Complete the first 4 steps for graphing the quadratic function given. (Use ^ on the keyboard to indicate an exponent.) Then graph the quadratic function. Be sure to label the axes and vertex.
y = -x^2 - 4x - 3
( Thanks in advance!! )
The quadratic equation y = -x^2 - 4x - 3 has a degree of 2
The vertex of the function is (-2,1)
How to graph the function?The equation of the function is:
y = -x^2 - 4x - 3
Differentiate
y' = -2x - 4
Set to 0
-2x - 4 = 0
Solve for x
x = -2
Substitute -2 for x in y = -x^2 - 4x - 3
y = -(2)^2 - 4(-2) - 3
y = 1
The above means that the vertex of the function is (-2,1)

Step-by-step explanation:
i)
Consider the exponential equation
[tex]y = a {e}^{bt} [/tex]
Now Substitute these points to get a and b value
(0,37000) , (1,20350)
[tex]37000 = a \times {e}^{b \times 0} [/tex]
[tex]37000 = a \times 1[/tex]
Hence a=37000
Now Substitute t=1
[tex]20350 = 37000 \times {e}^{b \times 1} [/tex]
[tex] \frac{20350}{37000} = {e}^{b} [/tex]
[tex]0.55 = {e}^{b} [/tex]
[tex]b = log_{e}(0.55) = - 0.5978[/tex]
b≈(-0.6)
[tex]y = 37000 {e}^{ - 0.6t} [/tex]
is the required equation
ii)
[tex]y = 37000 {e}^{ - 0.6 \times 0.4} [/tex]
[tex]y = 37000 {e}^{ - 0.24} [/tex]
iii) it decreases by a factor of

((-6) + 7 - 3) x 2 divided by 4. Order of operations? I think the answer is -1.
Answer:
-1
Step-by-step explanation:
The order of operation (PEMDAS) states that:
P - ParenthesisE - ExponentsM - MultiplicationD - DivisionA - AdditionS - SubtractionGiven expression:
[{(-6) + 7 - 3} x 2] ÷ 4We can see that "-6" is the integer that is inside the parenthesis "( )". Therefore, we can open the parenthesis "( )".
⇒ [{-6 + 7 - 3} x 2] ÷ 4Simplify the expression inside the curvy brackets "{ }" using PEMDAS.
⇒ [{1 - 3} x 2] ÷ 4 [PEMDAS]⇒ [{-2} x 2] ÷ 4 [PEMDAS]Now we can open the curvy brackets "{ }".
⇒ [-2 x 2] ÷ 4Simplify the expression inside the long brackets "[ ]" using PEMDAS.
⇒ [-4] ÷ 4Finally, open the long brackets "[ ]" and simplify the expression obtained.

Once the apartment complex have been turned to a parking area, the total parking area will be 1620 square units
How to determine the total parking area?From the complete question, the parking area consists of the following shapes and dimensions
Rectangle: 28 units by 40 unitsRectangle: 20 units by 25 unitsThe area of a rectangle is the product of its dimensions.
So, the area of the parking area is:
Area = 28x40 + 20x25
Evaluate the products
Area = 1120 + 500
Evaluate the sum
Area = 1620
Hence, the total area of the parking area is 1620 square units

