We have,
A polynomial with the highest power of 2 is called a quadratic equation.
A quadratic function whose zeroes are -7 and -3.
This means the quadratic function has zeroes.
x = -7
x + 7 = 0 ____(1)
x = -3
x + 3 = 0 _____(2)
Let the quadratic function be f(x) = y.
From (1) and (2) we get,
y = (x + 7)(x + 3)
y = x² + 3x + 7x + 21
y = x² + 10x + 21
Thus,
The quadratic function whose zeroes are -7 and -3 is
y = x² + 10x + 21

Please help me to solve the question.
Answer: A = (-2, 0) B = (-1, 1) x² + y² = 1/2
Step-by-step explanation:
To find where the line and circle intersect, create a system of equations and use the Substitution method to find the coordinates:
EQ1: x - y + 2 = 0 → x = y - 2
EQ2: x² + 2x + y² = 0 → (y - 2)² + 2(y - 2) + y² = 0
→ (y² - 4y + 4) + (2y - 4) + y² = 0
→ 2y² - 2y = 0
→ 2y(y - 1) = 0
→ 2y = 0 y - 1 = 0
y = 0 y = 1
Plug the y-values into EQ1 to solve for x:
x = y - 2 x = y - 2
x = 0 - 2 x = 1 - 2
x = - 2 x = - 1
Coordinates: (-2, 0) & (-1, 1)

Diameter of AB: d² = (x₂ - x₁)² + (y₂ - y₁)²
= [-2 - (-1)]² + [0 - (-1)]²
= (-2 + 1)² + (0 + 1)²
= (-1)² + 1²
= 1 + 1
d² = 2
d = √2
→ r = √2/2
Equation of a circle is: (x - h)² + (y - k)² = r²
Since a center was not provided for the equation with diameter AB, you can choose any value for center (h, k). I choose to let (h, k) = (0, 0) (x - 0)² + (y - 0)² = (√2/2)²
x² + y² = 2/4
x² + y² = 1/2

determine the domain of the following graph
Answer:x is greater than or equal to -7 but less than 9.
Step-by-step explanation:
Find the lowest and higest points on the graph.
Remember the domain is on the x - axis.
The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.
The next step is that the graph is getting larger so it is greater than or equal to.
On the other side of the graph do the same but it is less than not equal because the dot is open.
Step-by-step explanation:
2. Darrell applied for a $5,200 loan from his credit union to purchase new office furniture. The simple annual interest rate on the loan is 5%. How much interest will Darrell save if he obtains the loan for 2 years instead of 2 1/2 years?
Answer: $130
Step-by-step explanation:
Simple interest is calculated as:
= PRT/100
where P = principal = $5200
R = Rate = 5%
T = Time = 2 years
S.I = (PRT)/100
= (5200 × 5 × 2)/100
= 52000/100
= $520
Assuming the loan was obtained for 2 1/2 years, the simple Interest will be:
= (5200 × 5 × 2.5)/100
= 65000/100
= $650
This means he'll have saved:
= $650 - $520
= $130

Two dices are tossed. What is probability that you will see even numbers on both dices? Answer should be in reduced
fraction format
Answer:
3/6
Step-by-step explanation:
Well 3 is half of 6 and if you were to turn that into a fraction it would either be 3/6 or 1/2.
The probability that you will see even numbers on both dice will be 0.25.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
Two dice are tossed. Then the total number of events will be
Total events = 6 × 6
Total events = 36
The probability that you will see even numbers on both dice will be
The number of the favorable event will be given as,
Favorable events = 9
Then the probability is given as,
P = 9 / 36
P = 1/4
P = 0.25
The probability that you will see even numbers on both dice will be 0.25.

1 and 2 are vertical angles. If m_1 =
(6x + 11) and m2 = (10x - 9), find m1.
Answer:
x=5
Step-by-step explanation:
You have to put them together 6x+11=10x-9 then you can either subtract 6x or 10x. It would be easier to subtract 6x from 10x. 11=4x-9, then you would add 9 to both sides, finally you divide that answer by 4. That would be the answer to x.

The area of
this triangle
is 180 ft?,
what does x
have to be?
Answer:
x has to be 6
Step-by-step explanation:
Let us revise the rule of the area of a triangle
→ The area of any triangle = [tex]\frac{1}{2}[/tex] × base × height
In the given triangle:
∵ The triangle is a right triangle
∵ Its base = 5x ft
∵ Its height = 12 ft
∵ Its area = 180 ft²
→ Substitute these values in the rule of the area above
∴ 180 = [tex]\frac{1}{2}[/tex] × 5x × 12
→ Simplify the right side
∵ [tex]\frac{1}{2}[/tex] × 5x × 12 = 30x
∴ 180 = 30x
→ Divide both sides by 30 to find x
∴ [tex]\frac{180}{30}=\frac{30x}{30}[/tex]
∴ 6 = x
∴ x has to be 6
To check your answer find the area of the triangle
∵ Its base = 5x = 5(6) = 30 ft
∵ Its height = 12 ft
∴ Its area = [tex]\frac{1}{2}[/tex] × 30 × 12 180 ft²
∴ The value of x is correct.
A die is rolled and a coin is tossed.
Find the probability that an odd number is followed by either a head or a tail?
Answer: The probability of an odd number is 1/2, and the probability of a tail is also 1/2, so the probability of both occurring is the product, 1/4.
Step-by-step explanation: The coin is fair, the probabilities of getting a head and a tail are equal to 12 . The probability of getting an even number on a die is 36=12 because among 6 results there are 3 even numbers
Answer:
There are three outcomes in which tails occur with an even number (2, tails), (4, tails), (6, tails). The probability of this event is 3 / 12 = 1 / 4. The probability that tails and an even number do not occur together is. 1 - 1 / 4 = 3.4

Answer: Four more than zero, four greater then zero, positive four.
Step-by-step explanation: hope this helps
Answer:
Four more than zeroFour greater than zeroPositive fourStep-by-step explanation:
The original statement is "four above zero". Four above zero is 4.
Negative four, would be -4. That is the opposite of the original answer. Therefore, they're not equal.Four more than zero is 0 + 4. 0 + 4 is 4, which is the answer to the original statement. Therefore, they're equal.Four greater than zero is represented like this: 0 + 4. 0 + 4 = 4, so they are equal.The opposite of positive four is negative four, so it is not correct.Four less than zero is this: 0 - 4. 0 - 4 is equal to -4, so they are not equal.Positive four is pretty self-explanatory. It's 4. So, that is correct and equal to the original statement.I hope this helps!

Two planes leave San Antonio at the same time.
The northbound planc travels 70 mih faster than
the southbound plane. The planes are 1940 mi
upart in 2 h. How fast is the southbound plane
flying?
Answer:
Speed of the southbound plane = 450 mph
Step-by-step explanation:
Let the speed of the northbound plane = x miles per hour
And the speed of the southbound plane = y mph
Since, northbound plane travels 70 mph faster than the southbound plane,
x = y + 70 -----(1)
The planes are 1940 miles apart in 2 hours.
From the formula,
Distance traveled = Speed × time
Distance traveled by northbound plane in 2 hours = 2x miles
Distance traveled by the southbound plane in 2 hours = 2y miles
2x + 2y = 1940
x + y = 970 -----(2)
By substituting the value of x in equation (2) from equation (1)
y + 70 + y = 970
2y = 970 - 70
y = 450 mph
from equation (2)
x + 450 = 970
x = 520 mph
