When a coordinate is reflected across the y axis, the x changes to the opposite and y stays the same.

X(0, -6) X' (0,-6)

Y(-10, 4) Y'(10, 4)

Z(3, -1) Z' (-3,-1)

Hopes this helped!!!!

Cos B = tan B = sin B =

Oduvanchick [21]

The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).

Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse

Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse

Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.

The acronym to remember this is SOHCAHTOA

SOH | CAH | TOA

SOH means sin(x) = opposite/hypotenuse

CAH means cos(x) = adjacent/hypotenuse

TOA means tan(x)= opposite/adjacent

cosB = length of adjacent side/length of hypotenuse = 7/25

tanB = length of opposite/length of adjacent = 24/7

sinB = length of opposite/length of hypotenuse = 24/25

Answer:

The 95% confidence interval is ( 27.126 , 34.674)

Step-by-step explanation:

Given

The t critical value at 0.05 level = 2.023 for the df = 39

Confidence interval = 95%

Mean

$\bar{x} - t * \frac{s}{\sqrt{n} } < \mu < \bar{x} + t * \frac{s}{\sqrt{n} }$

Substituting the given values we get -

$\30.9 - 2.023 * \frac{11.8}{\sqrt{40} } < \mu < \30.9 + 2.023 * \frac{11.8}{\sqrt{40} }\\27.126 < \mu < 34.674$

Hence, the 95% confidence interval is

( 27.126 , 34.674)

Jordan spent 22% of his time doing math homework. If hw spent 11 minutes on his math homework. How many minutes did he spend on

devlian [24]

Answer:

The total minutes he spend on his homework are 50 minutes.

Step-by-step explanation:

It is given that Jordan spent 22% of his time for homework on maths.

It is also given that he spent 11 minutes of time on maths homework.

The above two statements are equal.

Let the total time for homework be "x".

Thus, the equation can be written as,

$(\frac{22}{100})(x) = 11$

$x = (\frac{100}{22})(11) = 50 minutes$

Thus the total minutes he spend on his homework are 50 minutes.
