Answer:

4m^4 - 8/3m^2 n^2 + 4/9n^4

Step-by-step explanation:

(2m^2 - 2/3n^2)(2m^2 - 2/3n^2)

= 2m^2(2m^2 - 2/3n^2) - 2/3n^2(2m^2 - 2/3n^2)

= 4m^4 - 4/3m^2 n^2 - 4/3m^2n^2 + 4/9n^4

=  4m^4 - 8/3m^2 n^2 + 4/9n^4

Answer:

see below

Step-by-step explanation:

The experimental probability is what you actually rolled

24/60 = 2/5 = 40%

The theoretical probability is what we expect to happen

=number of even numbers / total number of numbers

3/6 = 1/2 = 50%

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

Step-by-step explanation:

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 %

Answer:

It would be an obtuse scalene triangle.

EDITED TO ADD:

When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:

1) Square all 3 sides.

2) Sum the squares of the 2 shortest sides.

3) Compare this sum to the square of the 3rd side.

if sum > 3rd side²   Acute Triangle

if sum = 3rd side²   Right Triangle

if sum < 3rd side²   Obtuse Triangle

6^2 = 36

10^2 = 100

12^2=144

36 + 100 = 136 and this is less than 144 so it is an obtuse triangle.

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

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

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:

(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.

Step-by-step explanation:

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:

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:

The slope-intercept form:

[tex]y = -3x +4[/tex]

Step-by-step explanation:

-To get the slope-intercept equation, you first need to find the slope by using this equation [tex]m = \frac{rise}{run}[/tex] (starting counting from the first point, to the second point) in order to get the slope. After you have the slope, you need to find the y-intercept ( y-intercept is where the line crosses the y axis of the graph, basically). So, to find that, you need look for the point that only crosses the y axis to get the y-intercept. After you have both the slope and y-intercept, you put it in slope-intercept form:

The two points I found from the following graph are:

[tex]( 1, 1)[/tex] and [tex](2, -2)[/tex]

Trick: Since the line of the graph shows that it is down (not up), Start counting down from point [tex]( 1, 1)[/tex] to point [tex](2, -2)[/tex]. Then, find the y-intercept:

[tex]m = \frac{-3}{1} = -3[/tex]

[tex]b = 4[/tex]

Use it to create a slope-intercept form:

[tex]y = mx +b[/tex] (where [tex]m[/tex] represents the slope and [tex]b[/tex] represents the y-intercept)

[tex]y = -3x +4[/tex]

So, therefore the slope-intercept form is [tex]y = -3x +4[/tex] .

Answer:

Correct option: (3) 45

Step-by-step explanation:

Let's call the length of the tangent 'T', the length of the external segment 'E' and the length of the internal segment 'A'.

If we have a secant and a tangent to a circle, we can use the following property:

T^2 = E * (A + E)

If the tangent is 14 inches and the external segment is 4 inches, we have that:

14^2 = 4 * (A + 4)

196 = 4A + 16

4A = 180

A = 45

Correct option: (3)

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
