Answer:
The vertex of this parabola is [tex](-2,-11)[/tex]
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation [tex]-\frac{b}{2a}[/tex]
From the function [tex]f(x)=x^2+4x-7[/tex], we can see that
[tex]a=1\\b=4\\c=-7[/tex]
This means that
[tex]-\frac{b}{2a}=-\frac{4}{2(1)} =-2[/tex]
So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.
[tex]f(x)=x^2+4x-7\\\\f(-2)=(-2)^2+4(-2)-7\\\\f(-2)= 4-8-7\\\\f(-2)=-11[/tex]
Thus, the vertex of this parabola is [tex](-2,-11)[/tex]

Determine which regions contain cube roots of 8i. Check all that apply.
on real axis
on imaginary axis
quadrant 1
quadrant 2
quadrant 3
quadrant 4
Answer:
this is the right answer
The cube roots of 8i are in the region of on imaginary axis, quadrant 1, and quadrant 2 options 2, 3, and 4 are correct.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have a complex number:
= ∛8i
The cube roots of 8i are
The cube roots of 0+8i are:
1. √3 + 1i
2. -√3+1i
3. 0-2i
The complex number can be represented as:
= a + ib
a, and b are real numbers.
i is the iota.
Thus, the cube roots of 8i are in the region of on imaginary axis, quadrant 1, and quadrant 2 options 2, 3, and 4 are correct.

You can buy 8 apples at the Quick Market for $1.45. You can buy 6 of the same apples at Stop and Save for $1.22. Which place is the better buy?
The Quick Market will be the place for better buy than Stop and Save.
Comparison of rates for better buy: Find the rate of one unit. Compare the rates to decide the better buy.Given in the question,
Total amount paid for 8 apples at The Quick Market = $1.45 Total amount paid for 6 apples at Stop and Save = $1.22Rate of apples at The Quick Market = [tex]\frac{\text{Total amount paid}}{\text{Number of apples}}[/tex]
= [tex]\frac{1.45}{8}[/tex]
= $0.18125
≈ $0.18 per apple
Rate of apples at Stop and Save = [tex]\frac{1.22}{6}[/tex]
= $0.20333
≈ $0.20 per apple
Since, $0.18 is less than $0.22, The Quick Market will be the place for better buy than Stop and Save.

Pls can someone help me factorise: 4u²‐u-3
Answer:
(u - 1)(4u + 3)
Step-by-step explanation:
Given
4u² - u - 3
Consider the factors of the product of the coefficient of the u² term and the constant term which sum to give the coefficient of the u- term.
product = 4 × - 3 = - 12 and sum = - 1
The factors are - 4 and + 3
Use these factors to split the u- term
4u² - 4u + 3u - 3 ( factor the first/second and third/fourth terms )
= 4u(u - 1) + 3(u - 1) ← factor out (u - 1) from each term
= (u - 1)(4u + 3)
Thus
4u² - u - 3 = (u - 1)(4u + 3) ← in factored form

Answer:
The answer would be about 220 cards on the fourth year.
Step-by-step explanation:
We know the first year he collect 305,178,298.We add those and then subtarct from 1000.Since they are asking about you need to round each one.305->300 178->180 298->300 Now that you got your answer from those (780) subtract that from 1000.You should get 220.

A.64
B.128
C.192
D. Impossible to tell
Answer:
(B). 128°
Step-by-step explanation:
m∠5 = m∠2 + m∠4 = 64°
Because ∠2 ≅ ∠3 and ∠4 ≅ ∠1 , then m∠1 + m∠2 + m∠3 + m∠4 = 2 × 64 = 128°

Let f(x)=1/2x-3. Suppose you subtract 6 from the input of f to create a new function g, and then multiply the input of function g by 4 to create a function h. What equation represents h?
The equation for h is h(x)=?
PLZZZZ!! I NEED HELP ASAP!!!!
Answer: h(x)=2x-6
hope this helped
The value of h(x)= 2x- 36.
What is function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
f(x)=1/2x-3
Now, subtract 6 from the input of f to create a new function g
g(x)= 1/2x-3 -6
g(x)= 1/2x -9
and, multiply the input of function g by 4
h(x)= 4( 1/2x -9)
h(x) = 2x- 36
Hence, the value of h(x)= 2x- 36.

0.8-3.2x<-2-2.8x please help me answer this!!!!! it is timed
Answer:
x > 7
Step-by-step explanation:
0.8 - 3.2x < -2 - 2.8x
Add 2.8x to both sides.
0.8 - 0.4x < -2
Subtract 0.8 from both sides.
-0.4x < -2.8
Divide both sides by -0.4. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality symbol changes direction.
