The number of decimal places

To do this, we simply calculate the number of digits after the decimal points

[tex]0.47 \to 2\ digits[/tex]

[tex]3.2 \to 1\ digit[/tex]

The product is the sum of the digits above 2 + 1 = 3

Hence:

Explanation:

The vertex of f(x) is (-3,4)

The vertex of -f(x) is (-3,-4). Note the y coordinate flips in sign. This is effectively because y = f(x).

Shifting the vertex down 2 units will get us to g(x) = -f(x)-2

So that's how we end up with (-3, -6)

Answer:

V = 211.56 mm

Step-by-step explanation:

The volume of a pyramid :

V = 1/3(Lenght * width * height)

Length = 9mm

Width = 8.2 mm

Height = 8.6 mm

Hence, we have ;

V = 1/3(9 * 8.2 * 8.6)

V = 1/3 * 634.68

V = 211.56 mm

Answer:

x = [tex](-\frac{13}{2} ,0)[/tex] y = (0,26)

Step-by-step explanation:

First find the x intercept

To find the x intercept, substitute 0 for y and solve for x.

[tex](0)-6=4(x+5)[/tex]

Rewrite the equation as [tex]4(x+5)=(0)-6[/tex]

[tex]4(x+5)=(0)-6[/tex]

Subtract 6 from 0.

[tex]4(x+5)=-6[/tex]

Divide each term in [tex]4(x+5)=-6[/tex] by 4.

[tex]\frac{4(x+5)}{4} =\frac{-6}{4}[/tex]

Cancel the common factor of 4.

[tex]x+5=\frac{-6}{4}[/tex]

Simplify [tex]\frac{-6}{4}[/tex]

[tex]x+5=-\frac{3}{2}[/tex]

Subtract 5 from both sides of the equation.

[tex]x=-\frac{3}{2} -5[/tex]

To write [tex]-5[/tex] as a fraction with a common denominator, multiply by [tex]\frac{2}{2}[/tex]

[tex]x=-\frac{3}{2}-5[/tex] · [tex]\frac{2}{2}[/tex]

Combine [tex]-5[/tex] and [tex]\frac{2}{2}[/tex].

[tex]x=-\frac{3}{2} +\frac{-5*2}{2}[/tex]

Combine the numerators over the common denominator.

[tex]x=\frac{-3-5*2}{2}[/tex]

Simplify the numerator.

[tex]x=\frac{-13}{2}[/tex]

Move the negative in front of the fraction.

[tex]x=-\frac{13}{2}[/tex]

x = [tex](-\frac{13}{2} ,0)[/tex]

-----------------------------------------------------------------------------------------------------

Find the y-intercepts.

To find the y-intercept(s), substitute in 0 for x and solve for y.

[tex]y-6=4((0)+5)[/tex]

Add 0 and 5.

[tex]y-6=4 *5[/tex]

Multiply 4 by 5.

[tex]y-6=20[/tex]

Add 6 to both sides of the equation.

[tex]y=20+6[/tex]

Add 20 and 6.

[tex]y=26[/tex]

y = (0, 26)

Answer:

x - y = 4

Step-by-step explanation:

Given

y = x - 4 ( add 4 to both sides )

y + 4 = x ( subtract y from both sides )

4 = x - y , that is

x - y = 4 ← in standard form

Joseph needs to buy 2 bags of grass seed as there are 6 pounds of seeds. Option G is correct.

Let us determine the total area of his lawn by multiplying its length and width.

Length of the lawn = 40 feet

Width of the lawn = 15 feet

Total area = Length × Width

= 40 feet × 15 feet

= 600 square feet

Now, calculate how many pounds of seed are required to cover 600 square feet.

One pound of seed covers an area of 100 square feet.

Therefore, we divide the total area by the coverage area of one pound of seed.

Total pounds of seed needed = Total area / Coverage area per pound of seed

= 600 square feet / 100 square feet

= 6 pounds of seed

Since the seed is sold in five-pound bags, Joseph would need to purchase at least 2 bags of grass seed (each bag containing 5 pounds) to cover his lawn.

