QR- 2(9-3)=

2(6)=12

MP- 9+5=14

QRS=MNP

12/8, 15/10, 21/14= 3/1

Scale Factor is 3:1 or 3 to 1

The maximum value of the function: f(x)= -5 x ^2 +30x-200 is?

VARVARA [1.3K]

Answer:

$\displaystyle - 155$

Step-by-step explanation:

we are given a quadratic function

$\displaystyle f(x) = - 5 {x}^{2} + 30x - 200$

we want to figure out the minimum value of the function

to do so we need to figure out the minimum value of x in the case we can consider the following formula:

$\displaystyle x _{ \rm min} = \frac{ - b}{2a}$

the given function is in the standard form i.e

$\displaystyle f(x) = a {x}^{2} + bx + c$

so we acquire:

b=30
a=-5

thus substitute:

$\displaystyle x _{ \rm min} = \frac{ - 30}{2. - 5}$

simplify multiplication:

$\displaystyle x _{ \rm min} = \frac{ - 30}{ - 10}$

simply division:

$\displaystyle x _{ \rm min} = 3$

plug in the value of minimum x to the given function:

$\displaystyle f (3)= - 5 {(3)}^{2} + 30.3 - 200$

simplify square:

$\displaystyle f (3)= - 5 {(9)}^{} + 30.3 - 200$

simplify multiplication:

$\displaystyle f (3)= - 45 + 90- 200$

simplify:

$\displaystyle f (3)= - 155$

hence,

the minimum value of the function is -155

The cost of attendance at State College is $19,500 for the first year. Devise a periodic savings plan that will allow you to mak

nignag [31]

Simple interest rate for one year = 1.5%
simple interest rate over 5 years = 1.5 x 5 = 7.5%

100% + 7.5% = 107.5%
107.5% = $19500
1% = 181.3953
100% = $18140.50

He needs to put in $18140.50 so that he can get $19,500 at the end of 5 years.
