Answer:

An parabola has focus at( -43/4, 4) and directrix x = -13/4.

The vertex is exactly between focus and directrix, then:

=> vertex ([(-43/4 + (-13/4)]/2, 4) = (-28/4, 4) = (-7, 4)

The directrix x = -13/4 is a vertical line, this parabola is thus a sideways parabola (that looks left or right, not upward or download). It has the equation form as following:

4p(x – h) = (y – k)^2

with vertex(h, k) and p is distance from vertex to directrix

p = |-7 - (-13/4)| = |-15/4| = 15/4.

However, the vertex (-7, 4) is on the left of directrix x =-13/4, then this parabola faces left. Therefore p should be -15/4, not 15/4

=>4*(-15/4)*(x - (-7)) = (y - 4)^2

=>Solution: -15(x + 7) = (y - 4)^2

Hope this helps!

Find the measure for angle f 46 34 122 58

xxMikexx [17]

Answer:

$\angle f = 122\degree$

Step-by-step explanation:

$\angle d = 58\degree$ (vertical angles)

$\angle f+\angle d= 180\degree$

(Interior angles on the same side of transversal)

$\angle f+ 58\degree = 180\degree$

$\angle f = 180\degree-58\degree$

$\huge \orange {\boxed {\angle f = 122\degree}}$

Write and evaluate the expression. Then, select the correct answer. The sum of forty-five and a number; evaluate when n = 1. 1 4

Colt1911 [192]

The sum of forty-five and a number n is 46.1, and the expression that can represent this can be written "45+n" where the value of n is 1.1

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The statement that is given to us is" the sum of forty-five and a number", therefore, the expression that will represent this can be written as,

45 + n,

Now, if the value of n is 1.1. Then the sum will be,

$45+n\\\\=45+1.1\\\\=46.1$

Hence, the sum of forty-five and a number n is 46.1, and the expression that can represent this can be written "45+n" where the value of n is 1.1

Question: Image Below

konstantin123 [22]

Answer:

The answer will be: C: 2t + 10

Step-by-step explanation:

You can check the answer by replacing t with any number.

Example:

I want to find the perimeter for 3 triangles. Here's how I would write the equation.

2(3) + 10 = 6 + 10 = 16

We can check by adding all the sides for three triangles.

2 + 2 + 2 + 5 + 5 = 16

Hope this helped :)
