Opens up or down, Vertex: (-10, -1), Passes through: (-8, -5)

Answers

Answer 1

Answer:

opens down

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) - (- 10, - 1 ) , then

y = a(x + 10)² - 1

To find a substitute (- 8, - 5) into the equation

- 5 = a(- 8 + 10)² - 1 ( add 1 to both sides )

- 4 = a(2)² = 4a ( divide both sides by 4 )

- 1 = a

y = - (x - 10)² - 1 ← equation in vertex form

To determine if it opens up/ down consider the value of a

• If a > 0 then curve opens up

• If a < 0 then curve opens down

Here a = - 1 < 0 then curve opens down

Jackson and his sister ran a hose from a bucket into their swimming pool. The hose sprays 1/3 of a gallon from the bucket every second. The bucket started with 32 gallons of water. How long will it take to empty the bucket?

Answers

96 seconds because if it shoots out 1/3 of a gallon per second we have to multiply that by 3. so it takes 3 seconds per gallon. so 3x32 is 96

Answer:

It will take 96 seconds to empty the bucket.

Step-by-step explanation:

To answer this all you have to do is divide 32 by 1/3. To do this you first have to turn 32 into and improper fraction by changing it into 31 3/3 and then multiplying 31 times 3 (93) and then adding 3, which gives you 96 so you get 96/3. You also have to change the division sign into a multiplication sign while also flipping 1/3 so its 3/1. Now you have to cross cancel and since the 3 in 96/3 can go into the 3 in 3/1 once, the 96/3 changes into 96/1 and the 3/1 changes into 1/1. Now you can multiply so 96 times 1 is 96 and 1 times 1 is 1 so you get 96/1 which is basically just 96 so your answer is that it will take 96 seconds to empty the bucket.

The sides of a triangle are in the ratio 10:6:24. The perimeter is 440 inches. What is the length of each side?

Answers

Answer:

one side = 110 inches

second side = 66 inches

third side = 264 inches

Step-by-step explanation:

10 + 6 + 24 = 40

one side of Δ = 10/40 x 440 = 110

second side of Δ = 6/40 x 440 = 66

third side of Δ = 24/40 x 440 = 264

The price of a refrigerator is Rs 66,400 after including GST at the rate of 17% . what is the amount of GST.

need totally explanation ​

Answers

Answer:

The amount of GST is Rs 9,647.87

Step-by-step explanation:

Given :

• The price of a refrigerator = Rs 66,400

• Price including GST

• Rate of GST = 17 %

To Find :

• The amount of GGS

Solution :

★ GST Amount = Original cost of the product or service - (Original cost of the product or service) x (100 ) / (100 + GST%)

⇒ 66,400 − (66,400) × (100) / (100 + 17)

⇒ [tex]\mathsf{66,400 - ( 66,400 \times \dfrac{100}{(100 + 17)} )}[/tex]

⇒ 9,647.87

GST Amount = Rs 9,647.87

∴ The amount of GST is Rs 9,647.87

tan²x + tan x - 12 = 0 (1)

suppose: tan x = t

(1)=> t² + t - 12 = 0

a = 1    b = 1     c = -12

⇒ Δ = b² - 4ac = 1 + 48 = 49 > 0 => has 2 solutions

=> t = [tex]\frac{1+\sqrt{49} }{2}=\frac{8}{2}=4[/tex]

or t = [tex]\frac{1-\sqrt{49} }{2}=\frac{-6}{2}= -3[/tex]

because t = tan x => tan x = 4 or tan x = -3

because x ∈ [0;2pi) => with tan x = 4 => x = arctan(4)  or x = arctan(4) + pi
