Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). The vertex of a parabola is (-2, -20), and its y-intercept is (0, -12).
The equation of the parabola is y = x2 + x + .
Step-by-step explanation:
-12 = a(0+2)²-20
-12=4a -20
4a = 20-12
4a=8
a=2
y = 2x²+ 8x -12
=> y = 2 x² + 8 x + -12
2 , 8 , -12
10) Planteen la operación y resuelvan: El producto entre el cuadrado de -7 y la raíz cubica de 1728, todo eso sumado 14.
Answer:
(-7)^2*∛(1728) + 14 = 49*12 + 14 = 588 + 14 = 602
Step-by-step explanation:
Primero definamos las operaciones usadas:
El cuadrado de un número N, se escribe como N^2
La raíz cubica de un número M, se escribe como ∛(M)
El producto entre dos números, A y B, se escribe como A*B
Ahora queremos plantear la operación:
"El producto entre el cuadrado de -7 y la raíz cubica de 1728, todo eso sumado 14."
Lo podemos separar en partes:
"El producto entre el cuadrado de -7 y la raíz cubica de 1728,..."
esto se escribe como:
(-7)^2*∛(1728)
Ahora, la operacion completa es:
El producto entre el cuadrado de -7 y la raíz cubica de 1728, todo eso sumado 14.
Esto se escribe como:
(-7)^2*∛(1728) + 14
Ahora debemos resolver esta operación.
sabemos que:
(-7)^2 = 49
∛(1728) = 12
Reemplazando esos dos en nuestra operación, obtenemos:
(-7)^2*∛(1728) + 14 = 49*12 + 14 = 588 + 14 = 602
Which is the smallest number which leaves remainder 8 and 12 when divided by 28 and 32 respectively?
Answer:
Which is the smallest number which leaves remainder 8 and 12 when divided by 28 and 32 respectively? 204.
Step-by-step explanation:
Have a great summer.
Answer:
204 is the smallest number.
Step-by-step explanation:
28 - 8 = 20 and 32 - 12 = 20
The required number will be 20 less than the LCM of 28 and 32.
Prime factorization of 28,
→ 2 × 2 × 7
Prime factorization of 32,
→ 2 × 2 × 2 × 2 × 2
LCM(28, 32) = 2 x 2 x 2 x 2 x 2 x 7 = 224
Hence, the required smallest number,
→ 224 - 20 = 204

What is the diameter of a hemisphere with a volume of 272\text{ m}^3,272 m
3 , to the nearest tenth of a meter?
Answer:
D = 10.1m
Step-by-step explanation:
We know that the volume of a sphere of radius R is:
V = (4/3)*pi*R^3
where pi = 3.14
A hemisphere is half a sphere, then the volume of an hemisphere is half of the volume of a sphere, then the volume of a hemisphere of radius R is:
V' = (1/2)*(4/3)*pi*R^3
Now, we know that our hemisphere has a volume:
V' = 272m^3
Then we can solve the equation:
272m^3 = (1/2)*(4/3)*pi*R^3
For R.
(we want the diameter, but remember that the diameter is equal to two times the radius, so finding the radius is a good start)
272m^3 = (1/2)*(4/3)*pi*R^3
272m^3 = (4/6)*3.14*R^3
272m^3*(6/4*3.14) = R^3
∛( 272m^3*(6/4*3.14) ) = R = 5.06 m
And the diameter is two times that, so we get:
D = 2*5.06m = 10.12 m
Rounding this to the nearest tenth of a meter (first digit after the decimal dot), we get:
D = 10.1m
Wrist bands are $1.25 each. Write a direct proportion equation to show the total cost (c) for any number of bands (b)
Answer:
[tex]c=1.25b[/tex]
Step-by-step explanation:
If we know that each band costs $1.25, then we know that 2 bands are $2.50, 3 bands are $3.75 etc. The equation above simply states that each band is $1.25, so $1.25 multiplied by the number of bands gives us a total cost. This follows the formula [tex]y=kx[/tex], for a direct proportion equation. Hope this helped :)
Help , what is the measure of p
Answer:
Step-by-step explanation:
let angle p be x
x+27=56 degree (sum of two opposite interior angle is equal to the exterior angle formed)
x=56-27
x=29 degree
therefore p is 29 degree.
the data from two random samples with 500 students were asked about their favorite Olympic sport is shown what percentage of students choose snowboarding as their favorite sport
A.10.5%
B.51%
C.25%
D.21%
Answer:
d: 21%
Step-by-step explanation:
1. add 180+135+105+80=500 total
2. then find the percent of 105 from 500 (Determine the total or whole amount.
Divide the number to be expressed as a percent by the total. In most cases, you'll divide the smaller number by the larger number.
Multiple the resulting value by 100.)
you get an answer of 21%
21% of students chose snowboarding as their favorite sport.

Tylers mom had a coupon for four dollars each of the train tickets.If they bought If they bought five train tickets and paid a total of $145, what was the original cost of each ticket?
Answer:
The original cost of each ticket will be = $33
Step-by-step explanation:
Number of coupons Tylers mom had = 5
The value of each coupon is = $4
Total value of coupons = 5 x 4 = $20
In order to find the original cost of the ticket, we just have to add the value of coupons to the amount paid for tickets.
The original cost of tickets = $145 + $20
The original cost of tickets = $165
Thus, the original cost of each ticket will be = 165 / 5
Thus, the original cost of each ticket will be = $33
there are 8 apples and 11 oranges in a bag. what is the ratio of the apples to oranges?
Answer:
8:11
Step-by-step explanation:
For every 8 apples, there are 11 oranges.
Answer:
8 : 11 = 8 : 11
Step-by-step explanation:
Divide both terms by the GCF, 1:
8 ÷ 1 = 8
11 ÷ 1 = 11
The ratio 8 : 11 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
8 : 11 = 8 : 11

Find area AND perimeter of the shape
Step-by-step explanation:
for the perimeter...
18-6=12
that's to get the slant side
perimeter=10+6+12+12+20
=60
for the area I'm not sure how to solve it sorry!!
Answer:
10 x 6 = 60
20 + 10 = 30, 30 x 12 x 1/2 = 180
180 + 60 = 240 cm2 is your area
6 + 6 = 12, 12 + 10 = 22, 22 + 20 = 42
Now lets find hypotenuse:
10 - 20 = 10, 10 divided by 2 = 5
5^2 + 12^2
25 + 144 = 169
Square root of 169 is 13
Add perimeters:
42 + 13 = 55 cm is your perimeter.
