Evaluate f(t)=-2t2+ 1 for f(-3).

podryga [215]

Answer:

7

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

$f(-3)=-2(-3) +1$

Second, multiply -2 and -3 to get 6:

$f(-3)=-2(-3)+1$ ⇒ $f(-3)=6+1$

Third, add 6 and 1 to get your answer:

$f(-3)= 6+1$ ⇒ $f(-3)=7$

How to find the median

KengaRu [80]

We can find the median by using the formula:

(N+1/2) th item

For example:

Given data: 4,6,3,5,7

We have to arrange the data into ascending order:

=3,4,5,6,7

N(total no of items)=5

Now,

Median=(N+1/2)th item

 =(5+1/2) th item

 =(6/2) th item

 = 3rd item

Median=5

Hope it helps

Good luck on your assignment

Mario took clothes to the cleaners three times last month. first, he brought 3 shorts and 1pair of slacks and $10.96. then, he b

valina [46]

Let us say that:

x = cost of shorts

y = cost of slacks

z = cost of sports coat

From the given statements, we can create the following equations:

eqtn 1: 3 x + y = 10.96

eqtn 2: 7 x + 2 y + z = 30.40

eqtn 3: 4 x + z = 14.45

Rewrite eqtn 1 explicit to y:

y = 10.96 – 3 x --> eqtn 4

Rewrite eqtn 3 explicit to z:

z = 14.45 – 4x --> eqtn 5

Plug in the values of y (eqtn 4) and z (eqtn 5) to eqtn 2:

7 x + 2 (10.96 – 3 x) + 14.45 – 4 x = 30.40

7 x + 21.92 – 6 x + 14.45 – 4 x = 30.40

- 3 x + 36.37 = 30.40

- 3 x = - 5.97

x = 1.99

Eqtn 4:

y = 10.96 – 3 x

y = 10.96 – 3 (1.99)

y = 4.99

Eqtn 5:

z = 14.45 – 4x

z = 14.45 – 4 (1.99)

z = 6.49

Therefore each shirt cost $1.99, each slacks cost $4.99, and each sports coat cost $6.49.
