Answer:

a. h = 60t − 4.9t²

b. 12.2 seconds

c. 183.7 meters

Step-by-step explanation:

a. Given:

y₀ = 0 m

v₀ = 60 m/s

a = -9.8 m/s²

y = y₀ + v₀ t + ½ at²

h = 0 m + (60 m/s) t + ½ (-9.8 m/s²) t²

h = 60t − 4.9t²

b. When the ball lands, h = 0.

0 = 60t − 4.9t²

0 = t (60 − 4.9t)

t = 0 or 12.2

The ball lands after 12.2 seconds.

c. The maximum height is at the vertex of the parabola.

t = -b / (2a)

t = -60 / (2 × -4.9)

t = 6.1 seconds

Alternatively, the maximum height is reached at half the time it takes to land.

t = 12.2 / 2

t = 6.1 seconds

After 6.1 seconds, the height reached is:

h = 60 (6.1) − 4.9 (6.1)²

h = 183.7 meters

[tex]6x^{2}[/tex] ([tex]x^{2}[/tex]) + [tex]6x^{2}[/tex] ([tex]4x[/tex]) + [tex]6x^2[/tex] (-12)

[tex]6x^{2}[/tex]([tex]x^{2}[/tex] + [tex]4x[/tex]) +  [tex]6x^{2}[/tex] (-12)

Answer:

True! All triangle angles must add up to 180 degrees, thus an angle greater than 90 degrees would only give the rest of the angles 90 degrees to work with, which would make them acute.

Answer:

15$

Step-by-step explanation:

Step 1: First determine the value of the whole amount, which is 50.

Step 2: Determine the percentage, which is 30.

Step 3: Convert the percentage 30% to its decimal form by dividing 30 into 100 to get the decimal number 0.3:

30/100 = 0.3

(Dividing into 100 is the same as moving the decimal point two places to the left.)

30.0 → 3.00 → 0.30

Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount:

0.3 x 50 = 15 (answer).

Hope this helps.

The answer to the problem is $35

Finding the percentage of a number 'n', we have to multiply it by the percentage to be found divided by 100, so for example, 20% of n is equal to 0.2n.

The discount percentage is the amount that we do not have to pay and hence we subtract the percentage of the discount while paying.

The discount percentage is 30%

The total price is $50, hence 30% of 50 is 0.3*50=15

So there is a discount of $15, hence the cost of a chair after the discount will be 50-15 = 35

Hence, Mary's father bought the chair for the price of 35$

Answer:

y = [tex]\frac{1}{2}[/tex] x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (4, 0)

m = [tex]\frac{0+1}{4-2}[/tex] = [tex]\frac{1}{2}[/tex] , thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 0 ), then

0 = 2 + c ⇒ c = 0 - 2 = - 2

y = [tex]\frac{1}{2}[/tex] x - 2 ← equation of line

Answer:

I think it's cot(135°)

Step-by-step explanation:

Cot 135° = Cot (π/2 + 45)

and,

Cot (π/2+45)= -tan (45),

because when a trigonometric ratio is impressed by using π/2 the ratio should be changed its opposite like sin value turns into a cos value, tan value turns into cot and vise versa. Then as 135° is in the second sector that means π/2<135°<π. So it should be -tan(45°)

As tan-45°= -tan 45° i think the answer is second one aka cot(135°)

The equivalent expression of tan(-45) is cot(135)

The given trigonometric expression is: tan(-45).

To do this, we make use of the following trigonometry ratio

[tex]\cot (\frac{\pi}{2}+\theta)= -\tan (\theta)[/tex]

Substitute 45 for [tex]\theta[/tex].

So, we have:

[tex]\cot (\frac{\pi}{2}+45)= -\tan (45)[/tex]

In trigonometry, [tex]\frac{\pi}{2} = 90[/tex].

So, we have:

[tex]\cot (90+45)= -\tan (45)[/tex]

Add 90 and 45

[tex]\cot (135)= -\tan (45)[/tex]

Also, we have:

[tex]\tan (-45)= -\tan (45)[/tex]

So, the equation becomes

[tex]\cot (135)= \tan (-45)[/tex]

Rewrite as:

[tex]\tan (-45) = \cot (135)[/tex]

Hence, the equivalent expression of tan(-45) is cot(135)

Answer:

I believe it is C or D.  (C) The IQR is the best measurement of spread for games and movies.

(D) The standard deviation is the best measurement of spread for games and movies.

The explanation why it could be D:

Measures of spread are stats that describes how separated are the group of data between each other.

The measures are range, quartiles, variance and standard deviation. Among these measures, the standard deviation is the one that best expresses the variation, dispersion or spread of a set of values, because is based on the difference between each data and the mean, it takes in count each separation.

The explanation why it could be C:

Our both box plots are highly skewed, therefore, the IQR is the best measurement of spread for games and movies and option C is the correct choice.

I believe it is C, my friend. So I would go with C.

The best modeled by a discrete graph is body temperature of an athlete during a workout.

The correct option is (D)

A discrete graph is one with scattered points. They may or may not show a direction or trend. They don't  have data in between the points already given.

A continuous graph has a line because there is data in between the points already given.

So, according to the condition the best modeled discrete graph is body temperature of an athlete during a workout.

This is because for the body temperature measure, we only need to measure it once in a while.
