Answer:

Step-by-step explanation:

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

I need a equation for my parabola! I tried so many times and got it WroNg-

rodikova [14]

Answer:

Step-by-step explanation:

Not QUITE a parabola . but up until y = 4 it is close

Vertex = (-7-10)

Vertex form of parabola

y = a ( x+7)^2 -10 find a integer-coordinat point to calculate 'a'

I'll use -18,0

0 = a(-18+7)^2 -10

0 = 122 a -10 a = 10/122

y = 10/122 (x+7)^2 - 10 see graph below:

Solve 2cos^2x+5cosx+2=0

Nuetrik [128]

$2cos^2x+5cosx+2=0\\
x\in\\
\Delta=b^2-4ac\\
\Delta=9\\
\sqrt{\Delta}=3\\
cosx=1\\
or\\
cosx=-6\\
-6\notin\\$

Then using trygonometric table or a graph we read that:
$cosx=1\Leftrightarrow(x)=0$

Period of cosinus function = 2π
So the last answer is $x=0+2k\pi\\$
