Factor the tribunal into two binomials than solve?

Vanyuwa [196]

Answer:

$(x-5)(x-3)=0$

$x=5 \text{ and } x=3$

Step-by-step explanation:

Quadratic Equation given:

$x^2-8x+15=0$

In order to factor this equation think that we'll have something in the format: $(x-a)(x-b)$

Once: -a -b = -c

and (-a)(-b)= d

Therefore, we have

$(x-5)(x-3)=0$

$x-5=0\\\text{or}\\x-3=0$

$x=5 \text{ and } x=3$

You invest $50 in a government bond that says you can redeem it a year later for $54. Use the instructions in Lesson 3 to calcul

Afina-wow [57]

Invested amount in a government bond = $50.

Total returned amount after 1 year =$54.

We need to find the amount of interest earned first.

Amount of intrest earned in a year = Total returned amount after 1 year - Invested amount in the government bond.

Therefore, Amount of intrest earned in a year = $54 - $50.

= $4.

Therefore, earned interest is $4 in an year.

Now, we need to find the intrest rate.

We know the formula,

$Interest \ rate=\frac{Earned \ Interest}{Invested \ Money} \times 100$

Plugging values in above formula, we get

Rate of interest = $\frac{4}{50} \times100$

Dividing 100 by 50, we get 2.

$\frac{4}{50} \times100= 4\times2=8$

Therefore, Rate of Interest (ROI) = 8% per year.

1. A circular swimming pool has a diameter of 60 feet, and is surrounded by a concrete sidewalk that is 5 feet wide. What is the

Ivenika [448]

We first calculate the area of the entire pool and the side walk.

Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet

Thus the area of the entire pool and the side walk is obtained as follows:

$Area=\pi r^2 \\ \\ =\pi(35)^2=1,225\pi\ square\ feet$

Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.

Thus the area of the pool is given by:

$Area_{pool}=\pi r^2 \\ \\ =\pi(30)^2=900\pi\ square\ feet$

Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:

$Area_{side walk}=1,225\pi-900\pi \\ \\ =325\pi=1,021 \ square\ feet.$
