Answer:
She sold 72 small photos and 54 large photos.
Step-by-step explanation:
We can set a equations system with the given information. Let X be the quantity of small photos and Z large photos.
We are told that she sold 126 photos in total, so:
X + Z = 126
Also, she earned 2,250 by selling certain quantities of small photo and large photos, so:
$2,250 = $11X + $27Z
From the first equation we get that X=126-Z, replace that into the 2nd equation:
2,250 = 11(126-Z) +27Z
2,250 = 1,386 - 11Z + 27Z
2,250 - 1,386 = 16Z
864 = 16Z
Z = 864/16
Z = 54 is the number of large photos sold. Now find X.
X = 126 - Z
X = 126 - 54
X = 72 is the number of small photos sold.
In a graph, "y" axis is the vertical axis and the blue curve is your function "f(x)". So, on the blue curve, trace and mark the place that is the highest in the given window. Notice that when "x" axis (the horizontal one) is π, the blue curve reaches its highest point,
For <span>h(x)=2cos(x)+1</span>, remember that the maximum value for <span>cos(x)</span> is "1". So, the maximum value for<span>h(x)=2(1)+1<span>=3</span></span>
