Multiplying the values given above we obtain a value of 0.01386. In scientific notation, 1.386 x 10^-2. The significant figures of a number are digits that carry meaning contributing to its measurement resolution. From the multiplicand and the multiplier, the least number of significant significant figure would be one. Therefore, we write as

1.0 x 10^-2

The function f(x) = –x2 + 20x – 75 models the profit from one customer, in dollars, a shop makes for printing photos, where x is

trasher [3.6K]

The function is graphed as shown below

Part A:

We use the formula $- \frac{b}{2a}$ to find the vertex of the function. A quadratic function of the form of $a x^{2} +bx+c$ and equating this form to the given function $- x^{2} +20x-75$ , we have
$b=20$ and $a=-1$ .

Substituting $a$ and $b$ into the vertex formula, we have
$x=- \frac{20}{2(-1)}=10$ , as shown in the graph

This calculation means that the highest profit is achieved when the number of photo printed equals to ten photos

Part B:

We can find solution to this equation by factorising

$- x^{2} +20x-75=0$
$-( x^{2} -20x+75)=0$
$x^{2} -20x+75=0$
$(x-5)(x-15)=0$
$x=5$ and $x=15$ , as shown in the graph

The two values means that the company makes no profit when they either produce 5 or 15 photos

Three vertices of a rectangle have coordinates (3,4), (5,-4), and (-7,-7). What is the y coordinate of the fourth vertex?

erica [24]

- Three vertices of a rectangle have coordinates (–3, 1), (7,1), and (7, –4). ... What are the coordinates of the fourth vertex of the rectangle? A. (–3, –4) B. (–3, –1) C. (7, –3) ... go straight down basically -3 there has to be two -3 for x coordinate and two 7 for y coordinate ... Mathematics; 5 points; 37 seconds ago.

If a line has a slope of -4 and a u intercept of 1, which of the following is it's graph?

3241004551 [841]

Well. I can't see the picture. But it would be decreasing at a rate of 4 so pick a point on the any line move over to the right one, then down four. And for the y intercept the line would intersect the y axis at positive one. Sorry if that's confusing

Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x+2) ?

Ahat [919]

Adding a value to the X value shifts the graph that many units to the left.

X+2 adds 2 to x, so the graph would shift 2 unites to the left.

The answer is:

The graph of g(x) is the graph of f(x) translated 2 units left.
