Answer:

the answer is 8

Step-by-step explanation:

1. plug in 5 where there is an x: 4(5-3)+5(5)-[tex]5^{2}[/tex]

2. solve everything out and cancel: 4(2)+25-25

3. 4(2)=8

Step-by-step explanation:

Given that:

Evaluate 4(x-3)+5x-x^2 for x = 5

⇛4(5-3)+5(5)-5²

⇛4(2) + 25 - 5*5

⇛8 + 25 - 25

⇛8 - 0

Answer:

The sum of the solutions = 1/2

Step-by-step explanation:

4m^2 - 2m - 6 = 0

Factor out 2

2( 2m^2 -m-3) =0

2 ( 2m-3)(m+1) =0

Using the zero product property

2m-3 =0           m+1 =0

2m =3              m=-1

m = 3/2              m=-1

Adding the solutions

Answer:

  1/2

Step-by-step explanation:

A quadratic equations that has solutions p and q can be factored as ...

  (x -p)(x -q) = 0

When this is expanded, it becomes ...

  x^2 -(p+q)x +pq = 0

That is, the opposite of the x-coefficient is the sum of the solutions.

__

We can put your quadratic into this form by dividing by the leading coefficient, 4.

  (1/4)(4m^2 -2m -6) = 0

  m^2 -1/2m -3/2 = 0

The coefficient of the linear term is -1/2. This tells us the sum of the solutions is -(-1/2) = 1/2.

Answer:

B. 40

Step-by-step explanation:

if x=300, it means x>200, then b(x)=0.1(x-200)+30; ⇔ b(x)=0.1*100+30= 40 [USD].

The bill for a person who uses 300 kWh in a month is $40.

Option B is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

For a person who uses 300 kWh in a month, we need to use the second part of the function:

b(x) = 0.10(x - 200) + 30, x > 200

Substituting x = 300, we get:

b(300) = 0.10(300 - 200) + 30

b(300) = 0.10(100) + 30

b(300) = 10 + 30

b(300) = 40

Therefore,

The bill for a person who uses 300 kWh in a month is $40.

Answer: IMA LET YOU KNOW THIS THAT ITS ACTUALY  -3 8/10

Step-by-step explanation:

If Parin digs a hole at a rate of 5/6 feet every 15 minutes. After digging for 45 minutes, Parin places a bush in the hole that fills exactly 3/4 feet of the hole. Then the elevation of the hole after placing the bush in the hole is [tex]1\frac{3}{4}[/tex]

Two or more expressions with an Equal sign is called as Equation.

Given that Parin digs a hole at a rate of 5/6 feet every 15 minutes.

In 45 minutes, Parin digs a hole of 5/6×45/15

5/6×3

5/2

The total depth of the digging = 5/2

Now, 3/4 feet dig is filled by bush, so the remaining elevation of the depth, = 5/2- 3/4

five by two minus three by four.

5/2-3/4

Take LCM of 2 and 4

(10-3)/4

7/4

the elevation of the hole after placing the bush in the hole is 7/4.

Now we can write in mixed fraction [tex]1\frac{3}{4}[/tex]

Hence elevation of the hole after placing the bush in the hole is [tex]1\frac{3}{4}[/tex]

Find the equation of the line shown in the picture.

Answer:

y = x + 6

Answer:

firstly you have to find the slope of the line.

Step-by-step explanation:

for thus, use the number which is on the coordinate system like x and y. the slope is (10-6)/(4-0) =1 so m=1

the equation should be on this form y-y1=m"(x-x1)

then put the value of y and x from equation.

when the x is 4 the y have to be 10

y-10=1*(x-4)

finally the equation is y=x+6

Answer:

1. Diameter of a semicircles =14cm

Radius or semicircle =7cm

*Area if circle =pi radius 2

=22/7 × 7×7cm 2

=154cm 2

But semicircle is half if a circle so,

Area of a semicircle =1/2 ×154cm2

=77cm2

2. Radius of the circle =1cm

Area of the circle=pi radius 2

=3.14×1×1

=3.14cm2

3.Diameter of a circular lawn=10m

Radius of the circular lawn =5m

Area of the circular lawn =pi radius2

=3.14×5m×5m

=78.5m2

[tex]\sqrt{5^{2} }[/tex]×[tex]\sqrt{2}[/tex]

since 5 is squared the square root cancels out

Answer:

Yes

Step-by-step explanation:

The way the equation is written in point-slope form is:

[tex]y-y1=m(x-x1)[/tex]

The way we write an equation in slope-intercept form is:

[tex]y=mx+b[/tex]

We can change point-slope form to slope-intercept form by first distributing the m and then adding y1 to both sides of the equation. When we do this we will get:

[tex]y=mx-(m*x+y1)[/tex] where [tex](m*x+y1) = b[/tex]

which is now in slope intercept form.

The surface area of the triangular prism ramp is: 1,020 ft².

Surface area = 1/2(base area × height)

The triangular prism has the following dimensions:

base area = 20 × 12 = 240 ft²

height = 8.5 ft

Plug the values into the formula:

Surface area = 1/2(240 × 8.5)

Surface area = 1/2(2,040)

Surface area = 1,020 ft²
