Express in scientific notation: 8346000

Step-by-step explanation:

If each block is considered as 1 unit,

the zeroes of f(x) are -3 and 7.

At x = 2, h(x) is at its absolute maximum. In the interval 2 <= x <= 5, the function h(x) is decreasing.

Answer:

C=29

Step-by-step explanation:

a^2 + b^2 = c^2

21^2 + 20^2 = c^2

441 + 400 = c^2

841 = c^2

\sqrt(841) = \squrt(c^2)

29 = c

Answer: 1 /12 pounds each

Step-by-step explanation:

Alexis has a 5/12 pound bag of apples and 5 friends to divide them amongst.

The number of pounds each friend receives is the number of pounds Alexis has divided by the number of friends she has:

= 5/12 ÷ 5

= 5/12 * 1/5

= 5 / 60

Take the fraction to the lowest form by dividing by 5:

= 1 / 12

Hint: When dividing a fraction by a number, you can instead multiply that fraction by the inverse of that number.

First, we’ll need to find the slope.

(-5,-4) (-2,-7)

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

m = [tex]\frac{-4 - (-7)}{-5-(-2)}[/tex]

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

m = -1

Next, substitute these values into the point slope equation:

y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])

y - (-7) = -1(x - (-2))

y + 7 = -1(x + 2)

Now, convert to slope intercept form (y = mx + b):

y + 7 = -1x -2

  -7           -7

y = -1x - 9

Answer:

100,000

Step-by-step explanation:

Answer:

100,000

Step-by-step explanation:

im not sure if its correct

Step-by-step explanation:

Given

Perimeter of square (P) = 64 cm

first calculating the length

P = 4L

64 = 4L

L = 64 / 4

Therefore L = 16 cm

Now Finally Calculating Area

Area of square

=L²

= (16)²

= 256 cm²

Hope it helps :)

Answer: 256

6Step-by-step explanation: if the perimeter is 64 that means 16+16+16+16 so that would be 16×16 which is

Answer:

yes!

Answer:

4 (14+26)

Step-by-step explanation:

in order to multiple a sum you must add the 2 numbers to get the sum then multiply.

in order to do so you must add Parentheses.

(14 + 26)

then you multiply

4 ( 14 + 26 )

Answer:

4(14+26)

Step-by-step explanation:

Here you go! 4 times the SUM of 14 and 26 would mean, you have the addition problem now multiply that by 4 but don't solve the addition problem.

Answer:

3952.8$

Step-by-step explanation:

61$ : 100 = x : 60% (since it is 40% off, the remaining is 60% of the price)

100x : 61 x 60

100x : 3360

3360 divided by 100

x = 36.6

36.6 : 100% = x 108%

100x : 36.6 x 108

x = 3952.8

3952.8 divided by 100

39.528

Answer:

£103.70

Step-by-step explanation:

Payment per hour = £8.50

Overtime payment = 1.4 × 8.50

= £11.90

Ben worked for 11 hours.

Normal time = 8 hours

Overtime = 3 hours

Total earnings = (8 hours × 8.50) + (3 hours × 11.90)

= £68 + £35.7

= £103.70

Ben earned £103.70 for working for 11 hours

First, solve the power:

2^3 = 2 * 2 * 2 = (2 * 2) * 2 = 4 * 2 = 8

Next, multiply:

8 x 7 = 56

56 is your answer.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}-2x-5y=20\\ y=\frac{4}{5}x+2\end{bmatrix}[/tex]

Please check the attached graph.

On the attached diagram:

The blue line represents the line -2x - 5y = 20

The red line represents the line y = 4/5x + 2

It is clear from the graph that both the graphs meet or intersect each other at the point (-5, -2).

In other words,

(x, y) = ( -5, -2) is the point of intersection of the two lines.

We know that the point of intersection of the two lines is the solution of the system of equations.

Therefore, the solution to the system of equations will be:

(x, y) = ( -5, -2)

The solution to the system of equations using the elimination method:

Given the system of equations

[tex]\begin{bmatrix}-2x-5y=20\\ y=\frac{4}{5}x+2\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}-2x-5y=20\\ -\frac{4}{5}x+y=2\end{bmatrix}[/tex]

Multiply  -2x - 5y = 20 by 2:  -4x-10y=40

Multiply y = 4/5x + 2 by 5: -4x+5y=10

so

[tex]\begin{bmatrix}-4x-10y=40\\ -4x+5y=10\end{bmatrix}[/tex]

now subtracting

[tex]-4x+5y=10[/tex]

[tex]-[/tex]

[tex]\underline{-4x-10y=40}[/tex]

[tex]15y=-30[/tex]

solve 15y = -30 for y

[tex]15y=-30[/tex]

Divide both sides by 15

[tex]\frac{15y}{15}=\frac{-30}{15}[/tex]

[tex]y=-2[/tex]

For -4x-10y=40, plug in y = -2

[tex]-4x-10\left(-2\right)=40[/tex]

[tex]-4x+20=40[/tex]

simplify

[tex]-4x=20[/tex]

divide both sides by -4

[tex]\frac{-4x}{-4}=\frac{20}{-4}[/tex]

Simplify

[tex]x=-5[/tex]

Therefore,

The solution to the system of equations will be:

(x, y) = ( -5, -2)
