- 8.5а - 4.5+ За = - 24.5​

Answer:

h= -20

t = -0.104 and -2.39s

Step-by-step explanation:

A juggler tosses a ball into the air. The balls height, h, and the t seconds can be represented by the equation h(t)=16t^2+40t+4. Suppose the juggler missed and the ball hit the ground. Find the maximum height of the ball and the time it took the ball to reach the ground. Round all answers to the nearest hundredth

The velocity of the body at its maximum height is zero

V= dh/dt

dh/dt = 32t + 40

0 = 32t+40

-32t = 40

t = 40/-32

t = -1.25s

Substitute t = -1.25 into the expression

h(t)=16t^2+40t+4.

h(-1.25)=16(-1.25)^2+40(-1.25)t+4.

h = 16(1.5625)-50+5

h = 25-45

h =-20

Hence the maximums height is -20m

The ball will reach the ground at h = 0

Substitute

h(t)=16t^2+40t+4.

0 = 16t^2+40t+4

Divide through by 4

0 = 4t²+10t+1

Factorize

-10±√10²-4(4)/2(4)

t = -10±√100-16/8

t = -10±√84/8

t =-10+9.17/8

t = -0.83/8 and -19.17/8

t = -0.104 and -2.39s

Answer:

-2g - 11

Step-by-step explanation:

Expand the brackets, multiply 2 over 3g and -4. One plus and one minus make a minus.

2(3g-4) - (8g+3) = 6g - 8 - 8g - 3

Evaluate like terms.

6g - 8 - 8g - 3 = -2g - 11

3/4 of a bag of dog food will last for 2.25 days.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If 3 bags of dog food are used every day, then in one day, 1 bag of dog food will last:

1 day = 1/3 bag of dog food

To find how many days 3/4 of a bag of dog food will last, we can divide 3/4 by 1/3:

(3/4) ÷ (1/3)

= (3/4) × (3/1)

= 9/4

= 2.25

Therefore,

3/4 of a bag of dog food will last for 2.25 days.

Answer:

[tex]6[/tex], [tex]8[/tex] and [tex]10[/tex]

Step-by-step explanation:

Let [tex]x =[/tex] smallest consecutive even integer.

Since the second and third consecutive even integers can be expressed by our smallest even consecutive integer, we can express them as:

Second consecutive even integer = [tex]x+2[/tex]

Third consecutive even integer = [tex]x+4[/tex]

From "the sum of the second and third is 3 times the first integer", we can write:

[tex]x+2+x+4 = 3x[/tex]

[tex]2x+6 = 3x[/tex] (collect like-terms)

[tex]x=6[/tex]

∴ The first consecutive even integer is 6

Now, we can use substitution to find the values of the second and third consecutive even integers:

Second consecutive integer = [tex]x+2[/tex]

[tex]=6+2[/tex]

[tex]=8[/tex]

Third consecutive integer = [tex]x+4[/tex]

[tex]=6+4[/tex]

[tex]=10[/tex]

∴ The three consecutive even integers are [tex]6[/tex], [tex]8[/tex] and [tex]10[/tex].

Answer:

x=3.333 or 10/3

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*x-(2*(-6*x+18)+14)=0

Pull out like factors :

  -6x + 18  =   -6 • (x - 3)

to make 3x -  (-12 • (x - 3) +  14)  = 0

Pull out like factors :

15x - 50  =   5 • (3x - 10)  to get

5 • (3x - 10)  = 0

Solve  :    3x-10 = 0

Add  10  to both sides of the equation :

                     3x = 10

Divide both sides of the equation by 3:

                    x = 10/3 = 3.333

Answer:

f

Step-by-step explanation:

substitue the y

3x=2(-6x+18)+14

distrubute

3x=-12x+36+14

combine like terms

3x=-12x+50

add -12x on both sides

15x=50

divide 15 on both sides

x=50/15

simplify

x=10/3

Answer:

  y = 14x + 10

Step-by-step explanation:

We are given two points, (x, y) = {(5, 80), (3, 52)}. The 2-point form of the equation for a line can be used to find the equation.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (52 -80)/(3 -5)(x -5) +80 . . . . . fill in the given values

  y = (-28/-2)(x -5) +80 . . . . . simplify a bit

  y = 14x -70 +80 . . . . . eliminate parentheses; next, collect terms

  y = 14x +10

Step-by-step explanation:

Given that:

Total yards of satin bought by Maddie = [tex]3\frac{2}{3}[/tex] yards

Number of yards required make one ribbon = [tex]\frac{2}{3}[/tex] yards

To find:

Number of complete bows that can be made ?

Solution:

First of all, let us learn about converting the mixed fraction to fractional form.

Formula:

[tex]a\dfrac{b}{c} = \dfrac{a\times c+b}{c}[/tex]

Therefore, total yards of satin bought by Maddie can be written in fractional form as:

[tex]3\dfrac{2}{3} = \dfrac{3\times 3+2}{3} = \dfrac{11}{3}[/tex]

One hair bow requires [tex]\frac{2}{3}[/tex] yards of ribbon.

Number of hair bows that can be made, can be found by dividing the total ribbon length by ribbon required for making one hair bow.

Answer is:

[tex]\dfrac{\frac{11}{3}}{\frac{2}{3}}\\\Rightarrow \dfrac{11\times 3}{2\times 3}\\\approx 4[/tex]

4 hair bows can be made.

Answer:

|x - 2| = 15 ; |x + 2| = 15

Step-by-step explanation:

Given that:

Wait time = 15 minutes

Variation in wait time depending on level of hotness = 2 minutes

X ± 2 = 15

x + 2 = 15 or x - 2 = 15

x = 15 - 2 = 13 or x = 15 + 2 = 17

Hence, to express the above as an absolute value equation :

|x - variation| = mean time

|x - 2| = 15 ; |x + 2| = 15
