Answer:

A, E

Step-by-step explanation:

x + 6 = 5+x can not be a solution. This is because both of the x's will cancel each other out.

5 - 3x = -3x +4 can not be a solution. The negative 3x's will cancel each other out if you try to balance both sides by doing +3x on both sides.

The circumference of the circle is 762π cm.

The length of arc a circle can is determined with the radius and central angle of the arc.

The radius of the circle is calculated as follows;

[tex]L = \pi r \times \frac{ \theta }{180} \\\\ \pi r \theta = 180 L\\\\ \pi r = \frac{180 L}{\theta} [/tex]

The circumference of the circle is calculated as follows;

[tex]C = 2\pi r\\\\ C = 2(\pi r)\\\\ C = 2(\frac{180 \ L}{\theta } )\\\\ C = 2(\frac{180 \times 127\pi}{60 } )\\\\ C = 762 \pi \ cm[/tex]

The sum of the infinite geometric series is -288.

A finite geometric series with n = 4, a₁ = -144, and r = ½.

What is the sum of the infinite geometric series?

The sum of the infinite is determined by the following formula;

[tex]\rm S_\infty = \dfrac{a_1(1-r^n)}{1-r}[/tex]

A finite geometric series with n = 4, a₁ = -144, and r = ½.

Substitute all the values in the formula;

[tex]\rm \rm S_\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\ S\infty = \dfrac{-144(1-\dfrac{1}{2}^{4})}{1-\dfrac{1}{2}}\\\\ \rm S_\infty = \dfrac{-144 \times \dfrac{15}{16}}{\dfrac{1}{2}}\\\\ \rm S_\infty = -270[/tex]

Therefore,

The sum of the infinite geometric series is,

[tex]\rm S = \dfrac{a_1}{1-r}\\ \\ S = \dfrac{-144}{1-\dfrac{1}{2}}\\ \\ S = \dfrac{-144}{0.5}\\ \\ S = -288[/tex]

Hence, the sum of the infinite geometric series is -288.

The inequality that best describes the width of the garden is

Width ≤ 6 yards

Area ≤ Length* Width

Length = 5 yards

Width = ??

Area = 30 square yards

From the formula of the area of rectangle we have

Area = Length * Width

Let the width be x

Substitute

30 = 5 * x

30 = 5x

Divide both sides by 5

x = 30/5

x = 6 yards

Hence the with should be less than or equal to 6 yards

Step-by-step explanation:

We are supposed to replace 'x' with 1 and then evaluate.

=====================================================

[tex]f(x) = 10x + 45\\\rule{150}{0.5}\\f(1) = 10(1) + 45\\\\f(1) = 10 + 45\\\\\boxed{f(1) = 55}[/tex]

Hope this helps!

Answer:

Step 1  

Substitute f of x with y.

f of x equals x squared. y equals x squared.  

Step 2  

Switch the x and y variables.

y equals x squared. x equals y squared.  

Step 3  

Solve for y.

x equals y squared. Square root x equals square root y squared. Don’t forget, when taking the square root of a number or variable, both positive and negative values must be taken into consideration. Plus and minus square root x equals y.  

Step 4  

Replace y with f inverse x.

Plus and minus square root x equals y. Plus and minus square root x equals f inverse x.

Step 5  

Graph the inverse.

A graph of y equals plus and minus square root x. It is a left opening parabola with vertex at point 0 comma 0. If a vertical line were dragged across the graph, that line would cross the graph of y equals plus and minus square root x in more than one place. Therefore, the equation is not a function.

Answer:

b = 0

Step-by-step explanation:

Since,the equations y=3/4x+1 and y=1/2x+b intersect at (4,2)

So, plug x = 4 and y = 2 in equation y=1/2x+b, we find:

The unknown values are as follows:

a = 48.7°

b = 51.43

c = 12.16

d = 122.39

Therefore,

sin 72.3° = opposite / hypotenuse

sin72.3° = 49 / b

b = 49 / sin 72.3

b = 49 / 0.95266148125

b = 51.4348495916

b = 51. 43

a = (180 - 90 - 23.6) - (180 - 72.3 - 90)

a = 66.4 - 17.7

a = 48.7°

tan 23.6 = opposite /adjacent

tan 23.6 = 49 / c

c = 49 / tan 23.6

c = 112.158945248

c = 12.16

sin 23.6 = opposite /hypotenuse

sin 23.6 = 49 / d

d = 49 / sin 23.6

d = 49 / 0.40034903255

[tex]angle \: sum \: property \: of \: a \: triangle \\ states \: that \: the \: sum \: of \\ all \: the \: three \: angles \: of \: a \: triangle \: is \\ equal \: to \: 180°[/tex]

therefore~

[tex]63 + (x + 17) + (4x - 5) = 180° \\ 63 + x + 17 + 4x - 5 = 180° \\ 5x + 75 = 180 \\ 5x = 180° - 75 \\ 5x = 105° \\ x = \frac{105}{5} = 21°[/tex]

therefore the measure of all the angles are..

∠1 = 63°

∠2 = ( x + 17 ) = ( 21 + 17 ) = 38°

∠3 = ( 4x - 5 ) = ( 84 - 5 ) = 79°