find the area of the shaded region. Use the formula A= pie r^2 to find the area of a circle
Answer:
(π6x+21π)m²
Step-by-step explanation:
Solution,
For small circle
radius(r)=x+2
Area(A1)=πr²
Area(A1)=π×(x+2)²
Area(A1)=π×(x²+4x+4)
Area(A1)=πx²+π4x+4π
For big circle
radius(r)=x+5
Area(A2)=πr²
Area(A2)=π×(x+5)²
Area(A2)=π×(x²+10x+25)
Area(A2)=πx²+π10x+25π
Again,
Area of shaded part=A2-A1
Area of shaded part=πx²+π10x+25π-(πx²+π4x+4π)
Area of shaded part=πx²+π10x+25π-πx²-π4x-4π
Area of shaded part=π6x+21π
Question
Find the surface area of the regular pyramid.
Answer:
Surface area:The sum of all the sides to a figure.Given that the area of the base is 440.4, all we would need to find out is the sum of all the areas of the triangles surrounding it.
Formula for area of a triangle:
A = BH x 1/2
Where 'B' represents the base, 'H' stands for the height, and 1/2 simply means to divide the product of those two lengths(base and height) by 2.
Plug in what we know:-
A = BH x 1/2
A = 16(20) x 1/2
A = 320 x 1/2
A = 320/2
A = 160 mm is the area of one triangle, but we want to know the area of all 5 triangles, so;
160(5)
= 800 mm is the area of all the triangles.
Now add the base area to the area of all the triangles.
440.4 + 800
= 1,240.4 mm.
Therefore the surface area of this pyramid is 1,240.4 mm.
Answer:
1240.4 mm²
Step-by-step explanation:
The surface area of a pyramid = Area of the all sides + Area of base
Each side is a triangle.
With a regular pentagonal pyramid, the area of each triangle is
A = 1/2 x base x slant height
For the 5 triangles,
A = 5 x 1/2 x base x slant height = 1/2 x 5 x slant height
Substitute values,
A = 5 x 1/2 x 16mm x 20mm = 800 mm²
Area of base = 440.4 mm²
Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²
Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°. Which of the following is a possible way to classify the triangle by side and angle measurements?
A. Obtuse and isosceles
B. Acute and scalene
C. Obtuse and equilateral
D. Acute and equilateral
Answer:
Acute and Scalene
Step-by-step explanation:
The measurments of the triangle are all almost equal and all the angles are less than 90 degrees, so all of them are acute angles. The scalene triangle has almost all equal sides.
The possible way to classify the triangle by side and angle measurements is,
⇒ Acute and scalene.
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°.
Since, All the angles are less than 90 degree.
Hence, It shows the Acute angle.
Here, Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm.
Clearly, All the sides of triangle are not same in length.
Thus, It shows scalene.
Thus, The possible way to classify the triangle by side and angle measurements is,
⇒ Acute and scalene.

There are 9 balls numbered 1 through 9 placed in a bucket. What is the probability of reaching into the bucket and randomly drawing four balls numbered 6, 9, 8, and 7 without replacement, in that order? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Using the permutation formula, as the order is important, it is found that there is a 0.000331 probability of selecting the balls in the desired order.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this problem, 4 balls will be taken from a set of 9, hence the total number of outcomes is:
[tex]P_{9,4} = \frac{9!}{5!} = 3024[/tex]
The desired outcome is only one, hence the probability is given by:
p = 1/3024 = 0.000331.
There is a 0.000331 probability of selecting the balls in the desired order.

• Pattern Q starts at 6 and follows the rule “subtract 2, multiply by 2" to get the
next term.

Pattern Q: 6, 8, 12, 20, 36

Pattern Q: 6, 8, 12, 20, 36
Answer:
pattern P: 8,13,23,43,83
pattern Q: 6,10,18,34,66
The tables that contain the first 5 elements of both patterns are:
Pattern P: 8, 13, 23, 43, 83Pattern Q: 6, 8, 12, 20, 36How to find the first 5 terms of each pattern?For pattern P we start at 8, and to get the next element we multiply by 2, and then subtract 3.
So the first 5 elements are:
[tex]a_1 = 8\\\\a_2 = 2*8 - 3 = 13\\\\a_3 = 2*13 - 3 = 23\\\\a_4 = 2*23 - 3 = 43\\\\a_5 = 2*43 - 3 = 83[/tex]
For pattern Q we start at 6, and then we subtract 2 and multiply by 2 to get the next element.
[tex]b_1 = 6\\\\b_2 = (6 - 2)*2 = 8\\\\b_3 = (8 - 2)*2 = 12\\\\b_4 = (12 - 2)*2 = 20\\\\b_5 = (20 - 2)*2 = 36\\\\[/tex]
