Konichiwa~! My name is Zalgo and I am here to help you out today. If f were to equal -3, first we need to put -3 into the equation. It would look like "f(-3)=x^2". The answer to that equation is 9.

I hope that this helps! :T

For the trinomial ​3x^2 + 22x + 7, choose two numbers whose product is 21 and whose sum is 22
Lesechka [4]

Answer:

When a trinomial is in the form of ax2 + bx + c, where a is a coefficient other than 1, look first for common factors for all three terms. Factor out the common factor first, then factor the remaining simpler trinomial. If the remaining trinomial is still of the form ax2 + bx + c, find two integers, r and s, whose sum is b and whose product is ac.

Find the measure of a central angle that intercepts an arc of 3 inches in a circle whose radius is 8 inches.
Tresset [83]

Answer:

option (A)

central angle = 0.375 rad

Step-by-step explanation:

Given in the question,

radius of the circle = 8 inches

arc of the circle = 3 inches

To find,

measure of a central angle

Central angles are subtended by an arc between those two points.

Formula to use:

<h3>     s = (r) (θ)</h3>

<em>where r = radius </em>

<em>            s = arc length </em>

<em>            θ = angle in radians</em>

<em />

Plug in the values in the equation

<h3>3 = (8) (θ)</h3><h3>θ = 3/8 </h3><h3>0.375 rad</h3>

Reasoning point F lies on EG and point M lies on EN. If F,E, and M are collinear, what must be true of these rays.
almond37 [142]
This means that all of the points are co-linear. This is because if EG is a segment that contains F, and EN is a segment that contains M, then there can be two different segments. However, for a point F on the first segment and a point M on a second segment be in the same line as an end point of one of the segments, the segments have to be co-linear. They overlap.
