If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?
laiz [17]

Answer:

12 students

Step-by-step explanation:

Here is the complete question

Alex surveyed 60 students about their favorite zoo animals and made the circle graph of the results shown below. A circle graph titled Favorite Zoo Animals is shown. There are five sections. One section is labeled Bears, one section is labled Lions, one section is labeled Monkeys, one section is labeled Elephants, and one section is labeled Giraffes.

If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?

Number of students that said the giraffe was their favorite zoo animal = (angle measuring the section for giraffes / sum of angles in a circle graph) x number of students surveyed

the sum of angles in a circle = 360 degrees

(72 / 360) x 60 = 12 students

Write a quadratic equation whose factors are 4+3i and 4-3i.
inna [77]

Answer:

y=x^2-8x+25

Step-by-step explanation:

To answer this question, we will work backwards.

We know that a factor is 4+3i. This means that:

(x-(4+3i))=0

Hence, we will eliminate the imaginary and convert this into standard form.

First, distribute the negative:

x-4-3i=0

Add 3i to both sides:

x-4=3i

Square both sides:

(x-4)^2=(3i)^2

Expand:

x^2-8x+16=9(-1)=-9

Add 9 to both sides:

x^2-8x+25=0

Hence, our quadratic equation is:

y=x^2-8x+25

Notes:

We will get the same equation if we use (4-3i). This is because we square the (3i) regardless of its sign, making it positive.
