Answer:

Step-by-step explanation:

With no middle term, we factor the quadratic into two binomials of the form (x+a)(x-a) where a is the same number. 64 factors only into 8(8) where the factors are equal. We write in the form (x+8)(x-8).

To find the root or x-intercept, we set equal to 0.

(x+8)(x-8)=0

x=-8,8.

Answer:

Option 4 is correct

x° + 126° = 180° and value of x is 54°

Step-by-step explanation:

Here, In a given Triangle two sides are equal i.e., Isosceles Triangle.

We know that, in a triangle the sum of all angles Is 180°.

If two sides are equal then also two angles are also equal of that sides.

Now,

63° + 63° + x° = 180°

x° + 126° = 180°

Now, To find the value of x

x° + 126° = 180°

x° = 180° - 126°

x = 54°

Thus, The value of x is 54°

<h3>FOR VERIFICATION ONLY:-</h3>

x° + 126° = 180°

54° + 126° = 180°

180° = 180°

Hence, L.H.S = R.H.S

Ainat [17]

Cost of aluminum required to make a ball of radius 7.5 inches is $ 161.71

<h3>Solution:</h3>

Given that

Goran's company makes solid balls out of scrap metal for various industrial uses.

For one project, he must make aluminum balls that have a radius of 7.5 inches.

Cost of aluminum = $0.12 per cubic inches

Need to determine cost of aluminum to make one ball.

Lets first calculate the volume of one ball

As shape of the ball is sphere , we can use volume of sphere formula

$\text {Volume of ball }=\text { Volume of sphere }=\frac{4}{3} \pi r^{3}$

Where "r" is the raius of ball

Given that radius of required ball = 7.5 inches

$\text { So, volume of ball of radius } 7.5 \text { inches }=\frac{4}{3} \pi \times 7.5^{3}$

$=\frac{4}{3} \times 3.14 \times 321.875=1347.5833 \text { cubic inches }$

So quantity of aluminum required is same as volume of ball = 1347.5833 cubic inches

Cost of aluminum for 1 cubic inch = $0.12

So cost of aluminum required to make a ball of aluminium of 1347.5833 cubic inches is given as:

$=0.12 \times 1347.5833=\$ 161.71$
