Vikki [24]4 years ago
3 0

Answer:

B, f(x)=-7x^2-x+2

Step-by-step explanation:

Quadratic formulas must have only one degree which must also always be to the second power, and they cannot have a 0 as a coefficient, so that is the only sensible answer.

If y = 8x − 2, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
Nataly [62]
You just need to try with all of the pair f.ex
0,-2 -> put 0 in the x-> y=8*0-2=-2 so ok it is q possible pair of the function..
You try every pair till you find set where all the pairs fit
So set 1
1 and 6: 8*1-2=6 ok
2 and 14 : 8*2-2=14 ok
Hope I could help

If the lateral area of a cone is 587pi cm^2and the radius is 32cm what is the slant height?
Serggg [28]
The formula for this is an easy, straightforward one:  A= \pi rl where r is the radius and  l is the slant height.  You have your area and your radius, so solve it for slant height.  587= \pi 32l and l= \frac{587}{32 \pi }.  Multiply that pi in to the 32 and then divide that into 587 and you'll get 5.8

Find the value of x. A. 53–√ in B. 241−−√ in C. 55–√ in D. 9
castortr0y [4]

Answer:

<h2>x = 5√3 inches</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

{a}^{2}  =  {b}^{2}  +  {c}^{2}

where a is the hypotenuse

Substitute the values into the above formula

The hypotenuse is 10 inches

We have

{10}^{2}   =  {5}^{2}  +  {x}^{2}

{x}^{2}  =  {10}^{2}  -  {5}^{2}

{x}^{2}  = 100 - 25

{x}^{2}  = 75

We have the final answer as

<h3>x = 5√3 inches</h3>

Hope this helps you

Find the slope of every line that is parallel to<br> the graph of the equation.<br> Y=1/4=2
polet [3.4K]

Answer:

m=1/2

Step-by-step explanation:

This equation is in slope intercept form. The slope-intercept form of a linear equation is:  

y

=

m

x

+

b

Where  

m

is the slope and  

b

is the y-intercept value.

y

=

1

2

x

+

2.3

Therefore, the slope of the line in the problem is:  

m

=

1

2

Two parallel line, by definition, will have the same slope

Therefore, the slope of any line parallel to the line in the problem is also:

m

=

1

2
