The length of EP is 8 units, in the triangle.

What is are of the triangle?

The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.

In geometry, a line segment bisecting one side of a triangle by connecting one of its vertices to the opposing side's midpoint is referred to as the triangle's median. Every triangle has exactly three medians, one from each vertices. The centroid of the triangle is where these medians cross.

Given in the diagram in PU = 4units.

We know that PU is 1/3rd of the side EU

So the length of EP = 2* PU = 2*4 = 8unit.

Hence the length of EP is 8unit.

Step-by-step explanation:

f(x) = 3x - 5

Given that, f(x) = 4

So, we can find x by inserting the value of f(x) in the above equation.

4 = 3x - 5

Add 5 to both sides

4 + 5 = 3x

9 = 3x

Divide 3 to both sides

Step-by-step explanation:

Answer: x = 85° ,   y =45°

Step-by-step explanation:

x + 95 = 180°

x = 180° - 95°

x = 85°

In a triangle,

50° + x + y = 180°

50° + 85° + y = 180°

135° + y = 180°

y = 45°

From the above given expression

x = 35°

y = 95°

In a straight line, the angle is 180°

given angles are  50° internal angle and 95° external angle

then   x + 50° + 95° = 180°

          x + 145° =  180°

          x = 180° - 145°

          x = 35°

so in a triangle total angle is 180°

then  50° + x + y = 180°

         50° + 35° + y 180°

         y = 180° - 85°

         y = 95°

f(x) = (7/4)ˣ is the equivalent exponential function to f(x) = (4/7)⁻ˣ

Equivalent exponential functions are functions that work the same even though they look different.

If two exponential functions are equivalent, then the two functions will have the same value when we substitute the same value(s) for the variable(s)

Given: f(x) = (4/7)⁻ˣ

Expression of this type can be written in two possibles:

1. By interchanging the numerator and denominator, and then changing the negative power to positive. Thus:

f(x) = (4/7)⁻ˣ = (7/4)ˣ

2. By writing the expression as a reciprocal. Thus:

f(x) = (4/7)⁻ˣ =  1/(4/7)ˣ

Therefore, the equivalent exponential function is f(x) = (7/4)ˣ. The 1st option is the answer

Answer:

x - y = 3

Step-by-step explanation:

Answer:

2x - 5y = 20

Step-by-step explanation:

Standard form should look like:

Ax + By = C

and the numbers A,B, and C have to be whole numbers (actually integers, because negative is okay too except A has to be positive)

You have been given a point and the slope. There is a shortcut, fill-in-the-blank equation called point-slope that you can just fill in a point and the slope. Then we can change that equation into standard form.

Point-slope equation:

y - Y = m(x - X)

Fill in (5, -2), which is the (X, Y). 5 in place of X and -2 in place of Y. Fill in 2/5 for the m which is slope.

y - Y = m(x - X)

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

simplify, and distribute.

y + 2 = 2/5x - 2

Multiply through by 5 to get rid of the fraction.

5y + 10 = 2x - 10

Subtract 10.

5y = 2x -20

Subtract 2x.

5y - 2x = -20

Rearrange the terms.

-2x + 5y = -20

Multiply through by -1 (because that A has to be positive)

2x - 5y = 20

The equation in standard form is:

   Amount = $1821.25

10) Rate is 9.5%

11) Time is 4 years

12) Noah pays $6591 as interest on his car loan

What is simple interest?

Simple interest ( SI) is the interest earned on a certain principal at a certain rate over a certain period of time,

If P is the principal, rate is r %, time is t years,

SI = [tex]\frac{p \times r \times t}{100}[/tex]

Adding Principal and simple interest will give the amount

7) Principal = $900

   Rate = 11 %

  Time = 3 months = [tex]\frac{3}{12} = \frac{1}{4}[/tex] years

    Simple Interest = [tex]\frac{900 \times 11 \times 1}{100 \times 4}[/tex]

                              = [tex]\frac{99}{4}[/tex]

                              = $24.75

  Amount = $(900 + 24.75) = $924.75

8) Principal = $8417

   Rate = 18 %

   Time = 1 months = [tex]\frac{1}{12}[/tex] years

    Simple Interest = [tex]\frac{8417 \times 18 \times 1}{100 \times 12}[/tex]

                              = $126.255

   Amount = $(8417 + 126.255) = $8543.255

9)  Principal = $1550

  Rate = [tex]8\frac{3}{4}[/tex] % = [tex]\frac{35}{4}[/tex] %

  Time = 24 months = 2 years

    Simple Interest = [tex]\frac{1550 \times 35 \times 2}{100 \times 4}[/tex]

                              = $271.25

   Amount = $(1550 + 271.25) = $1821.25

10) Let the rate be r %

Principal = $7200

  Rate = r %

   Time = 15 months = [tex]\frac{15}{12} = \frac{5}{4}[/tex]  years

    Simple Interest = [tex]\frac{7200 \times r \times 5}{100 \times 4}[/tex]

                              = $90r

By the problem,

90r = 855

[tex]r = \frac{855}{90}[/tex]

r = 9.5%

11)  Let the time be t years

What are the zeros of the function algebraically?

The zeros of a function are the points at which the function's value is zero. These are obtained algebraically by setting the function to zero and solving the quadratic.

We have,

f(x) = -25x⁴ + 9x²

= (25 • (x⁴)) -  32x²

= (5)²x⁴ -  (3)²x²

= 25x⁴ - 9x²

= x² • (25x²- 9)

  A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

25  is the square of  5

Using Pythagorean Theorem, value of x is 27.2.

The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a² + b², are equal to the squares on the legs. To determine the undiscovered side of a right-angled triangle, utilise the Pythagoras theorem. The hypotenuse (third side) of a right-angled triangle, for instance, can be determined using the formula c² = a² + b², where 'c' stands for the hypotenuse and 'a' and 'b' are the two legs.

Given,

Right angled triangle

Now,

To solve the system of equation,

Let us make the coefficient of x same in both the equations to eliminate x.

3x + 4y = 4

Multiply equation 1 with 3 and equation 2 with 2.

Answer:

4.6

Step-by-step explanation:

we can use the Pythagorean theorem of

A^2 + B^2 = C^2

where A and B are the (lengths of) short sides of a right triangle and C is the (length of) long side.

Here, we have an unknown side, let's call it X, and we know that:

2^2 + X^2 = 5^2

So

4 + X^2 = 25

X^2 = 25 - 4 = 21

X^2 = 21

X = [tex]\sqrt{21}[/tex]

Let's find the root of 21 rounded to the nearest tenth (or you can probably use a calculator, the method I show below is mathematically proper but not part of the curriculum).

the root of 21 is bigger than the root of 16 but smaller than the root of 25. So the number we're looking for is between 4 and 5.

21 is pretty much in the middle, so let's start by checking if it's bigger than 4.5

4.5^2 = 20.25

So 4.5 is a bit too small

Let's check 4.6

4.6^2 = 21.16

So 4.6 is a bit too big.

So we know our number is between 4.5 and 4.6 now. To have a good rounding to the nearest tenth, we only need to find out if it's over or below 4.55 (as this gives us direct rounding to the nearest tenth).

4.55^2 = 20.7025

So X is bigger than 4.55 and smaller than 4.6, hence the answer rounded to the nearest tenth is 4.6
