Answer:

angles of half a circle is 90

its 90 degrees

Answer:

90°

Step-by-step explanation:

the triangle is inside a circle and  touches the circle with each vertex and one of the side of the triangle is diameter of the circle. then the triangle is right triangle

Hey there! I'm happy to help!

First, we'll want to find the vertex of this parabola.

Given the equation y=ax^2+bx+c, the formula for the x-coordinate of the vertex is always [tex]-\frac{b}{2a}[/tex].

In our equation here, our a is 1 and our b is -2.

[tex]-\frac{-2}{2}=\frac{2}{2}=1[/tex]

Now that we have our x-value of our vertex, we can plug it into our equation to find our y-coordinate.

y=1²-2(1)-5

y=1-2+5

y=-1+5

y=4

So, our vertex is at (1,4).

Vertex form is y=a(x-h)²+ k where (h,k) is our vertex. We know now that our vertex is (1,4) and we also know that our a is 1, so we can simply plug it in to this equation.

y=(x-1)²+4

Have a wonderful day and keep on learning! :D

According to the figure:-

We know that Sin∅=P/H

Hence Sinx°=13/25

Answer:

x=9 y=12

Step-by-step explanation:

eqn 1 - x=2y-15

eqn 2- -5x+4y=3

-5(2y-15)+4y=3

-10y+75+4y-3=0

-6y+72=0

y= 12

x=2y-15

x=2(12)-15

x= 9

Hey man, refer the attachment.

Answer:

-2 1/3, 1/16, √15, 4^2

Following order from least to greatest.

Answer:

see explanation

Step-by-step explanation:

Complementary angles sum to 90° , then

5x + 7 + 8x - 21 = 90 , that is

13x - 14 = 90 ( add 14 to both sides )

13x = 104 ( divide both sides by 13 )

x = 8

Then the measure of the angles are

5x + 7 = 5(8) + 7 = 40 + 7 = 47°

8x - 21 = 8(8) - 21 = 64 - 21 = 43°

--------------------------------------------------------

let the angle be x then its complement is (90 - x) and

x = 2(90 - x) + 21

x = 180 - 2x + 21

x = 201 - 2x ( add 2x to both sides )

3x = 201 ( divide both sides by 3 )

x = 67

The measure of the angle is 67°

Answer:

-4x + 5y

Step-by-step explanation:

-1/6 x 24 x simplifies to -1 times 4x, which is -4x.  -1/6 times -30y simplifies to -1 times -5y, which is 5y.

Hi

let's call X number of photo ordered.

So total Cost  is  C(x) = 7X+ 25

Il let you calculate for X = 12 . Have fun

Answer:

First, let us prime factorise the given number

3993 = 3×11×11×11

Check for numbers in triplets. We find that only 11 is occuring as a triplet. Hence we must eliminate the three.

So if we divide 3993 by 3, we'll get a perfect cube, that is 1331 (11³)

So, the answer is 3

Answer:

cos6x.

Step-by-step explanation:

We use the identity

cosAcosB - sinAsinB = cos(A+B)

so cos5xcosx - sin5xsinx = cos(5x + x)

= cos6x.

Answer:

w = 6.

Step-by-step explanation:

5w + 3 = 4w + 9

5w - 4w = 9 - 3

w = 6

Then, check your work!

5(6) + 3 = 4(6) + 9

30 + 3 = 24 + 9

33 = 33

So, w = 6 will be the correct answer.

Hope this helps!

Answer:

3

Step-by-step explanation:

Answer:

Step-by-step explanation:

1 cup = 8 fl oz

x cup = 6 fl oz                         Cross multiply

6 oz * 1 cup = 8 oz x               divide by 8

x = 6 oz /8 oz = 3/4 cup

If kim needs 1/4 cup per batch then she will have enough for 3 batches of 1/4 cup each.

Answer:

The average speed of A is

100m ÷ 10. 93s = 9.14m/s

The average speed of B is

100m ÷ 10. 49s = 9. 53m/s

The average speed that B is faster than A is 9. 53 - 9. 14 = 0. 42m/s

The speed that B is faster than A is

0. 42m/s × 10. 49s = 4. 40m

So, B won by 4. 40m

Answer

you cant have a remainder bigger then your divident

Step-by-step explanation:

Answer:

The Lowest common multiple of 25, 30 and 75 is 150.

Answer:

Step-by-step explanation:

The first thing should always do is find a program that will show you what the graph looks like. Desmos is a free program that suits all graphing questions.

That will give you the answer (which I have labeled for you.)

First make x = 0

That gives you y = 0 + 4 = 4

The point is (0,4)

Now let y = 0

0 = -1/5 x + 4     Add 1/5x  to both sides

1/5 x = 4             Now multiply by 5

x = 5*4

x = 20

The point is (20,0)

You need one more point just to confirm your work. I chose x = - 5

When you do the calculation it comes out to y = 5

The point is (-5,5) which is labeled.

3x²

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 3x - (- 3x² + 3x) ← distribute parenthesis by - 1

= 3x + 3x² - 3x ← collect like terms

Answer:

135 tickets

Step-by-step explanation:

Vie's brother sold twice as many as Vie. So we multiply Vie's tickets by 2 to get the brother's.

VIe's brother sold 45 * 2 = 90 tickets

And all together the two sold

45 + 90 = 135 tickets

First find Divisor

[tex]\\ \sf\longmapsto x^2-(-3-2)+(-3)(-2)[/tex]

[tex]\\ \sf\longmapsto x^2+5x+6[/tex]

Dividend given by

[tex]\\ \sf\longmapsto x^4-x^3-16x^2+4x+48[/tex]

We know

[tex]\boxed{\sf Dividend=Divisor\times Quotient +Remainder}[/tex]

[tex]\\ \sf\longmapsto Dividend=Divisor\times Quotient[/tex]

[tex]\\ \sf\longmapsto Quotient=\dfrac{Dividend}{Divisor}[/tex]

[tex]\\ \sf\longmapsto \dfrac{x^4-x^3-16x^2+4x+48}{x^2+5x+6}[/tex]

[tex]\\ \sf\longmapsto x^2-6x+8[/tex]

Now factor

[tex]\\ \sf\longmapsto x^2-6x+8=0[/tex]

[tex]\\ \sf\longmapsto x^2-4x-2x+8=0[/tex]

[tex]\\ \sf\longmapsto x(x-4)-2(x-4)=0[/tex]

[tex]\\ \sf\longmapsto (x-4)(x-2)=0[/tex]

[tex]\\ \sf\longmapsto x-4=0\:or\:x-2=0[/tex]

[tex]\\ \sf\longmapsto x=4\:or\:x=2[/tex]

Hence all zeros are

Answer:

35 different combinations

Step-by-step explanation:

This would be a combination because the same person cannot get all three medals so permutation is not the correct way to calculate this. We use the formula C(n,r)=(nr)=n!(r!(n−r)!)=? where n is the number of total objects and r is the number of objects taken from the total.
