What are the coordinates of the vertex of the quadratic function having a minimum value of –1 and roots located at (–3, 0) and (–5, 0)?
plz help I'm really lost!

Answers

Answer:

The coordinates of the vertex will be (-4,-1)

Step-by-step explanation:

Let's recall that the vertex is in the middle point of the roots of a quadratic function.

The root are (-3,0) and (-5,0) so the x-value of the vertex will be:

[tex]x_{vertex}=\frac{-5-(-3)}{2}-3[/tex]

[tex]x_{vertex}=-1-3=-4[/tex]

The y-value of the vertex is given by the minimum value, that is -1

Therefore, the coordinates of the vertex will be (-4,-1)

The area of a circle is 132.7 square cm. Find the diameter.

Answers

13 cm (approximately)

Step-by-step explanation:

Let the radius of the circle be 'r'.

Area of the circle = πr²

=> 132.7 = (22/7) r²

=> 6.5 ≈ r

Therefore, diameter = 2radius = 2(6.5) = 13 cm

in a choir the ratio of men to woman is 4:7. 25% of the men prefer classical songs, and 80% of the women prefer classical songs. What percentage of the choir prefer classical songs?

Answers

Answer:

60%

Step-by-step explanation:

percentage of men in the choir = (4/11) x 100 = 36.4%

percentage of women in the choir = (7/11) x 100 = 63.6%

Percentage of men in the choir that prefer classical songs = 36.4 x0.25 = 9.1%

Percentage of women in the choir that prefer classical songs = 0.8 x 63.6% = 50.9%

percentage of the choir prefer classical songs = 50.9% + 9.1% = 60%

Question: Find the angle measures of the inscribed quadrilateral.

Answers

Answer:

[tex] m\angle A = 112 \degree [/tex]

[tex] m\angle B=95 \degree [/tex]

[tex] m\angle C =68 \degree [/tex]

[tex] m \angle D = 85 \degree [/tex]

Step-by-step explanation:

Quadrilateral ABCD is inscribed in a circle. So, ABCD is a cyclic Quadrilateral.

Opposite angles of cyclic quadrilateral are supplementary.

Therefore,

[tex]m\angle A + m\angle C = 180\degree \\ (14z - 7) \degree + (8z) \degree = 180 \degree \\ (14z - 7 + 8z) \degree= 180 \degree \\ (22z - 7) \degree= 180 \degree \\ 22z - 7 = 180 \\ 22z= 187 \\ z = \frac{187}{22} \\ z = 8.5 \\ \\ m\angle A = (14z - 7) \degree \\ = (14 \times 8.5 - 7) \degree \\ = (119 - 7) \degree \\ m\angle A = 112 \degree \\ \\ m\angle C =180 \degree - 112 \degree \\ m\angle C =68 \degree \\ \\ m \angle D = (10 \times 8.5) \degree \\ m \angle D = 85 \degree \\ \\ m\angle B =180 \degree - 85 \degree \\ m\angle B=95 \degree [/tex]

A drug company is considering marketing a new local anesthetic. The effective time of the anesthetic the drug company is currently producing has a normal distribution with an average of 7.4 minutes. The chemistry of the new anesthetic is such that the effective time should be normal with the same standard deviation, but the mean effective time may be lower. If it is lower, the drug company will market the new anesthetic; otherwise, they will continue to produce the older one. A hypothesis test will be done to help make the decision.

A sample of size 36 results in a sample mean of 7.1 and a sample std deviation of 1.2.

Complete the 5 step hypothesis test at significance level 0.10; make and support your decision.

Given:

The given degree measurement is -60 degrees.

To find:

The radian measure of the given degree measure.

Solution:

We know that,

[tex]\text{Radian measure}=\text{Degree measure}\times \dfrac{\pi}{180^\circ}[/tex]

The radian measure of -60 degrees.

[tex]\text{Radian measure}=-60^\circ \times \dfrac{\pi}{180^\circ}[/tex]

[tex]\text{Radian measure}=-\dfrac{\pi}{3}[/tex]

Therefore, the radian measure of the given degree measure is [tex]-\dfrac{\pi}{3}[/tex].
