Answer:

multiply length times width.

Step-by-step explanation:

The given expression is :

To simplify the expression for x :

Add 5 on both side :

Divide the expression by 4 on both side :

Thus : x ≥ 3

The graph is :

Since x is greater than or equal to 3

So, it is closed on 3

Answer :

The graph has a closed circle on 3 and is shaded to the right of the origin

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

frequency histogram

Step 02:

discrete math:

sum of two dice:

we must analyze the graph to find the solution.

most frequent outcome:

frequency = 20

least frequent outcome:

value of dice = 2

frequency ≅ 2

how many times (7):

15 times (frequency)

percentage of times (7):

percentage (7) = (15 / 100) * 100%

percentage (7) = 15%

The description of the motion of the ball, which is a projectile are as follows;

(a) The window coordinates are; (0, 138.49)

(b) The x–component is 7.22 m)s

The y–component is -3.22 m/s

(c) The equations for displacement are;

(d) 16.07 m from the base

(e) Height of the ball location before it was thrown is 138.49 meters

(f) Time to reach 10.0 m. is 1.14 s

Projectile motion is the motion of an object that is thrown or thrusted into the air such that the major force acting on an object is the force of gravity

(a) The parameters of the motion of the ball are;

Initial velocity of the ball = 7.8 m/s

Direction to which the ball is tossed = 24° below the horizontal

Time it takes the ball to strike the ground = 5.00 s

Location of the origin of the coordinates = The base of the building

[tex]h = v_{iy} \cdot t + 0.5 \cdot g \cdot t²[/tex]

Where;

h = The height of the window

[tex]u_{y}[/tex]

The initial vertical velocity = 7.8×sin(24°) ≈ 3.173 m/s

g = The acceleration due to gravity ≈ 9.81 m/s²

t = The time duration of the motion = 5.00 s

Therefore;

h = 3.173×5 + 0.5×9.81×5²≈ 138.49

The height of the window, h ≈ 138.49 meters

Given that the window shares the same x–coordinates with the base, which is 0, we have;

(b) The x and y–component of the initial velocity are therefore;

v = 7.9 m/s × (cos(24°)•i - sin(24°)•j)

v = 7.22•i - 3.21•j

The x and y component of the velocity are therefore

x–component [tex] v_{ix} [/tex] = 7.22•i

y–component, [tex] v_{y} [/tex] = -3.21•j

Therefore;

(c) The equation of the x–component of the position is found as follows;

x = 7.9×cos(24°) × t = 7.22 •t

y = 7.9×sin(24°) × t+ 0.5× 9.81×t²

(d) The distance from the base of the building where the ball lands is given by the equation

d ≈ 3.21 × 5 ≈ 16.07

(e) The height from which the ball was thrown, h, is given by the y–coordinate in option (a) therefore;

(f) When the distance traveled = 10 meters, we have;

[tex]h = v_{iy} \cdot t + 0.5 \cdot g \cdot t²[/tex]

Which gives;

10 = 3.21•t + 0.5×9.81×t²

Solving with a graphing calculator, gives;

t ≈ -1.79 or t = 1.14

The possible value for the time it takes to reach the point 10 meters is therefore;

The value of x in the given right triangle is 8√5.

Pythagoras theorem states the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

The length of side z of the triangle is calculated as follows;

z² = y² + 4²

The length of side x is calculated as follows;

x² + z² = (16 + 4)²

x² + z² =  20²

substitute the value of z² into the equation,

x²  + y² + 4² = 20²

x²  + y² = 20² - 4²

x²  + y² = 384

Considering the second triangle, with sides, 16, x and y, the value of side y is calculated as follows;

y² = x² - 16²

y² = x² - 256

x²  + y² = 384

x²  + x² - 256 = 384

2x² = 384 + 256

2x² = 640

x² = 640/2

Let the intial height of the zucchini plant be g₀

g₀ = 10 cm

Size of growth per day = 0.5 cm

Let the growth after x days be represented by g(x)

a) The rule that represents the function is therefore:

g(x) = g₀ + 0.5x

g(x) = 10 + 0.5x

b) After how many days will the Zucchini pant be 0.185 meters tall

That is g(x) = 0.185 meters

since 1 meter = 100 cm

g(x) = 0.185 x 100 cm

g(x) = 18.5 cm

Thereofre substitute g(x) = 18.5 into the equation g(x) = 10 + 0.5x

18.5 = 10 + 0.5x

18.5 - 10 = 0.5x

0.5x = 8.5

x = 8.5 / 0.5

x = 17

The zucchini plant will be 0.185 meters tall after 17 days

The savings plan balance (future value) after 3 years with a 7% APR and monthly payments of $100 is $3,993.01.

The future value is the present value or cash flows compounded at an interest rate for a period.

The future value can be computed using an online finance calculator.

N (# of periods) = 36 months

I/Y (Interest per year) = 7%

PV (Present Value) = $0

PMT (Periodic Payment) = $100

Results:

FV = $3,993.01

Sum of all periodic payments = $3,600 ($100 x 36)

By using a trigonometric identity, we will see that the value of sin(x/2) is:sin(x/2) =  ±√39/√56 = ± 0.834

Here we need to use the identity: (sin(x/2))^2 = (1 - cos(x))/2

So, we know that:

cos(x) = -11/28

Then:

(1 - cos(x)) = 1 + 11/28 = 28/28 + 11/28 = 39/28

Replacing the identity that we get:

(sin(x/2))^2 = (1 - cos(x))/2 ]= (39/28)/2 = (39/56)

Now we can apply the square root in both sides, so we will get:

sin(x/2) = ±√(39/56)=  ±√39/√56 = ± 0.834

So, the value of sin(x/2) can be either 0.834 or -0.834.
