:

Step-by-step explanation:

Usually, when there is contamination the smallest amount can have huge ramifications in the data collected. In this scenario, if in a "clean" environment the trait is found in 2/10 frogs then anything above this number should be considered contaminated. This is because data above this ratio would be considered uncommon or rare and this unique occurrence can be most likely tied to the only new factor which would be the contamination. Therefore the minimum number of frogs with this trait in the sample would be 3.

If an object is dropped from a height of 55 feet, the function d=-16t^2+55 gives the height of the object after t seconds. Graph

Ymorist [56]

Notice, it hits the ground when d = 0, thus

$\bf \stackrel{d}{0}=-16t^2+55\implies 16t^2=55\implies t^2=\cfrac{55}{16}\implies t=\sqrt{\cfrac{55}{16}}$

that's when.

as far as its graph, is more or less like the picture below, now, notice that if we put the quadratic in "vertex form", it'd look like

$\bf d=-16t^2+55\implies d=-16(t-\stackrel{h}{0})^2+\stackrel{k}{55}\qquad vertex~(h,k)$

so its vertex is at (0, 55), so just pick one point to the left of the vertex, and one to the right of the vertex, and draw it away
