Answer:

I'm pretty sure the answer is 6½

Answer:

13cm

Step-by-step explanation:

In this case you have to use the Pythagorean theorem.

cy = 24/2

cy=12 cm ( a perpendicular drawn to a chord from the center bisects the chord..

ac=5 cm (given)

now,

ay^2= 25cm + 144 cm

ay^2 = 169 cm

√169 = 13 cm

Answer:

13 cm

Step-by-step explanation:

Since AC is perpendicular to XY , and XA and AY are both radii of the same circle, you can say that AC is a perpendicular bisector.

From there, we can say that XC is 1/2 of 24 cm, or 12 cm.

We can then form triangle ACX use the Pythagorean theorem to find the length of AX.

The square root of 12^2 + 5^2 is 13.

Therefore, the radius of the circle is 13 cm

Answer:

-3x(2x+1)(3x-4)

Step-by-step explanation:

Add and subtract the second term to the expression and factor by grouping.

Anser and Explanation:

First, factor out an x to get:

[tex]x(-18x^2 + 15x + 12)[/tex]

Then, factor out a -3:

[tex]-3x(6x^2 - 5x - 4)[/tex]

Finally, factor by grouping:

[tex]-3x(6x^2 + 3x - 8x - 4)[/tex]

[tex]-3x(3x(2x + 1) - 4(2x + 1))[/tex]

[tex]-3x(3x - 4)(2x + 1)[/tex]

so -3x(3x - 4)(2x + 1) is the factored expression.

[tex]x^2+y^2=r^2~\hfill x=rcos(\theta )~\hfill y=rsin(\theta ) \\\\[-0.35em] ~\dotfill\\\\ r=3sin(A)\implies \stackrel{\textit{multiplying both sides by "r"}}{r^2~~ = ~~3~rsin(A)}\implies x^2+y^2=3y[/tex]

r = 3sinA is written in rectangular form as[tex]x^2+y^2 = 3y.[/tex]

Any complex number z = a + ib can be written in polar form as:

[tex]z = r(\cos(\theta) + i\sin(\theta))[/tex]

Complex numbers are those numbers that contain the imaginary and the real part.

Raising this to nth power (n being an integer), we get:

[tex]z ^n = r^n (\cos(n\theta) + i\sin(n\theta))[/tex]

We need to find r = 3sinA is written in rectangular form as[tex]x^2+y^2[/tex].

We know that

x = r cosA

y = r sin A

We have been given ;

r = 3sinA

Multiply by r on both sides;

[tex]r^2 = 3r sin A\\\\r^2 = 3 y[/tex]

therefore,

[tex]x^2+y^2 = 3y[/tex]

Hence, r = 3sinA is written in rectangular form as [tex]x^2+y^2 = 3y[/tex].

The coordinates of the vertices A'B'C when ABC is dilated by a scale factor of 1/6 are 1/6(x,y)

The rule of transformation is given as:

Dilation by a scale factor of 1/6

Mathematically, this is represented as:

(x,y) => 1/6(x,y)

This means that the coordinates of the vertices ABC are multiplied by 1/6 to get the coordinates of the vertices A'B'C

Answer:

x = 41

Step-by-step explanation:

Answer:

60 degrees

Step-by-step explanation:

any closed shape has a sum of 360 degrees, now if you subtract 150 from 360 it gives you 210 minus 90 degrees, it would equal to 120. Now 120 divided by 2 since we still need to find the other two corners we haven't found, that would equal to 60 degrees.

Answer:

Step-by-step explanation:

Given, The length of a rectangle is 4 ft less than three times the width, and the area of the rectangle is 55 ft².

Let's assume width of rectangle be x feet and length be 3x - 4 feet. Using the formula of Area of rectangle we'll find the value of length and width.

[tex] \\ \dashrightarrow{ \red{ \underline{ \underline {\sf\: \:Area _{(rectangle)} = Length \times width}}}} \\ \\ [/tex]

Substituting the required values:

[tex]\dashrightarrow\: \: (3x - 4)(x) = 55 \\ [/tex]

[tex]\dashrightarrow\: \: 3x^2 - 4x = 55 \\ [/tex]

[tex]\dashrightarrow\: \: 3x^2 - 4x - 55 = 0 \\ [/tex]

[tex]\dashrightarrow\: \: 3x^2 + 11x - 15x - 55 = 0 \\ [/tex]

[tex]\dashrightarrow\: \: x(3x+11) -5(3x+11) = 0 \\ [/tex]

[tex]\dashrightarrow\: \: (x-5)(3x+11) = 0 \\ [/tex]

[tex] { \red{ \dashrightarrow\: \: { \underline{ \underline{ {x = 5 \: or \: \dfrac{-11}{3}}}}}}} \\ \\ [/tex]

[tex]\therefore[/tex] The required dimensions of rectangle are 11 feet and 5 feet.

Answer:

-2

Step-by-step explanation:

Apply the rule for this:

a - (- b) = a + b

Thus, we have:

-14 - (-12) = -14 + 12

Add the number:

Since there are more negative than positive the final solution is negative

Hence, now 14 - 12 = 2

Now bring the negative down:

-2

Therefore, the answer is -2

When there are two minuses beside each other

⇒ we can equate them as a '+'

Area of the yellow sector is 58.91 cm2

The spinner has a circular shape and would be solved as a circle.

Area of a circle = pi r^2
