Answer:

Time, t = 2.44 seconds

Step-by-step explanation:

Logan is doing a handstand dive from a 12 meter platform. The equation that models the path of her dive is given by :

[tex]h=-4.9t^2+12t[/tex]

It is required to find the time after which Logan will hit the ground. At this point, h = 0

[tex]-4.9t^2+12t=0\\\\t(-4.9t+12)=0\\\\t=\dfrac{12}{4.9}\\\\t=2.44\ s[/tex]

So, after 2.44 seconds it will hit the water.

Answer:

Option (4).

Step-by-step explanation:

Formula to calculate the volume of a cylinder is,

V = πr²h

Here r = radius of the cylinder

h = Height of the cylinder

From the figure attached,

r = [tex]\frac{13}{2}=6.5[/tex] cm

h = 11 cm

Now we substitute the values of h and r in the formula,

V = π(6.5)²(11)

   = 464.75π

   = 1459.32

   ≈ 1459.3 cm³

Therefore, volume of the given cylinder is 1459.3 cm³

Option (4) will be the answer.

Answer:

They are both correct

Step-by-step explanation:

tan A = opposite / adjacent = 3/4   >>> A= 36.9 deg

tan C = opposite / adjacent = 4/3   >>> C= 53.1 deg

cheak:

<B+ <A + <C = 180 deg

90 + 36.9 + 53.1 = 180

180 = 180

Answer:

Botn are correct

Step-by-step explanation:

Tan ratio can be obtained by opposite/adjacent

Both students are correct. They have different values only because they have taken different reference angles

Rhianna has taken angle A as the reference angle,

So tanA = opposite/adjacent = BC/AB

tanA = 3/4

Christopher has taken angle C as the reference angle,

So tanC = opposite/adjacent = AB/BC

tanC = 4/3

7/3

Step-by-step explanation:

To get the answer, we add all of the numerator numbers together since the denominators are all the same. 3 + 4 + 7 = 7 + 7 = 14

The answer is 14/6. We can then simplify it and divide both the numerator and the denominator by 2. That gives us 7/3 and that is our final answer.

Answer:

$44.8

Step-by-step explanation:

The tip:

35*0.2=$7

The total bill:

35*8% = 35*0.08 = 2.8

35 + 2.8 +7 = 44.8

(I added 35 for the price of the actual lunch, and the 7 for the tip)

Alternatively, you can just add the 8% and the 20% and the 100% (for the lunch itself), and then multiply the $35.

8%+20%+100%=0.08+0.2+1= 1.28

1.28*35=$44.8

Answer:

The base is 27 units long.

Step-by-step explanation:

This is a solve the system question. Call the length of the base B and the length of each leg L. We are told:

[tex]B=1.5L[/tex]

and

[tex]B+2L=63[/tex]

Sub the first equation into the second:

[tex]1.5L+2L=63\\3.5L=63\\L=18[/tex]

Now that we have the leg length, sub that into either of the original equations to find the base. I'll use the first equation:

[tex]B=1.5(18)\\B=27[/tex]

Answer:

60

Step-by-step explanation:

Answer:

(x)=(x-7)(x-4)

g(x)=x(2)+7x - 2

Now find a common denominator. (x+10)(x-4) is a good one.

x-16/(x+10)(x-4)+x-4/(x+10)(x-4)

2x-20/(x+10)(x-4)

The value of function g(f(-1)) is -70.

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

The value of functions,

f (x) = -4x - 7

g (x) = x² + 7x - 2

Now, Value of function g(f(-1)) as;

g(f(x)) = g(-4x - 7)

        = (-4x - 7)² + 7(-4x - 7) - 2

        = (4x + 7)² + 7 × -4 × x - 7 × 7 - 2

        = 16x² + 49 + 56x + 28x - 49 - 2

        = 16x² + 84x - 2

Thus, g(f(x)) = 16x² + 84x - 2

Now, To find value of g(f(-1)) we can substitute x = -1,

g(f(-1)) = 16(-1)² + 84(-1) - 2

        = 16 - 84 -2

        = -70

Thus, The value of function g(f(-1)) is -70.

Answer:1/52   One out of 52 (there are 52 cards in a deck, right?)

Step-by-step explanation:

Answer:

Phillipa rode the most in May and rode the least in March.

