f(x)=-x^2-4x+12
find the minimum/maximum value
Answer:
Maximum Value / Vertex : (-2,16)
Step-by-step explanation:
Since the value of a is negative, we will solve for the maximum.
Finding the x-value of the vertex of the parabola is x=-b/2a:
x=-(-4)/2(-1)
x=4/-2
x=-2
Now if we plug x=-2 into the function, we'll get our y-value for the vertex:
f(-2)=-(-2)^2-4(-2)+12
f(-2)=-(4)+8+12
f(-2)=-4+20
f(-2)=16
So the vertex of our parabola is (-2,16) which is our maximum value
the average of three numbers is 1/5. Two of the numbers are 1/4 and 1/3. what is the third number?
Answer:
The third number is 1/60
Step-by-step explanation:
Let the denominator of the number = x
1/4 + 1/3 + 1/x = 1/5
1/4 + 1/3 = 3/12 + 4/12 = 7/12
The lowest common denominator is 60x.
(7/12 + 1/x)/3 = 1/5 Remember that this is the average of 3 numbers. That's what the 3 is doing on the left. Multiply both sides by 3
7/12 + 1/x = 3/5 Multiply through by 60x
35x + 60 = 36x
x = 60

(20 points) How many, and what type of solutions do the follow
quadratic equations have?
4x2 - x +4= 0
Answer:
2 , Real
Step-by-step explanation:
The quadratic equation is ,
⇒ 4x² - x - 4 = 0 .
Since it is a quadratic equation and has the highest degree of variable as 2 therefore it will have two solutions . For determining the nature of roots we will find the discriminant . The Discriminant of a quadratic equation in standard form of ax² + bx + c = 0 , is ,
⇒ D = b² - 4ac
⇒ D = (-1)² - 4 × 4 × (-4)
⇒ D = 1 + 64
⇒ D = 65 .
Since Discriminant is Greater than 0 , therefore the roots will be real .
The Barga school grows lettuce and other vegetables for school lunches. The school garden is 8.4 meters long and 6.4 meters wide. The section used to grow lettuce is 2.2 meters long and 0.8 meters wide. How many square meters of garden is not used to grow lettuce?

What is a rectangle?A rectangle is one of the types of quadrilaterals in which all four angles are right angles or equal to 90 degrees. It is four-sided polygon in which the opposite sides are parallel and equal to each other.
For the given situation,
The school garden is in the shape of the rectangle.
The school garden's length = 8.4 meters
The school garden's wide = 6.4 meters
The section used to grow lettuce, length = 2.2 meters
The section used to grow lettuce, width = 0.8 meters
Area of garden is not used to grow lettuce is
⇒ [tex][(8.4)(6.4)-(2.2)(0.8)][/tex]
⇒ [tex][53.76-1.76][/tex]
⇒ [tex]52[/tex]
Hence we can conclude that 52 square meters of garden is not used to grow lettuce.

The hypotenuse of a right triangle measures 17 cm. One leg of the triangle measures 15 cm. Find the length of the other leg of the triangle
Need Help?
Answer:
8cm
Step-by-step explanation:
The length of the other leg can be determined using the Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
17² = 15² + b²
289 = 225 + b²
b² = 289 - 225
b² = 64
b = √64
b = 8cm

A rectangle has vertices at (0,0), (3,0), and (0,6). What is the area
of the rectangle?
I’ll mark you!
Answer:
18 square units
Step-by-step explanation:
The area of a rectangle is simply it's base length multiplied by its height.
A = b × h
Since a rectangle has all right angles, it must have two sets of parallel sides.
Given the coordinates (0, 0), (3, 0), (0, 6) which are vertices of the rectangle. You can find the distance between each point to get the side length and then multiply the two side lengths together.

Applying the angles of intersecting chords theorem, the measure of arc EI is: 140°.
What is the Angles of Intersecting Chords Theorem?Based on the angles of intersecting chords theorem, the measure of the vertical angle formed when two chords intersect equals half the sum of the measures of the intercepted arcs.
Given the following:
m∠EXY = 80°m∠K = 25°m(EY) = m(YI)m∠K = 1/2(2(EY) -m(JL))
25 = 1/2(2(m(EY)) -m(JL))
50 = 2(m(EY)) -m(JL)
m(JL) = 2(m(EY)) - 50
m∠EXY = 1/2(m(JL) + m(EY) [angles of intersecting chords theorem]
Substitute
80 = 1/2[2(m(EY)) - 50 + m(EY)]
2(80) = 2(m(EY)) - 50 + m(EY)
160 = 3(m(EY)) - 50
160 + 50 = 3(m(EY))
210 = 3(m(EY))
210/3 = m(EY)
m(EY) = 70°
m(EI) = 2(m(EY)) = 2(70)
m(EI) = 140°
Therefore, applying the angles of intersecting chords theorem, the measure of arc EI is: 140°.

