Answer:

1.11 s , 10.88 m/s

Step-by-step explanation:

Initial velocity and air resistance = 0

Time to fall : s = 1/2 gt²

6 = 1/2 * 9.8 * t²

t² = 1.224

t = 1.11 s

final velocity = initial velocity + gt

                    = 0 + 9.8 * 1.11

                    = 10.88 m/s

Answer:

Step-by-step explanation:

Since no drop-downs are given, I'll guess and add the most suitable words for you.

The value of q is the y- intercept of y= ax^2 +q.

The q value moves the graph q units up or down and has (no option, could be shift) on the graph of the parabola.

The value of q causes a vertical shift of the parabola. The value of q causes a vertical shift of the graph.​

Answer:

a. Rosemarie has 16 grandchildren.

b. Each grandchild would receive $0.50 or 50 cents.

Step-by-step explanation:

a. There are 4 sons, and each son has 4 children.

Son 1: 4 children

Son 2: 4 children

Son 3: 4 children

Son 4: 4 children

So you can find the total number of grandchildren by adding up the amount of children each of the sons have: 4 + 4 + 4 + 4 = 16

Rosemarie has 16 grandchildren.

b. If the are $8 total, and it is split equally between Rosemarie's sons, it means each son would get $2 (because $8 / 4 sons = 2).

And then each son would split it between his 4 kids. So $2 / 4 kids = $0.50

Each grandchild would receive $0.50 or 50 cents.

Answer:

x = -2

Step-by-step explanation:

( 2x - 1 ) ( x + 3 ) - ( x + 3 ) ( x - 3 ) = x + 2

Expand

x^2 + 5x + 6 = x + 2

x^2 + 5x + 6 - 2 = x + 2 - 2

x^2 + 5x +4 = x

x^2 + 5x + 4 - x = x - x

x^2 + 5x + 4 = 0

-4 / 2 = -2

x = -2

the answer is 40

X 1 (+1) 2 (+1) 3 (+1) 4 (+1) 5

Y 4 (+9) 13 (+9) 22 (+9) 31 (+9) 40

Answer:

the missing value is 40 .

Step-by-step explanation:

if observed clearly the difference between every number is 9.

so 31+9 = 40 is the correct answer.

Answer:Solution for 0.3(y-2)+0.4y=0.3y-0.6 equation:

0.3(y-2)+0.4y=0.3y-0.6

We move all terms to the left:

0.3(y-2)+0.4y-(0.3y-0.6)=0

We add all the numbers together, and all the variables

0.4y+0.3(y-2)-(0.3y-0.6)=0

We multiply parentheses

0.4y+0.3y-(0.3y-0.6)-0.6=0

We get rid of parentheses

0.4y+0.3y-0.3y+0.6-0.6=0

We add all the numbers together, and all the variables

0.4y=0

y=0/0.4

y=0

Answer: 9^2 or can also be read as 9 squared.The base itself is worth 9 but when you include the exponent its 81.When your solving exponents your multiplying the base by itself as many times as the exponent reads.In this case its 9x9 (2 times). The value of the base is 9 (just wanted to explain the other stuff just in case you didn't know)

Answer:

(8-5)*(6+7+(8-6)+(7-5))

Step-by-step explanation:

By using the digits in a way of  (8-5)×(6+7+(8-6)+(7-5)) we get 51.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, we have to get a result of 51 using the digits  5, 6, 7, 8 and must use all of the numbers and only can use addition, subtraction, multiplication, or division this can be formed as,

51 = (8-5)×(6+7+(8-6)+(7-5))

Answer:

50%

Step-by-step explanation:

The distribution is symmetrical about  the y-axis.

The probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

The branch which deals with the occurrence of a random event is known as probability.

The area under the curve to the right of z = 0 is equal to the area under the curve to the left of z = 0. So the standard normal distribution is symmetric about the mean of zero

As the total area under the curve is equal to 1, each of these areas must be 0.5 or 50%.

In a standard normal distribution, the probability that z is greater than zero is 0.5, or 50%.

Therefore, the probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

Given info:

all sides are equal in the given triangle

Given angles are 3y° and 2x°

→ 3y° = 2x° = 60°

→ 3y° = 60° and 2x° = 60°

→ y° = 60°/3 and x° = 60°/2

→ y° = 20° and x° = 30°

Therefore, x° = 30° and y° = 20°

Answer:-

The values of x = 30° and y = 20°

Key Knowledge:-

→ If all sides are equal in a triangle then it is an equilateral triangle

In an equilateral triangle,

→ all sides are equal.

→ all angles are equal.

→ all angles are equal to 60°
