Answer:

Vincent’s plane is cruising at an altitude of 3.2 × 10^4 feet.

Convert the number to standard notation.

3.2 × 10^4 feet  

=

3.2 • 10,000 feet

=

32,000 feet

Step-by-step explanation:

This is the sample answer from Edmentum.

Answer:

Question 1 part a =

Vincent’s plane is cruising at an altitude of 3.2 × 104 feet.

Convert the number to standard notation.

3.2 × 104 feet  

= 3.2 • 10,000 feet

= 32,000 feet

Part b =

Felix’s skydiving altitude is 1.28 × 105 feet.

Convert the number to standard notation.

1.28 × 105 feet  

= 1.28 • 100,000

= 128,000 feet

Part c =

Subtract the two altitudes to find the difference.

128,000 feet − 32,000 feet = 96,000 feet

The difference of their altitudes is 96,000 feet.

Part d =

The difference of the altitudes is 96,000 feet.

Covert 96,000 to scientific notation:

96,000 feet = 9.6 × 104 feet

Question 2 part a  =

Vincent’s plane’s altitude is 3.2 x 10^4 feet.

Felix’s skydiving altitude is 1.28 x 10^5 feet.

Transform 3.2 x 10^4  so its exponent matches the power of 10 in 1.28 x 10^5.

To do so, multiply and divide the number by 10.

3.2 x 10^4 = 10/10 x 3.2 x 10^4

                 = 3.2/10 x 10^4 x 10

                 = 0.32 x 10^5

Part b =

Calculate the difference of the two altitudes:

1.28 × 105 – 0.32 × 105

=  (1.28 – 0.32) • 105

= 0.96 • 105

The difference of their altitudes is 0.96 •105 feet.

Part c =

The difference of Vincent’s and Felix’s altitudes is 0.96 x 10^5 feet.

To convert the answer to scientific notation, multiply and divide the number by 10.

0.96 x 10^5 = 10/10 x 0.96 x 10^5

                   = (0.96 x 10) x (10^5 x 10^-1)

                   = 9.6 x 10^4 feet

In scientific notation, the difference of Vincent’s and Felix’s altitudes is 9.6 x 10^4 feet.

Question 3 =

The altitudes are the same. That means you can subtract numbers given in scientific notation using either of two methods: convert them to standard notation and then perform the subtraction, or subtract the numbers in scientific notation without converting them to standard notation.

Answer:

Step-by-step explanation:

if (x,y) is the centroid. Then x=(x1+x2+x3)/3,y=(y1+y2+y3)/3

5.

x=(-2+4+10)/3=4

y=(6+0+6)/3=4

centroid=(4,4)

6.

x=(3+5-2)/3=2

y=(3-1+1)/3=1

centroid=(2,1)

Answer:

(x - √7*√x) / (x - 7)

Step-by-step explanation:

I suppose your expression is √x / (√x + √7)

(√x * (√x - √7)) / ((√x + √7) * √x - √7)) = (√x * √x - √7 * √x) / (x - 7)

= (x - √7*√x) / (x - 7)

Step-by-step explanation:

0*(1/3125)+1*(4/625)+2*(32/625)+3*(128/625)+4*(256/625)+5*(1024/3125)

The expected value is an extension of the weighted average in probability theory. The expected value for the given binomial distribution is 4.

The expected value is an extension of the weighted average in probability theory. Informally, the anticipated value is the arithmetic mean of a large number of independently chosen random variable outcomes.

Expected value, E(x) = ∑(Px)

where P is the probability and x is the random distribution value.

The expected value for the given binomial distribution is,

Expected value = Random variable × Probability

E(x) = ∑(Px)

= 0(1/3125) + 1(4/625) + 2(32/625) + 3(128/625) + 4(256/625) + 5(1024/3125)

= 0 + (4/625) + (64/625) + (384/625) + (1024/625) + (5120/3125)

= 0 + 0.0064 + 0.1024 + 0.6144 + 1.6384 + 1.6384

= 4

Hence, the expected value for the given binomial distribution is 4.

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

So the sum of the angles is 18 × 90 = 1620

the formula to find number of sides is n which is sides - 2 into 180 equals sum of interior angles

(n-2)*180 = 1620

n-2 = 1620/180

n- 2 = 9

n = 11

Answer: 10) Fourth option

Step-by-step explanation:

10) [tex]\frac{t^2+2t-24}{t^2-36}[/tex]

Factor t^2 + 2t - 24

What two numbers add to 2 and multiply to -24?

6 and -4 so

(t + 6)(t - 4) is the factored form

t^2 - 36 factored is  => because of a^2 - b^2 = (a - b)(a + b)

[tex]\frac{(t + 6)(t - 4)}{(t + 6)(t - 6)} = \frac{t-4}{t-6}[/tex]

Since we cancelled out be t + 6, t + 6 ≠ 0, t ≠ -6

And since the denominator is t - 6, t - 6 ≠ 0, t ≠ 6

[tex]\frac{t-4}{t-6}[/tex] , t ≠ -6, t ≠ 6

Answer:

-3x-3

Step-by-step explanation:

Answer:

Adding them together. x = 3/2, y = 8

Step-by-step explanation:

Adding because we want to get rid of a variable. If we add, 2x + 6x = 8x, 1/2 * y + (-1/2 * y) = 0, and 7 + 5 = 12. Adding gets rid of the y variable.

By adding we get that 8x = 12 which gives us x = 12/8 = 3/2

Substituting this back into either equation will give us y = 8.

Answer:

y = 3x² + 15x + 12

Step-by-step explanation:

A quadratic function in standard form is

y = ax² + bx + c ( a ≠ 0 )

Given

y = 3(x + 4)(x + 1) ← expand the factors using FOIL

  = 3(x² + 5x + 4) ← distribute parenthesis by 3

  = 3x² + 15x + 12

Formula: SOHCAHTOA

TOA: tan = opposite/adjacent

31 / 23 = 1.3478

y = 53 degrees

Answer:

No mode​

Step-by-step explanation:

The mode is the statistical method in which the most repetitive number should be considered

Like if we take an example

1,1, 2, 2, 2, 4, 4,4,4

So here the mode is 4 as 4 is repeated 4 times

But in the given situation there is no mode as every number is written single time

y - intercept = -5/2

x-intercept = -2

Step-by-step explanation:

-5x - 4y = 10

At y-intercept , x = 0

0 - 4y = 10

       y = 10/-4

       y = -5/2

At x-intercept, y = 0

   -5x  - 0 = 10

           -5x = 10

              x = 10/-5

Answer:

-13.8y

Step-by-step explanation:

Since these all have the same variable you don't need to worry that much. Let's take away the y to make it easier. Now you just subtract normally.

1.8 - 9.3

A trick that I use is that I subtract 9.3 - 1.8, and then add a negative sign. So that is -7.5

Then, subtract -7.5-6.3. You add these because they have the same symbol. So it is -13.8

We can't forget about the variable!! So it is -13.8y

Given:

Dimensions of a cuboid = 36 cm × 75 cm × 80 cm.

To find:

The edge of a cube whose volume is equal to the volume of the given cuboid.

Solution:

We know that the volume of a cuboid is

[tex]Volume=length\times breadth \times height[/tex]

[tex]V_1=36\times 75 \times 80[/tex]

[tex]V_1=216000[/tex]

The volume of a cube is

[tex]Volume=a^3[/tex]

Where, a is the side length of the cube.

The volume of cube and cuboid are equal. So,

[tex]a^3=216000[/tex]

[tex]a=\sqrt[3]{216000}[/tex]

[tex]a=60[/tex]

Therefore, the measure of edge of the cube is 60 cm.
