Answer:

f( - 2) = 23

Step-by-step explanation:

f(x) = 3 {x}^{2}  - 2x + 7 \\ plug \: x =  - 2 \\ f( - 2) = 3 {( - 2)}^{2}  - 2( - 2)+ 7 \\  = 3 \times 4 + 4 + 7 \\  = 12 + 11 \\  \huge \red{ \boxed{ f( - 2) = 23}}

Illusion [34]

It is a good idea to get familiar with the operation of your calculator. If you're going to use on-line resources to work problems like this, you can make use of any of several good on-line calculators. Google and Bing search boxes will do calculations for you while observing all the rules of the Order of Operations.

The result of this computation is a number that begins 2.56.... Since the hundredths digit is more than 4, the tenths digit is rounded to the next higher value, from 5 to 6.

Rounded to tenths, 2.1√1.488 = 2.6

Answer:

The y-coordinate of F is 8.

Step-by-step explanation:

The area of the large triangle = 1/2 * base * height.

From the given coordinates:

The base of the large triangle =  x coordinate of C - x coordinate of A

= 11 - 3 = 8 units.

It's height = y coordinate of A = 12, so

Area of large triangle = 1/2 * 8 * 12 = 48 unit^2.

Using a similar calculation for the small triangle:

Base = 10 - 6 = 4 and height = k units.

So it's area = 1/2 * 4 * k = 2k unit^2.

So from given area of the shaded part:

48 - 2k = 32

-2k = -16

k = 8.

What are the y-intercept and the slope of the line represented in the graph?
sineoko [7]
Answer:

B

Explanation:

The y intercept can be read directly off of the graph, and is where the line intersects the y of the graph.

The slope (gradient) can be determined by using the equation y=mx+c, where we can substitute in the y intercept and an x and y value on the line.

y=mx+4

(2;0) is a point on the line, it is the coordinates of the x intercept (y intercept will work as well)
