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

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

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.

4*5=20

16=4/5 (80%) so 20= 5/5 (100%)

Answer: 20

Step-by-step explanation:

80/100 x Y = 16

Cross multiply

80Y = 1600

Divide both sides by 80

Y = 1600/80

Step-by-step explanation:

Answer:

89°

Step-by-step explanation:

The sum of all 3 angles in a triangles equals 180. If you add 50 to 41, you get 91. Then, you subtract 91 from 180, getting 89 degrees. Next, you square 89, add 170, subtract 12, add 3,218, subtract 3376, and find square root.

Answer:

x can equal any number between 0 and 8. This also includes 8.

Step-by-step explanation:

As noted in the problem, x is more than -1 (x > -1)

So we can infer that -1 and anything past it to the left is not a viable answer.

As noted in the problem, x is lesser than or equal to 8 (x ≤ 8) meaning that anything past 8 to the right will not be a viable answer.///

well, we can say that √2 and √7 are irrational numbers, they do not provide a value that can be written in a "ration" or fractional.

we can also say that √2 * √7 is √(14), which is also irrational.

However, how about √7 * √7, that's √7² or namely just 7, and that's a rational, so nope, not always.

The probability that the bill will be less than $100 is 7%

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

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

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

Answer:

for the first line let (-4,-3) be (x1,y1) and (8,0) be x2,y2.

now,

slope (m1) = (y2-y1)/ (x2-x1)

or, m1= 0-(-3)/ 8-(-4)

or, m1=3/12=1/4

again, for line two consider (0,2) as x1,y1 and (-1,6) be (x2,y2)

apply the same formula and find the slope(m2)

m2=6-2/-1-0

or, m2=4/-1

for b) m1 multiply m2

or 1/4 x 4/-1

=-1 so it is perpendicular

Step-by-step explanation:

for a we simply apply the formula of slope considering the given points as x1,y1 and x2,y2 respectively.

while for the b number if m1 x m2 =-1 the line is considered to be perpendicular.

similarly, if m1=m2 then it is considered to be parallel.

here m1 is slope of the first line, m2 is slope of second line and m3 is the slope of the third line
