Hey there! :D

We are basically trying to find fractions that equal each other.

3/12= 1/4 4/16= 1/4

The first option applies.

5/8= 5/8 (simplest form) 8/15= 8/15 (simplest form)

The second does not apply.

1/6= 1/6 (simplest form) 5/30= 1/6

The third option does apply.

18/12= 3/2 3/2=3/2 (simplest form)

The fourth option does apply.

The first, third, and fourth option are the answers.

I hope this helps!

A proportion is two or more parts, share or numbers that are considered comparative relation to a whole.

Basically, when you have two fractions, 2/4 and 3/6 for example, they will equal the same amount even if their numbers are different. Normally, we would reduce both of these fractions to 1/2 because 2 is 1/2 of 4 and 3 is 1/2 of 6.

With this information you should be able to figure out which choices are proportionate and which isn't. (hint** only one answer isn't proportionate)

If f(x) is defined as follows,

Phantasy [73]

Answer: The required values are

f(-2) = 120, f(0) = 64 and f(1) = 84.

Step-by-step explanation: We are given the following function f(x) :

$f(x)=16x^2+4x+64~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We are to find the values of the following :

$(a)~f(-2),\\\\(b)~f(0),\\\\(c)~f(1).$

To find the values of the function at the given points, we need to substitute the corresponding values of x in equation (i).

Substituting x = -2 in equation (i), we get

$f(-2)=16\times(-2)^2+4\times(-2)+64=64-8+64=120.$

Substituting x = 0 in equation (i), we get

$f(0)=16\times0^2+4\times0+64=0+0+64=64.$

Substituting x = 1 in equation (i), we get

$f(1)=16\times1^2+4\times1+64=16+4+64=84.$

Thus, the required values are

f(-2) = 120, f(0) = 64 and f(1) = 84.

In isosceles triangle △ABC,

Minchanka [31]

Answer:

Isosceles triangle:

* two sides are equal.

* the base angle are always equal and

* the altitude is a perpendicular distance from the vertex to the base.

Since, the triangle ABC is an isosceles and AC is the base

⇒ AB=BC and $\angle A = \angle C$

Also, AD is the angle bisector of $\angle A$ , which implies that it cuts the angle at A in two equal halves,

let $\angle A= x^{\circ}$ , then the bisectors cuts it in $(x/2)^{\circ}$ .

As per the given information, we know $\angle ADB$ is 110°, therefore, the line BDC forms a supplementary angle;

⇒ $\angle CDA = 180-110 =70^{\circ}$

As shown in picture given below:

By sum of all interior angles in a triangle is 180 degree, thus

$x+\frac{x}{2} +70^{\circ} =180^{\circ}$ or

$\frac{3x}{2} = 180-70 = 110^{\circ}$

Simplify:

$x=\frac{220}{3} = 73\frac{1}{3}^{\circ}$

Therefore, the $\angle A =\angle C = 73\frac{1}{3}^{\circ}$ .

Now, to find the angle B, we have;

$\angle A+ \angle B +\angle C = 180^{\circ}$ [Sum of the measure of the angles in a triangle is 180 degree]

$2\angle A+\angle B = 180^{\circ}$ or

$\angle B = 180^{\circ}- 2\cdot \frac{220}{3} =180^{\circ}-\frac{440}{3}$

Simplify:

$\angle B = \frac{100}{3}= 33 \frac{1}{3}^{\circ}$ .

Will give brainliest ! need help due in an hour

bekas [8.4K]

If I’m not mistaken your years are going to be the x value and the cases are your y values so type the year as the x value and type the number of cases as the y value Let me know if I was right
