Answer:

Step-by-step explanation:

Use the vertex form, y=a(x−h)2+k y = a ( x - h ) 2 + k , to determine the values of a a , h h , and k k . a=−112 a = - 1 12. h=3 h = 3. k=−2 k = - 2.

Answer:

You flip a coin 4 times, with 2 possibilities every flip, heads or tails. So, every time you throw there's a 50% chance you'll throw tails. so it would be 1/2

The probability of getting at least 2 tails is 0.688.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes

Given that, a fair coin is tossed 4 times.

So, sample space is

S = {HHHH, TTTT, HHHT, HHTH, HTHH, THHH, HHTT, HTTH, HTHT, THHT, THTH, TTHH, HTTT, THTT, TTHT, TTTH}

Now, total number of outcomes =16

Number of favorable outcomes = 11

Probability =11/16

= 0.6875

≈ 0.688

Therefore, the probability of an event is 0.688.

Answer:

y = 43 and x = 90

Step-by-step explanation:

We know that a triangle is 180 degrees (each side equals 180 since they are their own triangles) We will focus on the left triangle. Since x is a right angle, it is 90 degrees. Since there is a slash across the two sides of the main triangle, that means both sides are equal. This means that the bottom left angle, the one above b, is equal to 47 degrees. That means we know two angles out of 3. For the sake of simplicity, the bottom left angle, the one above b, is point z. So point z is 47, and x is 90, added they are 137. Subtract that from 180, you will get 43. 43 is y.

Answer:

x = 6

Step-by-step explanation:

-2 + 3x = 16

add 2 to both sides

-2 + 2 + 3x = 16 + 2

0 + 3x = 18

3x = 18

divide both sides by 3

3x ÷ 3 = 18 ÷ 3

1x = 6

x = 6

Answer:

6

Step-by-step explanation:

To solve this we must get the variable and the number alone on one side.

Answer:

494.4 inches²

Step-by-step explanation:

we can see that there are four quarter circles inscribed in the square. 4 quarters make up a whole so all we need to find is the area of the square minus the area of the large circle. area of a circle is πr²

area of the circle: (24)²×π=1809.557

area of the square: (24×2)²=2304

shaded area: 2304-1809.557=494.443 which rounds down to 494.4

Answer:

Slope can be found by determining the ratio of the rise (vertical change) to the run (horizontal change).

In this case miles is the rise, and 3 hours is the run

It should rise 12 and go over 3

I cannot really make out what's on your screen but it's likely it would be D.

The line has to pass 3, it cannot be off 3 by a bit.

And it should be lower than 20 because it rises 12.

Answer:

$21.60

Step-by-step explanation:

20% can be written as 0.2

0.2 · $18 = 3.6

Add 3.6 to $18

$18.00 + 3.60 = $21.60

So the answer is $21.60

Step-by-step explanation:

using the sine ratio in the right triangle

sin20° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{11.9}{c}[/tex] ( multiply both sides by c )

c × sin20° = 11.9 ( divide both sides by sin20° )

Answer:

[tex] x = \frac{1}{64} [/tex]

Step-by-step explanation:

[tex] \frac{4x}{1} = \frac{1}{16} [/tex]

Then you CROSS MULTIPLY.

WHICH IS.

4x × 16 = 1

64x = 1

Then you divide both sides by coefficient of x which is 64.

[tex] \frac{64x}{64} = \frac{1}{64} [/tex]

x = 1/64

Answer:

The statements are not given, so i will answer it in the most general way possible:

First, let's recall two things:

Horizontal translation.

For a number A positive, we can move the graph of f(x) by A units to the right by the transformation g(x) = f(x - A)

Reflection over x

For a point (x, y), a reflection over the x-axis transforms this point into (x, - y).

Now let's analyze the problem:

A generic circle, of radius R and centered in the point (a, b) can be written as:

(x - a)^2 + (y - b)^2 = R^2.

Now let's translate this 4 units to the right:

(x - 4 - a)^2 + (y - b)^2 = R^2.

or in standard circle notation:

(x - (4 + a))^2 + (y - b)^2 = R^2.

Now the circle is centered in the point (a + 4, b).

Now let's do a reflection over the x-axis.

This means that the sign of y changes, so now we have:

(x - (4 + a))^2 + (-y - b)^2 = R^2.

But because the term with y is squared, this is the same than:

(x - (4 + a))^2 + (y + b)^2 = R^2.

Or, in standard circle notation:

(x - (4 + a))^2 + (y - (-b))^2 = R^2.

Then the circle is now centered in point (a + 4, -b).

So now you know where the circle is located, and also you can see that the radius of the circle never changed.

Answer:

Independent

Step-by-step explanation:

Ok so the general form of a circle is given by;

(x-a)²+(y-b)²=r²

where a and b are the coordinates of the center

and r is the radius of the circle

For this case we know that the center is (5,-7)

So the general equation of the circle would be;

[tex](x - 5) {}^{2} + (y - ( - 7)) {}^{2} = r {}^{2} [/tex]

[tex](x - 5 {}^{2} + (y + 7) {}^{2} = r {}^{2} [/tex]

Since we know that (-3,-1) is a point on that circle, we can say that it satisfies the equation of the circle;

[tex]( - 3 - 5) {}^{2} + ( - 1 + 7) {}^{2} = r {}^{2} [/tex]

[tex]r {}^{2} = ( - 8) {}^{2} + ( 6) {}^{2} [/tex]

[tex]r {}^{2} = 64 + 36 = 100[/tex]

So now,

[tex](x - 5) {}^{2} + ( {y + 7)}^{2} = 100[/tex]
