Answer:

JN = 18.6

Step-by-step explanation:

Theorem:  The length of the midsegment of a trapezoid is the average of the bases.

[tex]JN = \frac{15.4 + 21.8}{2}[/tex]

       [tex]= \frac{37.2}{2}[/tex]

       = 18.6

See how easy that is when you know the theorem.

Step-by-step explanation:

Circumference

Circumference of a circle is calculated by the formula:

= π * diameter

= 3.14 * 52

= 163.28 units

Area

Area of a circle is calculated by the formula:

= π * radius²

Radius = DIameter / 2

= 52 / 2

= 26 units

Area = 3.14 * 26 * 26

= 2,122.64‬ units²

Answer:

100

Step-by-step explanation:

Give the equation :

y = 100x

The equation above is expressed using the general formof a direct variation ; where ;

a varies directly as x equals

a = kx

Where, k = constant of proportionality

Comparing this with the equation above, we can conclude that, the above equation has a constant of variation, k which is equal to 100

Answer:

Step-by-step explanation:

(a + 3)×(−2a² + 15a + 6b²) =

= a×(−2a² + 15a + 6b²) + 3×(−2a² + 15a + 6b²) =

= -2a³ + 15a² + 6ab² - 6a² + 45a + 18b² =

= -2a³ + 9a² + 6ab² + 45a + 18b²

The product [tex](a+3) * (-2a^2+15a+6b^2)[/tex] is [tex]-2a^3+9a^2+ 45a +6ab^2 + 18b^2[/tex]

The product of numbers or expressions is gotten by multiplying them

The product expression is represented as:

[tex](a+3) * (-2a^2+15a+6b^2)[/tex]

Expand the expression

[tex]-2a^3+15a^2+6ab^2 -6a^2 + 45a + 18b^2[/tex]

Collect like terms

[tex]-2a^3+15a^2 -6a^2+ 45a +6ab^2 + 18b^2[/tex]

Evaluate the like terms

[tex]-2a^3+9a^2+ 45a +6ab^2 + 18b^2[/tex]

Hence, the product [tex](a+3) * (-2a^2+15a+6b^2)[/tex] is [tex]-2a^3+9a^2+ 45a +6ab^2 + 18b^2[/tex]

Answer:

Given that is a 45-45 triangle, the hypotenuse should be x[tex]\sqrt{2}[/tex], so in this case. The hypotenuse should be 3[tex]\sqrt{2}[/tex], and the other side lengths 3. I see no other way of it going other than that one; I hope I helped at least a bit!

Step-by-step explanation:

Answer:

base =3in and hypotenuse =3√2

Step-by-step explanation:

relationship between perpendicular and hypotenuse is given by sin angle

sin 45=p/h

sin45=3in/h

h=3in/sin45=3√2 inch

relationship between perpendicular and base is given by tan angle

tan45=P/b

b=3in/tan45=3in

Answer:

At Z-Mart, after the discount it is 7/8 of the original price of 225,

at ABC Sports the final price is 200,

and at Bike World, after the discount it is 3/4 of the original price of 265

so

we multiply 225 by 7/8 to get 196.88,

which is lower than ABC Sports,

and then we multiply 265 by 3/4 to get 198.75, which is higher than Z-Mart

so Z-Mart or A) is correct.

Answer:

Given function:

a)

Th x-intercept found when g(x) = 0

Solve the equation to find the values of x:

The x-intercepts are (3 + √7, 0) and (3 - √7, 0)

b)

Solve as above:

The left side is a square of a number which is always positive, the right side is negative.

It means there is no solution, so no-x-intercepts.

The graph of the function lies above the x-axis.

Answer:

124.8 Inches

Step-By-Step

1/2 0.835 Inches = 0.4175

r = 0.4175

h = 0.077

A=2πrh+2πr^2

A=2π(0.4175)(0.077)+2π(0.4175^2)

A = 3.12

Nickel = 5 Cents

$2 = 200 Cents

200 / 5 = 40

(3.12)(40) = 124.8 In

Answer:

The answer is 0.8 in^2

Step-by-step explanation:

Data

diameter = 0.835 in

thickness = 0.077in

Roll of $ 2.00

Procedure

1.- Find the total number of nickels

# of nickels = 2/ 0.05

# of nickels = 40

2.- Calculate the Circumference

C = 2*pi*r

r = 0.077/2

r = 0.0385

C = 2*3.14*0.0385

C = 0.242 in

3.- Calculate the area of the thickness

Area = 0.242* 0.077*40

Area = 0.745 in^2

4.- Calculate the area of the base and the top

Area = 2*pi*r^2

Area = 2*3.14*(0.0382)^2

Area = 0.0093 in^2

5.- Calculate the total area of the roll

Total area = Area of the thickness + Area of the base and top

Total area = 0.745 + 0.0093

Total area = 0.7543 in^2 This is the result

Rounding to the nearest tenth = 0.8 in^2

Answer:

y=-2/5x+2

Step-by-step explanation:

use y = mx + b

m = slope = rise/run = 2/5

b = y-intercept when x is zero (0,y) = (0,2) = 2

since the line is going down, the slope has to be negative.

Answer How many solutions does the nonlinear system of equations graphed below have?

Look at the number of points where the graphs intersect each other...the points where the graphs of the functions cross each other are the solutions to the system.

Upon looking, you should see 4 points where the graphs intersect, so there are 4 solutions to the non-linear system of equations.

Answer:

•cos(s+t) = cos(s)cos(t) - sin(s)sin(t) = (-⅖).(-⅗) - (√21 /5).(⅘) = +6/25 - 4√21 /25 = (6-4√21)/25

•cos(s-t) = cos(s)cos(t) + sin(s)sin(t) = (-⅖).(-⅗) + (√21 /5).(⅘) = +6/25 + 4√21 /25 = (6+4√21)/25

cos(t) = ±√(1 - sin²(t)) → -√(1 - sin²(t)) = -√(1 - (⅘)²) = -⅗

sin(s) = ±√(1 - cos²(s)) → +√(1- cos²(s)) = +√(1 - (-⅖)²) = √21 /5

Answer:

x=25