GEOMETRY Can anyone help for brainly, this is one of five questions, a (rotation, reflection, or translation) of 90° (clockwise, or counterclockwise,) about the origin followed by a (rotation, reflection, or translation) (right, left, up, down) _ Unit (s)
Answer:
See below-
Step-by-step explanation:
It depends on if you are transforming O to P or P to O
O to P would be rotate counterclockwise translate down 4
using the point (-3,2) from P and it's corresponding point from O (6,3)
rotate 90 counterclockwise (x,y)--> (-y,x) From point O - (6,3)--> (-3,6)
so after the rotation that point would be at (-3,6) to get the point to (-3, 2) move it down 4. so it is translated down 4
if you are transforming O to P is would be the opposite
rotate 90 clockwise and translate up 4

Write a verbal sentence for x -18 = 24
Example: I had money but won $116 and ended up with a total of $505.
Answer:
I had a great quantity of apples and used 18 to make a large apple pie for my family and I, then I only had 24 left over.
Step-by-step explanation:
X in the equation represents the amount of apples I have at the beginning of the apple pie making process. Minus 18 represents the apples that are being used for the apple pie, so they are not there anymore. 24 represents the apples left over.

ILL GIVE BRAINLEST, find the value of x.
Answer:
x⁰ = 45⁰
Step-by-step explanation:
As it is given that the 2 sides of a triangle are equal, then it is an isosceles triangle.
Now, by applying the Triangle Sum Property,
x⁰ + 90⁰ + 45⁰ = 180⁰
x⁰ = 180⁰ - 135⁰
x⁰ = 45⁰
Hope it helps :)
Answer:
x = 45 degrees
Step-by-step explanation:
A triangle is always 180 degrees. One angle is already labeled 45 degrees, and we can tell this is a right triangle, so the other angle is 90 degrees. Add 45 + 90 to get 135. Then subtract 135 from 180 to get 45, which is the value of the missing angle.

A company sells each product they make for $78.00. They pay $2,700.00 in monthly costs, such as rent and bills, as well as $65.00 in manufacturing costs per unit. If the company sold 626 units last month, what was their total profit?
A. $46,063.00
B. $5,438.00
C. $37,990.00
D. $7,065.60
Answer:
B. 5438
Step-by-step explanation:
[(78-65)×626]-2700=5438
The correct option is, (B) 5438
Definition of profit:
In general, profit is defined as the amount generated from the sale of a product, which should be greater than the product's cost price. It is the amount gained from any business activity. In other words, if a product's selling price (SP) is more than its cost price (CP), it is deemed a gain or profit. It refers to the financial gain obtained when the revenue from a company activity exceeds the costs of running the business, such as taxes and expenses.
Profit formula:Profit is better expressed in terms of cost and sale price. The cost price of a product or commodity is the price at which it is purchased, whereas the selling price is the price at which it is sold. If the selling price of the commodity is more than the cost price, the company has made a profit. Profit or Gain = Selling Price – Cost Price is the formula for calculating profit.
However, when a product is sold for less than its cost price, it is referred to as a loss. As a result, loss equals cost price minus selling price.
According, to the question:
A business makes 78.00 per unit and pays 2,700.00 in monthly charges, such as rent and bills, plus 65.00 in manufacturing costs each unit. If the firm sold 626 units in the previous month.
[(78-65)×626]-2700
= 5438
Hence, The company's overall profit is 5438.

Two small planes start from the same point and fly in opposite directions. The first plane is flying 25 mph slower than the second plane. In 2 hrs, the planes are 470 mi apart. Find the rate of each plane.
Answer:
105 mph = rate of first plane
130 mph = rate of second plane
Step-by-step explanation:
Let r = rate of first plane
then r + 25 = rate of second plane
2r = distance of first plane
2(r + 25) = distance of second plane
2r + 2(r + 25) = 470
2r + 2r + 50 = 470
4r = 420
r = 105 mph
r + 25 = 130 mph
