Step-by-step explanation:

CD = ED --- (secant property)

so, ==>>

13x - 16 = 4x + 11

13x - 4x = 11 + 16

9x = 27

x = 27÷9

x = 3

side ED = 4x + 11 = 4×3 + 11

side ED = 23

side FE = 12

ΔFED = 90° ...... (tangent secant property)

so.........

FE² + ED² = FD² ......... ( by pythagoras theorm)

12² + 23² = FD²

144 + 529 = FD²

673 = FD²

√673 = FD

26 = FD

Answer:

18in

Step-by-step explanation:

Given data

Height h= 15 in

Area= 135 in^2

The expression for the area is given as

Area= 1/2 Base * Height

substitute

135= 1/2* Base*15

135= 7.5 Base

Base= 135/7.5

Base=  18 in

Hence the base is 18in

Answer:

x = 1

y = 0

Step-by-step explanation:

3x - y = 3

2x - y = 2 , then y = 2x - 2

substitute for y:

3x - (2x - 2) = 3

combine like terms:

x + 2 = 3

subtract 2 from both sides of the equation:

x = 1

y = 2(1) - 2 = 0

Answer:

x=5, y=8

Step-by-step explanation:

let 3x-y=3 be [1]

and 2x-y = 2 be [2]

Change up [2] to:

2x=2+y

2x-2 = y and name this [3]

Sub [3] into [1]

3x-(2x-2)=3

3x-2x-2=3

x-2=3

x=5

Sub x=5 into [3]

2(5)-2=y

10-2=y

8=y

Answer:

[tex]\displaystyle y=\sin(x),\text{ where } 0\leq x\leq\pi/4[/tex]

Step-by-step explanation:

The curve passes through the point (x, y) = (0, 0) and has an arc length on the interval [0, π/4] given by the integral:

[tex]\displaystyle \int_{0}^{\pi/4}\sqrt{1+\cos^2(x)}\, dx[/tex]

And we want to find the equation of the curve.

Recall that arc length is given by:

[tex]\displaystyle L=\int_a^b\sqrt{1+\Big(\frac{dy}{dx}\Big)^2}\, dx[/tex]

Rewrite our original integral:

[tex]\displaystyle \int_{0}^{\pi/4}\sqrt{1+(\cos(x))^2}\, dx[/tex]

So:

[tex]\displaystyle \frac{dy}{dx}=\cos(x)[/tex]

It follows that:

[tex]\displaystyle y=\sin(x)+C[/tex]

Using the initial condition:

[tex]0=\sin(0)+C\Rightarrow 0=0+C\Rightarrow C=0[/tex]

The equation for our curve is:

[tex]\displaystyle y=\sin(x),\text{ where } 0\leq x\leq\pi/4[/tex]

Answer:

The area will be "34 unit²".

Step-by-step explanation:

The diagram is missing throughout the given question. Below is the figure attached.

According to the question,

The side of squares will be:

=  [tex]\sqrt{(5)^2+(3)^2}[/tex]

=  [tex]\sqrt{25+9}[/tex]

=  [tex]\sqrt{34} \ units[/tex]

Hence,

The area of square will be:

=  [tex](side)^2[/tex]

=  [tex](\sqrt{34} )^2[/tex]

=  [tex]34 \ unit^2[/tex]

Answer:

84 ounces of pure gold

Step-by-step explanation:

Jess has 60 ounces of an alloy that is 40% gold. How many ounces of pure gold must be added to this alloy to create a new alloy that is 75% gold?

Pure gold = 100% gold

Let the number of ounces of pure gold = x

Hence, we have the equation

40% × 60 ounces + 100%× x ounces = 75%(60 + x)ounces

= 0.4 × 60 + 1x = 0.75(60 + x)

= 24 + x = 45 + 0.75x

Collect like terms

x - 0.75x = 45 - 24

0.25x = 21

x = 21/0.25

x = 84 ounces

Therefore, we need 84 ounces of pure gold

84 ounces of pure gold must be added

The first is to write out the parameters

Jess has 60 ounces of alloy

40% of this alloy is pure gold

The number of ounces that should be added can be calculated as follows;

Let y represent the unknown

40/100(y)(60) + 100/100(y)= 75/100(60+y)

24 + y= 0.75(60+y)

25 + y= 45 + 0.75y

24 - 45= 0.75y -y

-21= -0.25y

y= 21/0.25

y= 84

Hence the number of ounces of pure gold required is 84 ounces

Answer:

Step-by-step explanation:

The sum of these adjacent angles must sum to 180 degrees (also the sum of all angles must be 360)

a+5a=180

6a=180

a=30

The larger angle is 5a so the larger angle is

5(30)=150 degrees.
