Answer:

Step-by-step explanation:

We can find the time it takes the object to reach its max height

At the Max height dh/dx = 0

dh/dx = -32x + 48

Since dh/dx = 0

0 = -32x + 48

32x = 48

x = 48/32\

x = 1.5secs

Hence it takes the object 1.5secs to reach its max height

Answer:

Slope is -2/9 and y intercept is (0,2)

Step-by-step explanation:

Answer:

slope: - [tex]\frac{2}{9}[/tex]    y intercept: 2

Step-by-step explanation:

you need to rearrange the equation into a y=mx+b formation

m is always the slope b is always the y intercept

the new equation of would be

y=-[tex]\frac{2}{9}[/tex] x+2

Answer:

$7.20

Step-by-step explanation:

8% as a decimal would be 0.08.

To find the sales tax, you would multiply 0.08(90)

0.08(90)=7.2

In dollars, that would be $7.20

Answer:

The weight as a product of two factors is 4(5 - n)

Step-by-step explanation:

Factoring

The expression 20 - 4n represents the new weight in ounces of a pack of fruit cups.

We can factor the binomial by finding the Greatest Common Factor of 20 and 4n.

Factoring out 4:

20 - 4n = 4(5 - n)

The weight as a product of two factors is 4(5 - n)

Answer:

x=-2 is correct answer

Step-by-step explanation:

x-10=-4*3

x=-12+10

x=-2

Answer:

Step-by-step explanation:

1/3(x-10)=-4

multiply 1/3 into the parenthesis:  1/3x - 10/3 = -4

1/3x = -4+10/3

1/3x = -48/12 + 40/12

1/3x = -2/3

x = -2/3 ÷ 1/3

x = -2/3 × 3

x = -2

Step-by-step explanation:

-12x+3y=24

-12x+-3y=24-3y

-12x=24-3y

-12x-24=3y

divide 3 to all

-4x-8=y

or -8-4x=y

Answer:

The value of x = 2

Step-by-step explanation:

Given the equation

[tex]12\left(x-2\right)+3x=\frac{1}{2}\left(x+6\right)+2[/tex]

so the equation becomes

[tex]12x-24+3x=\frac{1}{2}x+3+2[/tex]

simplifying

[tex]15x-24=\frac{1}{2}x+5[/tex]

[tex]15x=\frac{1}{2}x+29[/tex]

multiplying both sides by 2

[tex]30x = x + 58[/tex]

subtracting x from both sides

[tex]30x - x = 58 - x[/tex]

[tex]29x = 58[/tex]

divide both sides by 29

[tex]\frac{29x}{29}=\frac{58}{29}[/tex]

simplifying

[tex]x = 2[/tex]

Therefore, the value of x = 2

Step-by-step explanation:

Step 1: Define

7x - 3 = 39

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 39 does indeed equal 39.

∴ x = 6 is the solution to the equation.

Answer:

5

Step-by-step explanation:

The degree of a polynomial is determined by the term with the largest exponent, the value of the exponent being the degree of the polynomial.

Given

5[tex]x^{?}[/tex] + y³ + y² + 8

For the polynomial to be of degree 5 , then

the exponent of the x- term must be 5

Step-by-step explanation:

Answer: There are 90 calories in a 6-ounce bottle.

Step-by-step explanation:

We assume that the quantity of juice in the bottle is directly proportional to the number of calories it contains.

Given: 10 ounces of juice has 150 calories.

i.e. 1 ounce of juice has [tex]\dfrac{150}{10}[/tex] calories.

i.e. 1 ounce of juice has 15 calories.

Now, In 6 ounce of juice, the number if calories = 15 x 6 = 90 calories

Hence, there are 90 calories in a 6-ounce bottle.

(10+10)÷(5-3)

Step-by-step explanation:

Always do the parentheses first.

20÷2

Then divide

10

(10+10÷5) -3 is wrong because you do 10÷5 first. That 2 and then +10 is 12. 12-3=9.

Answer:

c = 10

Step-by-step explanation:

Given that H varies directly as c³ then the equation relating them is

H = kc³ ← k is the constant of variation

To find k use the condition when H = 40, c = 2 , then

40 = k × 2³ = 8k ( divide both sides by 8 )

5 = k

H = 5c³ ← equation of variation

When H = 5 000, then

5000 = 5c³ ( divide both sides by 5 )

1000 = c³ ( take the cube root of both sides )

[tex]\sqrt[3]{1000}[/tex] = c , so

c = 10