Therefore, the correct answer is 2 bags. option G is correct.

Answer:

Choice A

Step-by-step explanation:

A = 1/2 (b1+b2)h

Multiply each side by 2

2A =  (b1+b2)h

Divide each side by (b1+b2)

2A/ ((b1+b2) = h

Answer:

A

Step-by-step explanation:

We have to isolate h on one side.

First, we remove the 1/2 multiplying by H by multiplying both sides by 2

Which results with:

2A = h(b1+b2)

next we have to get rid of (b1+b2) by

dividing both sides by (b1+b2)

2A/(b1+b2)=h

Answer:

1) c. Use only appliances to do the most important task in the house.

2) b. 112kwh

3) b. 111kwh

Step-by-step explanation:

Energy can be defined as the ability (capacity) to do work and it's measured in Joules. The various forms of energy are solar energy, chemical energy, thermal energy, wind energy, nuclear energy, electrical energy, etc.

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

[tex] Power = \frac {Energy}{time} [/tex]

Energy consumption is the total amount of power used by an electronic device per unit time and it's measured in Watt-hour or Kilowatt-hour.

Mathematically, it is given by the formula;

[tex] Energy = power * time [/tex]

Generally, the most economic way to lessen electric consumption is by ensuring only the important electrical appliances are used at all times.

2. Given the following data;

Previous reading = 2156 KWh

Present reading = 2268 KWh

To find how many kilowatt-hour was consumed;

Energy consumption = present reading - previous reading

Energy consumption = 2268 - 2156

Energy consumption = 112 KWh

3. Given the following data;

Previous reading = 5512 KWh

Present reading = 5623 KWh

To find the electrical consumption of Falogme Family;

Electrical consumption = present reading - previous reading

Electrical consumption = 5623 - 5512

Electrical consumption = 111 KWh

Answer:

If we have a figure translated, all the points are translated by the same amount. So, to find the translation, we can look at a single vertex of one of the figures and see how many units it moved in each axis.

a)  Let's look at points B and B'.

B = (-3, 4)

B' = (-1, 3)

The translation will be given by:

B' - B

(-1, 3) - (-3, 4) = (-1 -(-3), 3 - 4) = (1 + 3, -1) = (2, - 1)

Then, each point (x, y) in the original figure, is translated to (x + 2, y - 1)

Then the correct point is C.

b) Let's look at points B and B' again.

We can see that:

B = (1, 6)

B' = (6, -2)

Again, the translation is given by:

B' - B

(6, -2) - (1, 6) = (6 - 1, -2 - 6) = (5, - 8)

Then, any point (x, y) in the original figure, is translated to (x + 5, y - 8)

Then the correct option is C

Step-by-step explanation:

The number of ways we can choose three different numbers in order for a unique code for this case is 2730

A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

We can use combinations for this case,

Total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total number of ways,

⇒ [tex]^{m} C_{k} =[/tex] m! / (m - k)! k!

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, total number of choices in that case would be:

⇒ [tex]^{m} P_{k} =[/tex] m! / (m - k)!

This is called permutation of k items chosen out of m items (all distinct).

Given that:

The considered lock as a 3 number code

There are 15 numbers available.

None of the number can repeat.

In a lock, the order of the way numbers are arranged matters.

Because of no repetition allowed, we can simulate this situation as:

The number of ways we can choose 3 numbers out of 15 numbers with order = The number of different ways we can choose three different numbers in order for a unique code.

And we have:

The number of ways we can choose 3 numbers out of 15 numbers with order is,

⇒  [tex]^{m} P_{k} =[/tex] m! / (m - k)!

⇒  [tex]^{15} P_{3} =[/tex] 15! / (15 - 3)!

            = 15! / 12!

            = 2730

Thus, The number of ways we can choose three different numbers in order for a unique code for this case is 2730
