Find the equation of the quadratic function with vertex (– 2, – 6) that goes through the point (-4, -18)
Answer:
y = -3(x+2)^2 - 6
Step-by-step explanation:
y = a(x+2)^2 -6
-18 = a(-2)^2 - 6
-12 = 4a
a = -3
y = -3(x+2)^2 - 6

Find the length of h. Round to the nearest hundreth.
Answer:
h = 0.24
Step-by-step explanation:
Assuming this is a parallelogram...
Sine trig ratio
[tex]\sin(\theta)=\sf \dfrac{O}{H}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuseLet x be the angle in the top left of the parallelogram.
[tex]\implies \sin(x)=\dfrac{0.3}{0.5}=\dfrac35[/tex]
Opposite angles in a parallelogram are congruent.
Therefore, the angle in the bottom right of the parallelogram is also x.
[tex]\implies \sin(x)=\dfrac{h}{0.4}[/tex]
[tex]\textsf{As} \:\sin(x)=\dfrac35[/tex]
[tex]\implies \dfrac35=\dfrac{h}{0.4}[/tex]
[tex]\implies h=\dfrac35 \cdot 0.4=0.24[/tex]
Remember (3,4,5) Pythagorean triplet
Triangle containing y
Hypotenuse=0.5Base=0.4Triangle containing x
Base=0.4Perpendicular=0.3Now use ratio to find
0.5/0.3=0.4/h5/3=0.4/h5h=1.2h=1.2/5h=0.24Prove

Step-by-step explanation:
1 1/3 for one recipe.
2/3 cups for the second recipe.
1 2/3 for the third recipe.
Add all of the amount of cups used to get the total amount of sugar used.
1 1/3 + 2/3 + 1 2/3 = 3 2/3
She used 3 2/3 cups of sugar in all.
hope this helps!! p.s. i really need brainliest :)
can someone answer this is that I do not understand and I need it.
Answer:
y = 110 degree
x = 70 degree
z = 70 degree
Step-by-step explanation:
Vertical angles are always congruent.
so, the angle with the 110 degree is equal to the angle y.
now we have the measure of y.
as you can see angle y and angle z form a straight light wich means the sum of angle y and angle x is 180 degree
now, to get the measure of angle z,
180 - 110 = angle z
70 = angle z
now we have the measure of angle z
as angle z and angle x are vertical angle, they are congruent.
so angle x = 70
x = 70
z= 70
y = 110
hope this helps:)

Answer:
5 million.
Step-by-step explanation:
1 hundred thousand = 100,000
50 of these = 5,000,000 (replacing the 1 in 100,000 by 50)
and this = 5 million.

Alejandro will deposit $1,750 in an account that earns 6.5% simple interest every year. His sister Anallency will deposit $1,675 in an account that earns 7.5% interest compounded annually. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Which sibling will have more money at the end of four years?
Answer: Anallency
Step-by-step explanation:
First, lets make two equations for both siblings, using the base: SI = P(1 + rt) and CI = P(1 + r/n)^nt
Alejandro = 1750(1 + 0.065[4]) = 1750 + 455 = $2,205
Anallency = 1675(1 + 0.075/1)^4 = $2236.91
After 4 years, Alejandro will have $2,205, and Anallency will have $2236.91
Since $2236.91 > 2,205, Anallency will have more money after 4 years.
Answer:
Anallency will have mor money.
Step-by-step explanation:
Simple Interest:
I = Prt
I = $1750 × 0.065 × 4
I = $455
Total after 4 years: $1750 + $455 = $2205
Compound Interest:
F = P(1 + r/n)^(nt)
F = $1675(1 + 0.075)^(4)
F = $2236.91
Answer: Anallency will have mor money.

Answer:
196 - 49[tex]\pi[/tex]
i hope this helped :)
Step-by-step explanation:
first of all the explaination is to first find the area of the square and then the circle after you have found that you should subtract them and you will get the area of the shaded region.
radius x 2 = the side of the square
7 x 2 = 14
area of square - 14 x 14 = 196 squared
formula of finding the area of the circle - [tex]\pi[/tex]r^2
area of circle - 3.14 x 7 x 7 = 49[tex]\pi[/tex]
so answer simpliefied is 196 - 49[tex]\pi[/tex]
i hope this helped

Answer:
Step-by-step explanation:
This quadratic equation is given in standard form, which is [tex]y= ax^2 +bx+c[/tex]. The x-value of the vertex of a quadratic equation can be found using the given formula. Therefore, we can plug the the numbers given into the formula as such: [tex]x=\frac{24}{2(6)}[/tex]. This can be simplified into 2. Now that we have the x-coordinate, we can plug that back into the equation to find the y-coordinate: [tex]y=6(2)^2-24(2)+30[/tex]. This simplifies to y = 6. Therefore, the vertex of the equation is located at (2,6).

Which expression represents "eight less
than twice a number"?
Answer:
2n-8
Step-by-step explanation:
The expression eight less then twice a number will be shown in the following steps.
First, we tackle the first part of the sentence “Eight less” from here we can derive that there is a -8 in the expression.
Secondly, we can tackle the second part “twice a number” so this would be mean 2 times N, or 2n
From the two steps previously we can the conclude the answer must be 2n-8

How does the graph of f(x) = (x − 1)2 relate to the basic function f(x) = x2?
Answer:
Shift 1 unit to the right
Step-by-step explanation:
Note: Both functions can not be represented by f(x) and square is missing in basic function.
The given basic function is
The given function is
So, the given function can be written in the form of basic form as
...(1)
The translation is defined as
.... (2)
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
On comparing (1) and (2), we get
Therefore, graph of f(x) shift 1 unit to the right to get graph of g(x).
Answer: b.) shift 1 unit to the right

Given circle E with diameter CD and radius EA. AB is tangent to E at A. if AD = 15 and EC = 14, solve for AC.
Answer:
AC ≈ 23.6 units
Step-by-step explanation:
m∠CAD = 90°
CD = 2×14 = 28 , AD = 15
CD² = AD² + AC² ⇒ AC² = CD² - AD²
AC² = 28² - 15² = ( 28 - 15 )( 28 + 15 ) = 13 × 43 = 559
AC ≈ 23.6
-1.6, 5/2, -7/8, 0.9, -6/5 from least to greatest
Answer:
starting with least...
-1.6
-6/5
-7/8
9/10
5/2
...to greatest.
Step-by-step explanation:
start by putting the decimals into fractions:
-1.6 = -8/5
0.9 = 9/10
and then find a common denominator to compare them fairly.
the number that they all end up going into is 40, which will be your common demoninator.
-8/5 (aka -1.6) = -64/40
5/2 = 100/40
-7/8 = -35/40
9/10 (aka 0.9) = 36/40
-6/5 = -48/40
