Answer:

2 seconds

Step-by-step explanation:

[tex]y=-5t^2+20[/tex] (Given)

When acorn will hit the the ground, at that moment y = 0

[tex]\implies 0= -5t^2+20[/tex]

[tex]\implies 5t^2=20[/tex]

[tex]\implies t^2=\frac{20}{5}[/tex]

[tex]\implies t^2=4[/tex]

[tex]\implies t=\pm\sqrt4[/tex]

[tex]\implies t=\pm 2[/tex]

Time can not be negative.

[tex]\implies t\neq-2[/tex]

[tex]\implies t=2\:seconds[/tex]

Answer:

X= -10

Step-by-step explanation:

Answer:

Angle Relationship: Alternate exterior angles

x = -10

Angle measurement: 51 °

Step-by-step explanation:

These angles are located "outside" the two parallel lines but on opposite sides of the transversal, therefore they are alternate exterior angles.

Alternate exterior angles are congruent, therefore the angle must be 51 °

51 = 61 + x

subtract 61 from both sides

x = 10

Step-by-step explanation:

(ab + cd)² - (ac - bd)² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = ab + cd and b = ac - bd , then

= (ab + cd + ac - bd)(ab + cd - (ac - bd))

Hey there!

The first expression is

5x+15

The equivalent expressions are

5(x+3)

- the opposite of the Distributive Property: 5(x+3)=5x+15

Plus

isn't 5*x+5*3 the same as 5x+15?

Yeah, it is :)

Hence, the equivalent expressions are

[tex]\boxed{\boxed{\bold{Option\;A \;and\;Option\;B}}}[/tex]

[tex]\rule{200}{2}[/tex]

In order to simplify this expression, we need to combine like terms:

11+12y-3-y

The y's are like terms:

11+12y-y-3

11+11y-3

Can you spot any other like terms here? That's right, 11 and -3:

11-3+11y

8+11y

Hence, the equivalent expression is

[tex]\boxed{\boxed{\bold{11y+8}}}[/tex]

Hope everything is clear.

Let me know if you have any other questions; if so, please comment.

(b) Identify the slope and y-intercept of the equation.

Answers

The equation y = 3x - 5 is an illustration of a linear equation

The slope is 3, and the y-intercept is -5

How to complete the table?

The equation of the table is given as:

y = 3x - 5

When x = -1, we have:

y = 3(-1) - 5 = -8

When x = 0, we have:

y = 3(0) - 5 = -5

When x = 1, we have:

y = 3(1) - 5 = -2

So, the complete table is:

x     y

-1    -8

0      -5

1       -2

The slope and the y-intercept

A linear equation is represented as:

y = mx + b

Where:

m represents the slope and b represents the y-intercept.

By comparison, we have:

m = 3, and b = -5

Hence, the slope is 3, and the y-intercept is -5

In the addition problem below, the digits B and C represent a number different from any of the other numbers shown (that is, not 1, 4, 5, 6, or 9. B5+C9=164

Answers

B5 + C9 = 164

Split the numbers.

B0 +C0 +14 = 164.

B0 + C0 = 150

B + C = 15

B cannot be 1, 2, 3, 4, or 5 because that forces C to be a two digit number and C only represents 1 digit.

B cannot be 6 or 9 because they are present.

B can only be 7 or 8. C can also be 7 or 8.

Therefore, B = 7  and C = 8, OR B = 8 and C = 7.

first we have to distribuite

-16x^2+48x+64

then we have to look for a number that goes into all of these which is -16

x^2-3x-4

then multiply the first by the last

-4x^2

then we have to find a two number that adds to make -3 and multiples to make -4x2

What is a quadratic equation?

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

[tex]\rm \sqrt{x^2 + 81} = x + 10[/tex]

Squaring both sides, we have

[tex]\rm (\sqrt{x^2 + 81})^2 = (x + 10)^2\\\\x^2 \ \ +\ \ 81 \ \ = x^2 + 20x + 100[/tex]

Thus, the equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.
