I WILL MARK BRAINLIEST! A parabola opening up or down has vertex (0,3) and passes through (4,7). Write its equation in vertex form.
Answers
Ok...so we have this........
y = ax2 + 4 ....... and we need to find "a"
So we have
-1 = a(-10)2 + 4
-5 = a (100)
(-1/20) = a ....... So we have ..........
y = (-1/20)(x- 0)2 + 4 or just (-1/20)x2 + 4
Note that this parabola opens downward...That makes sense since the vertex is above the x axis and the parabola passes through a point below the x axis.
Hope This Helped!

there are 5 people over 40 (43, 45, 50, 54, 58), which means the probability would be 5/15

Answer:
One equation you could use is 6(7 + 5) + 3.
Answer:
[tex]((3 * 7) - 6) * 5[/tex]
Step-by-step explanation:
For this problem, we will use trial and error.
It will take a while, but we can reduce the amount of guesses we have to make.
Looking at the problem, it is obvious that we will require multiplication at some point, as adding all the numbers together is nowhere near 75.
Let's start this problem by finding the prime factors of 75:
75 = [tex]25 * 3[/tex]
75 = [tex]5 * 5 * 3[/tex]
The prime factors of 75 are: [tex]5 * 5 * 3[/tex].
Our numbers are 7, 5, 6, and 3.
We already have a 5 and a 3, so we need to use 7 and 6 to get 5, and that's impossible, so this is a pass.
Next, we'll look at another factor, [tex]25 * 3[/tex].
We already have a 3, so we can ignore that. We need to use 7, 6, and 5 to get 25.
Here are some of the results:
[tex](5 * 6) - 7 = 23[/tex] (Nope)
[tex](7 * 5) - 6 = 29[/tex] (Nope)
[tex]6 + 5 + 7 = 18[/tex] (Nope)
There's more combinations, but the numbers are either too large or too small. This is a pass too.
Now, we'll try another factor, [tex]15 * 5[/tex].
We already have a 5, so let's ignore it and use 7, 6, and 3 to get 15.
[tex]7 + 6 + 3 = 16[/tex] (Nope)
[tex](6 * 3) - 7 = 11[/tex] (Nope)
[tex](3 * 7) - 6 = 15[/tex] (Yep)
So our expression to make 15 is [tex](3 * 7) - 6[/tex]. Then we multiply the whole thing by 5. Thus our expression is:
[tex]((3 * 7) - 6) * 5[/tex]
Let's check our answer:
[tex]((3 * 7) - 6) * 5[/tex]
[tex](21 - 6) * 5[/tex]
[tex]15 * 5[/tex]
[tex]75[/tex]
The expression gives us 75, which is what we want, so our answer is correct.
The $24.75 is the sale price after reducing the original price by 10%.
Calculate the original price
Answers
Answer: $ 27.50
Step-by-step explanation:
We know that $24.75 is (100%-10%) = 90% of the original price.
24.75/90 = 0.275 (to find one percent)
0.275 x 100 = 27.5 (100%, the original price)

The set of values are described below:
[tex]v = 25\,cm[/tex], [tex]w = 25^{\circ}[/tex], [tex]x = 25^{\circ}[/tex], [tex]y = 65^{\circ}[/tex] and [tex]z = 10\,cm[/tex].
Step-by-step explanation:
Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]OJ \parallel RS[/tex] and [tex]OP \parallel RM[/tex]. By Alternate Internal Angles, we find that [tex]\angle R \cong \angle O[/tex]. In addition, the sum of internal angles in triangles equals 180°. Then, we have the following system of linear equations:
[tex]m\angle R + m\angle M + m\angle S = 180^{\circ}[/tex] (1)
[tex]m \angle O + m \angle P + m\angle J = 180^{\circ}[/tex] (2)
[tex]m\angle S = 65^{\circ}[/tex] (3)
[tex]m \angle M = m\angle P = 90^{\circ}[/tex] (4)
The solution of this system is [tex]m\angle R = 25^{\circ}[/tex], [tex]m \angle O = 25^{\circ}[/tex] and [tex]m \angle J = 65^{\circ}[/tex].
Lastly, the remaining sides are found by definition of congruence
Segment RS
Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]\overline {RS} \cong \overline {OJ}[/tex]. Hence, [tex]RS = 25\,cm[/tex]
Segment JP
Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]\overline{SM} \cong \overline {JP}[/tex]. Hence, [tex]JP = 10\,cm[/tex]
The set of values are described below:
[tex]v = 25\,cm[/tex], [tex]w = 25^{\circ}[/tex], [tex]x = 25^{\circ}[/tex], [tex]y = 65^{\circ}[/tex] and [tex]z = 10\,cm[/tex].

arc HK = 50/360 * 2(3.14)(16)

A large box of crackers weighs 20 oz of james needs 3 pounds of crackers for a party how many boxes of crackers should he buy?
Answers
Answer:
James will need to buy 3 boxes of crackers for the party.
Step-by-step explanation:
remember: 16oz=1 pound
If James needs 3 pounds of crackers, and each box is 20oz, that means each box is a little over 1 pound. (1.25 pounds to be exact). So, we know that he needs to buy 3 boxes of crackers. This is because 20×3=60 ounces which is 3.75 pounds. Meaning, 3 boxes is the correct answer since we can't cut a box in half.
hope this helps!
Answer:
3 boxes
Step-by-step explanation:
First, calculate how many oz in one pound: 16 oz = 1 pound
Now we know that our situation includes smaller to larger.
Since we are going smaller to larger, we need to multiply.
You should multiply 20 x 3 = 60 oz from what I learned.
60 oz = 3.75 pounds. In another situation you would round, but who cares about rounding. Your answer is 99.100% correct
If this was wrong, I'm sorry. The way I learned is smaller to larger: multiply; larger to smaller: divide.
Hopefully, this was right!

Answers
Answer:
1 d know
Step-by-step explanation:
the correct use of the distance formula is the equation :
√((27 - 12)² + (y₂ - 15)²).
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given a diagram of a line for that distance, the line needs to find
the general formula for distance
d = √((x₂ - x₁)² + (y₂ - y₁)²)
Thus, for the given coordinates formula for distance
d = √((27 - 12)² + (y₂ - 15)²)
therefore, the equation √((27 - 12)² + (y₂ - 15)²) is the correct use of the distance formula.

there are two holes in the roof that are leaking water. the one in the bathroom drift 120 drops in an hour. the other one in the kitchen dripped 80 drops in 30 minutes. which one is leaking more water?
Answers
Answer:
the more leaking place is the bathroom
Explanation:
1 hour=60 minutes
the bathroom drift 120 drops in 60 minutes
so, the bathroom drift 1 drop in 120/60 minutes
=60 minutes
the other one in the kitchen dripped 80 drops in 30 minutes.
so, the other one in the kitchen dripped 1 drop in 80/30 minutes
= 8/3 minutes
so the more leaking place is the bathroom because 60 > 8/3
