Select all of the statements that are true for the given parabola.
Answer:
A and B are true
Step-by-step explanation:
The minimum is the turning point on the graph and occurs at (1, - 2)
The x- intercepts are where the graph crosses the x- axis , that is at
x = - 1 and x = 3 or in coordinate form (- 1, 0 ) and (3, 0 )
The equation of the axis of symmetry is a vertical line passing through (1, - 2)
with equation x = 1
The true statements are A and B
Answer:
⇨ A and B choice
Step-by-step explanation:
⟺ Consider all choices.
⥱ Choice A is correct because It's upward Parabola ( a > 0) where there is only the minimum point/value. The minimum point is at (1,-2). The vertex for upward parabola can be called the minimum point.
⥱ Choice B is correct because the Parabola intercepts x-axis at (-1,0) and (3,0) from the graph.
⥱ Choice C is wrong because the Axis of Symmetry is supposed to be x-term/value for the Parabola. If it is the y-value/term then it would be Side Parabola.
⥱ Choice D is wrong because an upward Parabola doesn't have the maximum point. The only Parabola with maximum point is downward Parabola ( a < 0)

The percentages, from left to right, are:
1) 56.25%
2) 18.75%
3) 18.75%
4) 6.25%
How to get the percentages?In this case, the 100% is 16.
We know that there are 9 individuals with black fur and black eyes, so we can write the equations:
100% = 16
X% = 9
We want to find the percentage X%. By combining these equations we get:
X% = (9/16)*100% = 56.25%
Now we can use the same equations for the other genotypes.
There are 3 units with black fur and red eyes, here the percentage is:
p = (3/16)*100% = 18.75%
There are 3 units with white fur and black eyes, so the percentage is:
p = (3/16)*100% = 18.75%
There is 1 unit with white fur and red eyes, so the percentage is:
p = (1/16)*100% = 6.25%

What is the value of p?
I don’t know how to do this
Answer:
C.) 35
Step-by-step explanation:
Supplementary angles equal 180, therefore, the opposite side of both the angles 90 and 125, must be 180 minus that value.
180-125=55
180-90=90
Now we know that the two inside angles equal 55 and 90. Together, that's 145.
Since all the angles within a triangle equal 180, we subtract the two other angles to find p.
180-145=35
City Bank offers a 4.75% simple
interest rate, while First National
offers 3.9%. If Tom wants to set
up a new account with $500. how
much more money will he earn in
Interest at City Bank over First
National after 12 years?
Answer:
He will earn $51 more
Step-by-step explanation:
Let us compare the amounts he will earn in both banks
Mathematically, simple interest is;
I = PRT/100
Where P represents principal, R represents rate and T represents time
For Citibank, we have
I = (500 * 4.75 * 12)/100 = $285
For National bank
I = (500 * 3.9 * 12)/100 = 234
The difference between the amount of money earned in both banks will be;
285-234 = 51

Median of 40,2,31,15,29,16 and X is 21. then X= ?
Answer:
Let us arrange this data in ascending order.
2, 15, 16, 29, 31, 40.
x has to be in the middle if it is the median.
So it becomes 2, 15, 16, x, 29, 31, 40.
There are seven numbers. The median is the 4th one.
The median is given as 21.
So x = 21.

A drawing of a rectangular room has dimensions of 12 inches by 6 inches. If the scale is 2 inches : 4 feet, find the area of the actual room.
Answer: 288 feet
Step-by-step explanation:
Length of drawing = 12 inches
Actual length = 12 × (4/2)feet = 24 feet
Width if the drawing = 6 inches
Actual width = 6 × (4/2)feet = 12 feet
The area of the actual room will be gotten by multiplying the dimensions. This will be:
= 24 feet × 12 feet
= 288 feet
I’ll mark you brainlist I’ll mark you brainlist write in y=mx+b form I’ll mark you brainlist I’ll mark you brainlist
Answer:
y=5x+12
Step-by-step explanation:
Starting with the components of slope intercept form y=mx+b
m is you rate of change and b represents your y intercept
This would give you in your case y=5x+b, but we still need to solve for b.
So given your (x,y) point you plug it into y=5x+b giving you:
-3 = 5 (-3) + b
then some easy multiplication and addition
-3 = -15 + b
get the constant on the oppisite side of your variable b
-3 + 15 = -15 + 15 + b
This results in b = 12
Now rewrite the formula with b = 12
Which TADA! gives you
y = 5x + 12

Step-by-step explanation:
Your cell phone provider charges a monthly fee of $30. You are also charged $0.07 per minute
for each minute. Last month, Mr. Gonzales' bill was $59.40. Let m represent the total number
of minutes Mr. Gonzales used last month. Use the verbal model below to write an equation.
Answer:
0.07m + 30 = 59.40
Mr Gonzalez used 420 minutes last month
Step-by-step explanation:
To represent how much money Mr. Gonzales was charged for using minutes, use the term 0.07m.
Then, add 30 to this to represent the monthly fee:
0.07m + 30
Lastly, set this equal to 59.40 because that was his total bill for the month:
0.07m + 30 = 59.40
So, the equation for the situation is 0.07m + 30 = 59.40
Solve for m in the equation:
0.07m + 30 = 59.40
0.07m = 29.40
m = 420
So, Mr Gonzalez used 420 minutes last month.
Answer:59.40

Step-by-step explanation:
Answer:
3.643 × 10 ^− 1
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
3.643 × 10 ^− 1
there are four children in Jana's family. She is less than 11 years old and is the oldest. there's a two-years age difference to twins, riya and seta, who come next. yuvi who is older than 5 is 2 years younger than the twins. how old are each of the children?
Answer:
Jana=10, twins=8, yuvi=6
Step-by-step explanation:
it's the only possible answer,as we know yuvi is older than 5 so let's just say she is 6 then the twins are 2 years older=8 and we know that and is less then 11 so that would be 10
