You could plug it into the equation since it is multiple choice or you could put it in your calculator and press 2nd and then graph. The answer should be the second one!
Hope this helps!

A steel company is making flat rectangular frames as a part of a new product they are launching. Each frame will be cut out of a

Luda [366]

The area of steel before cutting:

Area = $(11+2x)*(6+2x)$ cm²

= $4x^{2}+22x+12x+66$

Hence, Area= $4x^{2}+34x+66$

Area of steel after cutting out the 11*6 inside dimensions.

$4x^{2}+34x+66-(11*6)=4x^{2}+34x$

As the area should be close to 28 cm square, so equation becomes:

$4x^{2}+34x=28$ or $4x^{2}+34x-28=0$

Now for the answer, kindly see the image attached. It gives x=0.76

Hence, the answer is 0.76 cm.

Question 2 (Essay Worth 10 points)

Strike441 [17]

Answer:

(a) $f(2) = 81$

(b) $g(2) = 83$

Step-by-step explanation:

Given

$f(x) = 0.5x + 80$

$x \to g(x)$

$1 \to 81$

$2 \to 83$

$3 \to 85$

Solving (a): f(2)

We have:

$f(x) = 0.5x + 80$

$f(2) = 0.5*2+80$

$f(2) = 1 + 80$

$f(2) = 81$

Solving (b): g(2)

From the table:

$g(x) = 83$ when $x = 2$

So:

$g(2) = 83$

Solving (c): Which is greater f(2) or g(2)

In (a) and (b),

$f(2) = 81$

$g(2) = 83$

Hence, test average for maths class is greater
