Answer:
[tex](x,y) =(-4,-3)[/tex] --- Vertex
[tex]x = -4[/tex] --- Axis of symmetry
Step-by-step explanation:
Given
[tex]y = -6(x + 4)^2 - 3[/tex]
Solving (a): The vertex
For an equation written in
[tex]y = a(x - h)^2 + k[/tex]
The vertex is:
[tex](x,y) = (h,k)[/tex]
By comparison:
[tex]y = a(x - h)^2 + k[/tex] and [tex]y = -6(x + 4)^2 - 3[/tex]
[tex]-h =4[/tex] [tex]k = -3[/tex]
[tex]h =-4[/tex] [tex]k = -3[/tex]
So, the vertex is:
[tex](x,y) =(-4,-3)[/tex]
Solving (b): The axis of symmetry
For an equation written in
[tex]y = a(x - h)^2 + k[/tex]
The axis of symmetry is:
x = h
In (a):
[tex]h =-4[/tex]
So:
[tex]x = -4[/tex]

7 Romeo and Juliet first saw each other when they were 270 feet apart.
Romeo began running toward Juliet at a rate of 16 ft/s. At the same
moment, Juliet began running toward Romeo at a rate of 14 ft/s.
A. How many seconds after they started running will they meet?
B. How far will Romeo have run then?
Answer:
A: 9 seconds
B: 144 ft.
Step-by-step explanation:
A:
Let t = no. of seconds for them to meet
When they meet the sum of their distances is 270 ft, dist = rate * time
16t + 14t = 270
30t = 270
t = 270/30
t = 9 seconds
B:
He ran 9 sec at 16 ft/sec, therefore:
9 * 16 = 144 ft

Solve for x. 5000(2)^x = 3500(3)^x
Answer:
0.887966
Step-by-step explanation:
1. Divide by 3500
(5000/3500)(2^x) = (3^x)
2. divide by 2^x and simplify
10/7 = (3/2)^x.
3. apply 'ln' function
ln(10/7) = xln(3/2)
4. divide ln(3/2)
ln(10/7) / ln(3/2) = x
x = 0.87966

The number of subsets in a set of n elements is given by: [tex]2^{n}[/tex]
In this question:
3 dishes.
[tex]2^{3} = 8[/tex]
only one, two of them, or all three of the dishes.
Considering the dishes, there are no empty set(there cannot be an order with no dishes), so 8 - 1 = 7
Ishaan could make 7 possible combinations of meals.
The design for a small counter top
is shown. What is the perimeter and
area of the counter top?
Answer:
P = 22 ft
A = 18 ft²
See picture
Step-by-step explanation:
The perimeter is all the sides added together. You have to find the missing values. The missing vertical value is 2.5 (4-1.5). The missing horizontal value is 4 (7-3).
Add all the sides together for the perimeter.

Simplify to a single power of 2: 2^4/ 2^3
Step-by-step explanation:
This leads to another rule for exponents—the Power Rule for Exponents. To simplify a power of a power, you multiply the exponents, keeping the base the same. For example, (23)5 = 215. For any positive number x and integers a and b: (xa)b= xa· b.

Bean seeds from supplier A have 85% germination rate and those from supplier B have 75% germination rate. A seed-packing company purchases 40% of its seed from A, 60% from B, and mix them together. Find the probability that a seed selected at random from the mixed will germinate.
Answer:
0.79 = 79% probability that a seed selected at random from the mixed will germinate.
Step-by-step explanation:
Probability of a seed germinating:
85% of 40%(from company A)
75% of 60%(from company B)
Then
[tex]P = 0.85*0.4 + 0.75*0.6 = 0.79[/tex]
0.79 = 79% probability that a seed selected at random from the mixed will germinate.

ABC measures 140° and is bisected
by BD. What is mDBC= ?
Answer:
angle abc =140°
and bd bisected by bd so, bd divede angle abc.
angle dbc= angle abc / 2
angle dbc=140°/2
angle dbc=70°
The measure of angle DBC from the given figure is 70°.
The measure of angle ABC is 140°.
What is an angle bisector?The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.
Angle bisector BD is bisecting angle ABC equally, which is
∠ABC=∠ABD+∠DBC
⇒ 140°=∠DBC+∠DBC
⇒ 2∠DBC=140°
⇒ ∠DBC=70°
Therefore, the measure of angle DBC from the given figure is 70°.

4. Combine the two equations to eliminate one of the variables, and then solve for the other. (3 points: 1 for eliminating one variable, 1 for the answer, and 1 for showing your work)
Answer:
Step-by-step explanation:
The solution of the system is:
(x, y) = ( 5, 10)
We have the following system of equations:
12x + 6y = 120
4x + y = 30
Now, We have to solve by the method of elimination, we multiply the second equation by -3, then:
12x + 6y = 120___(1)
-12x - 3y = -90___(2)
Now, We add both the equations:
12x -12x + 6y - 3y = 120 -90
3y = 30
y = 10
We have to find the value of 'x":
4x + y = 340x + 10 = 30
4x = 30 - 10
x = 5
Thus, the solution of the system is:
(x, y) = ( 5, 10)