Distance travelled by Phillipa on her cycle in May = 8 × Distance travelled by Phillipa on her cycle in March  

Step-by-step explanation:

Given:

In April, Phillipa rode 13 . 5 + 8 . 7 + 11 . 1 miles on her bicycle. In March, she rode ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 miles, and in May, she rode 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) miles.

To find: the month when she rode the most and the month when she rode the least

Solution:

Distance travelled by Phillipa on her cycle in April = 13 . 5 + 8 . 7 + 11 . 1 = 65 + 56 + 11 = 132 miles

Distance travelled by Phillipa on her cycle in March = ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 = [tex]\frac{132}{2}=66[/tex] miles

Distance travelled by Phillipa on her cycle in May = 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) = 4 × 132 = 528 miles

So, she rode the most in May and rode the least in March

Distance travelled by Phillipa on her cycle in May = 8 × Distance travelled by Phillipa on her cycle in March

Answer: 7.07 miles

Step-by-step explanation:

Hi, to answer this, first, we have to find the length of the square dog pen.

Perimeter of a square = 4 x sides

Replacing with the value given:

20 = 4 s

Solving for s:

20/4=s

Side = 5 meters

Since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:  

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (in this case length of the diagonal) and a and b are the other sides.  

Replacing with the values given:  

c^2 = 5^2 + 5^2  

c^2 = 25+25

c^2 = 50

c = √50

c = 7.07 miles

Answer:

its going to be (7,9)

Step-by-step explanation:

Answer:

The image of the point after the translation would land the point at (7, 9).

Step-by-step explanation:

When you're moving a point right, imagine adding the number of units you are going right to the x value. When you're moving a point up, imagine adding the number of units you are going up to the y value.

(3 + 4, 8 + 1)

(7, 9)

So, the image of the point of (3, 8) after a translation right 4 units and up 1 unit is going to be (7, 9).

Answer:

He gave 8.57 % of his money for his cousin.

Step-by-step explanation:

In order to calculate the percent that Pedro gave to his cousin, we first need to calculate his total amount, which is given by "x". This is given by:

x = 15 + (x - 15)/5 + 128

x = 15 + x/5 - 3 + 128

x = x/5 + 140

x - x/5 = 140

(5*x - x)/5 = 140

4*x = 700

x = 175

He had originally $175 and gave $15 to his cousing, therefore we can use a rule of three to calculate the percent that he gave to his cousin:

$175 -> 100%

$15 -> y%

175*y = 1500

y = 1500 / 175

y = 8.57 %

The sum of angles in a triangle is 180°. Therefore,

x - 11 + 48 + 90 = 180

x + 127 = 180

x = 53°

Answer:

x = 53

Step-by-step explanation:

Using the information that angles in a triangle add up to 180°, we can set up and equation to find the value of x

⇒ Use the information that angles in a triangle add up to 180°, form an equation

→ x - 11 + 48 + 90 = 180

⇒ Simplify

→ x + 127 = 180

⇒ Minus 127 from both sides to isolate x

→ x = 53

We can substitute the value of x back into x - 11 + 48 + 90 = 180 to see if our value of x is correct, if we end up on 180 on both sides then the value of x is correct

→ x - 11 + 48 + 90 = 180

⇒ Substitute in the value of x

→ 53 - 11 + 48 + 90 = 180

⇒ Simplify

→ 180 = 180

This means that x = 53 is correct

Answer:

The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Step-by-step explanation:

have a great day

There are two ways to find the median, depending on what situation it is.

The first, is to simply arrange the number set into proper numerical format (least to greatest), then count from both sides towards the middle to find the median or middle number.

The latter, is when we have a number set that has an equal amount of numbers. For this, we would again, arrange it into proper numerical format, and the count from both sides up. However, there will be two numbers at the middle. So, what we do, is that we have to add them up and then divide by 2 since there are only those two numbers at the middle. Once, the numbers are added up and divided by 2, you will get the resulting median.

Example: Find the median of the data set below.

1,2,3,4,5,6,7,8,9,9

There are 10 numbers in this data set.

It's already been arranged into proper numerical format.

So, all we have to do is, find the two middle numbers and then add them up and divide.

The two numbers at the middle are: 5 and 6.

Add them up.

5 + 6 = 11

Divide by 2.

11/2 = 5.5

Thus, the median of the data set is 5.5
