If hypotenuse of an isosceles right triangle is [tex]4\sqrt{2}[/tex] units, then the area of the triangle is 8 square units

Given,

The hypotenuse of an isosceles triangle =[tex]4\sqrt{2}[/tex]

An isosceles triangle is a triangle that has at least two sides of equal length

Consider the two equal sides as x

According to Pythagoreans theorem

[tex]x^{2} +x^{2} =(4\sqrt{2})^{2} \\2x^{2} =32\\x^2=16[/tex]

x=4 units

We know,

Area of two isosceles right triangle equal to the area of the square with same length

Area of the square = [tex]x^{2} =4^{2}=16[/tex] square units

Then the area of the triangle =[tex]\frac{16}{2}=8[/tex] square units

Hence, if hypotenuse of an isosceles right triangle is [tex]4\sqrt{2}[/tex] units, then the area of the triangle is 8 square units

The solution to the inequality is x < 3.3

The given parameters are:

Perimeter < 18.7 feet

Side lengths: 4.1 ft 4.9 ft 6.4 ft x ft

The perimeter of a shape is the sum of the side lengths

So, we have

Perimeter = 4.1 ft + 4.9 ft + 6.4 ft + x ft

Remove the unit

So, we have

Perimeter = 4.1+ 4.9 + 6.4 + x

Evaluate the sum

Perimeter = 15.4 + x

Recall that

Perimeter < 18.7 feet

So, we have

15.4 + x < 18.7

Subtract 15.4  from both sides

x < 3.3

Hence, the solution to the inequality is x < 3.3

The equation of the parabola is y = (-3/2)x + 1.

The general vertex form of the equation of a parabola is y = a(x - h)2 + k

where (h, k) are the coordinates of the vertex

Here, we are given that vertex = (0, 1)

Thus, the equation of the parabola is-

y = a(x - 0)2 + 1

y = 2ax + 1

Also, we are given that the parabola passes through (12, -17).

Thus, (12, -17) must satisfy the equation of the parabola

⇒ -17 = 2a(12) + 1

-17 = 24a + 1

24a = -17 -1

24a = -18

a = -18/24

a = -3/4

Thus, the equation of the parabola becomes-

y = 2(-3/4)x + 1

y = (-3/2)x + 1

Answer:

Equation is 15(x-20) = 945

x = $83

Step-by-step explanation:

The cost of each lesson is $x

The discounted cost = x-20

Since 15 lessons cost 945,

the equation is

15(x-20) = 945

Simplifying by multiplying the term in brackets by 15:

15x - 15(20) = 945

15x - 300 = 945

Adding 300 on both sides isolates the 15 x term

15x = 945 + 300 = 1245

15x = 1245

Dividing both sides by 15 ,
x = 1245/15 = 83

So cost of lesson before discount is $83

Answer:

2x + 3y = 13

4x - y = -2

In the second equation, subtract 4x from both sides.

-y = -2 - 4x

Divide both sides by -1.

y = 2 + 4x

Put this into the first equation in place of y.

2x + 3(2 + 4x) = 13

Multiply everything in the parenthesis by 3.

2x + 6 + 12x = 13

Combine like terms.

14x + 6 = 13

Subtract 6 from both sides.

14x = 7

Divide 14 on both sides.

x = 7 / 14

x = 0.5

Put this into the second equation in place of x.

4(0.5) - y = -2

2 - y = -2

Subtract 2 from both sides.

-y = -4

Divide both sides by -1.

y = 4

So x = 0.5 and y = 4.

As t increases the curve is changing according to the plot points given by the parametric equations.

The coordinates of the points that make up a geometric object, such as a curve or surface, are frequently expressed using parametric equations; in this case, the equations are collectively referred to as a parametric representation or parameterization (alternatively spelled as parametrisation) of the object. It describes a collection of numbers that represent functions with one or more independent variables. The parameters used here are the independent variables. For the representation of the coordinates that make up geometric objects like curves and surfaces, parametric equations are used. Additionally, a curve that is not a function can be drawn using parametric equations.

The equations are

The time taken by both to mow the lawn is 36 minutes.

This is a question of time and work.

It is given that:-

Time taken by boy to mow the loan = 90 minutes.

Time taken by girl to mow the loan = 60 minutes.

We have to find the time taken by both of them together to mow the lawn.

LCM(60,90) = 180

Let the total work to be done to mow the lawn be 180 units.

Hence,

Efficiency of boy = 180/90 = 2 units

Efficiency of girl = 180/60 = 3 units

Total efficiency = 2 + 3 = 5 units.

Hence, time taken by both of them to mow the lawn = 180/5 = 36 minutes.

As per the question statement, our concerned equation is  [tex][\frac{1}{5(10x-5)} =(5x-1)][/tex].
