Answer:

Options C and D

Step-by-step explanation:

From the graph attached,

Coordinates of the vertices,

X → (0, 0)

Y → (-1, -2)

Z → (0, -2)

Rule for the rotation of a  point (h, k) by 180° about the origin is given by,

(h, k) → (-h, -k)

By this rule,

Coordinates of the image points will be,

X(0, 0) → X'(0, 0)

Y(-1, -2) → Y'(1, 2)

Z(0, -2) → Z'(0, 2)

Therefore, Option (C) and Option (D) are the correct options.

Answer

C/D

Step-by-step explanation:

Answer: The percent of red lights last between  2.5 and 3.5 minutes = 95.44% approx.

Step-by-step explanation:

Given: Mean time = 3 minutes

standard deviation = 0.25 minutes

The probability of red lights last between  2.5 and 3.5 minutes :-

[tex]P(2.5<x<3.5)\\\\=P(\dfrac{2.5-3}{0.25}<\dfrac{x-\mu}{\sigma}<\dfrac{3.5-3}{0.25})\\\\=P(-2<z<2)\\\\=2P(Z<2)-1\\\\=2(0.9772)-1\\\\=0.9544[/tex]

The percent of red lights last between  2.5 and 3.5 minutes = 95.44% approx.

4 right angles

90 + 90 + 90 + 90 = 360

However, it that figure is a circle-- it may include 0 right angles since circles have no angles.

Answer:

841.6 ft

Step-by-step explanation:

Solve this using the quadratic formula.

y=-16x^2+212x+139 becomes -16x^2 + 212x + 139.  The x-value of the axis of symmetry is

       -212

x = ----------- = 6.625  (This time measurement is in seconds.)

       2(-16)

The maximum height reached by the rocket is the y value when x = 6.625 and is y(6.625) = 841.6 ft

Given:

The quadratic equation is :

[tex]16x^2-20x-6=0[/tex]

To find:

The quadratic formula for the given equation after substituting the values.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]16x^2-20x-6=0[/tex]

In this equation, [tex]a=16,b=-20,c=-6[/tex].

Substituting [tex]a=16,b=-20,c=-6[/tex] in the above formula, we get

[tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex]

Therefore, the required quadratic formula for the given equation after substituting the values is [tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex].

Answer:

The answer is 2/7.

Step-by-step explanation:

If you flip a coin 7 times then 7 is the denominator, which stands for the total amount of times you flipped the coin. The numerator is 2, which is the amount of times you land on the same thing, in this case, landing on tails.

Answer:

10% of espressos sold are single shot espressos.

Step-by-step explanation:

Single shot espressos, as percentage of total espressos sold =

[ Single espressos / Total ( ie Single + Double shot) ] x 100

[ 2 / (2 + 18) ] x 100

(2 / 20) x 100

= 10%

Answer:

$87.12

Step-by-step explanation:

To mark up the price you are basically doing 45.85×190%.

If you take a percentage and make it a normal number you need to divide by 100.

190÷100= 1.9

So you multiply 45.85×1.9=87.115

Because this is money you cant have $87 and 11 and a half cents. So you need to round

You need to round up because it is 5, which means that you get $87.12

Hope this helped.

Answer:

49.5 ounces the flower

3 pounds, 1.5 ounces

Step-by-step explanation:

Given that :

24 cupcakes 9 ounces of flower

Number of ounces of flower required for 132 cupcakes will be x

Using cross multiplication method :

24 cupcakes = 9 ounces

132 cupcakes = x ounces

Cross multiply :

24 * x = 132 * 9

24x = 1188

divide both sides by 24 to isolate x

x = 49.5

Hence, 49.5 ounces the flower is required for 132 cupcakes

To express in pounds :

1 pound = 16 ounces

49.5 ounces = 3 pounds 1.5 ounces

Answer:

Yes

Step-by-step explanation:

If a triangle follows the Pythagorean theorem, then it is right. The Pythagorean theorem states the following,

[tex]a^2 + b^2 = c^2[/tex]

Where (a) and (b) are the legs or sides adjacent to the right angle of the right triangle, and (c) is the hypotenuse, side opposite the right angle, the longest side.

Substitute in the given values and solve,

[tex](6)^2 + (8)^2 = (10)^2\\\\36 + 64 = 100\\\\100 = 100[/tex]

The given side lengths form a right triangle.

Answer:

x = 53

Step-by-step explanation:

x = 53 because they are alternate exterior angles

Answer:

Subtract 22 from both sides of the equation.

x=-2

Answer:

x = -2

Just move the 2 to the other side. Remember to switch the sign.

Answer:

The answer that is not true when x = -4 is B.

Step-by-step explanation:

Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.

A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.

Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.

Finally D. -4/4 divided equals -1, so that would make it -1 = -1.

B is the only one that doesn't make sense, therefore you have your answer.
