A Function is defined as K(x)= 2x^2 -5x +3.The value of K(-3) is

nadya68 [22]

Given that $K(x)= 2x^2 -5x +3$ as a function, the value of K(-3) can be found by substituting x for -3 into the function which will give us: $\mathbf{K(-3) = 36}$

Given the function, $K(x)= 2x^2 -5x +3$ , to find the value of K(-3), substitute -3 for x into $K(x)= 2x^2 -5x +3$ .

Thus, substitute:

$K(-3)= 2(-3)^2 -5(-3) +3\\\\K(-3) = 18 + 15 + 3\\\\\mathbf{K(-3) = 36}$

Therefore, given that $K(x)= 2x^2 -5x +3$ as a function, the value of K(-3) can be found by substituting x for -3 into the function which will give us: $\mathbf{K(-3) = 36}$

Add the two complex numbers 6 + 7i and 10 + 2i. Write your answer as a complex number in standard form, a + bi.

lina2011 [118]

1. The complex number 6 + 7i has

real part 6;
imaginary part 7.

2. The complex number 10 + 2i has

real part 10;
imaginary part 2.

3. When we add two complex numbers, we add real parts and imaginary parts separately:

(6+7i)+(10+2i)=(6+10)+(7+2)i=16+9i.

Answer: 16+9i

Tyina is buying 12 shirts for the drama club. She will choose a style for the blank shirts and then pay an additional charge of

tensa zangetsu [6.8K]

Answer:

Cost of each blank shirt is less than or equal to $ 5.5

Step-by-step explanation:

Let x denotes cost of each blank shirt.

Total number fo shirts bought by Tyina = 12

Amount charged for each shirt to have the club logo = $2.75

So,

Amount charged for 12 shirts to have the club logo = $12(2.75)=\$33$

As Tyina cannot spend more than $99,

$12x+33\leq 99$

Now solve the inequality.

$12x+33\leq 99\\12x\leq 99-33\\12x\leq 66\\x\leq \frac{66}{12}\\ x\leq 5.5$

So,

Cost of each blank shirt is less than or equal to $ 5.5

Find the surface area of the composite figure

Gnoma [55]

Answer:

$=280$ $in^2$

Step-by-step explanation:

----------------------------------------

Let's find the surface area of the pink rectangular prism first.

$2*10=20+20=40$

$4*10=40+40=80$

$4*2=8+8=16$

$40+80+16=136$

The surface area for the pink rectangular prism is $136$ $in^2$ .

-------------------->>>>>

Now, let's find the surface area of the green rectangular prism.

$4*7=28+28=56$

$4*7=28+28=56$

$4*4=16+16=32$

$56+56+32=144$

The surface area for the green rectangular prism is 144 $in^2$ .

-------------------->>>>>

Now let's add the surface area of both rectangular prisms to find the surface area of the composite figure.

$136+144=$

$=280$ $in^2$

----------------------------------------

Hope this is helpful.
