Justin’s doctor said that the expression StartFraction x y 5 over 2 EndFraction, where x and y are his parents’ current heights
olya-2409 [2.1K]

He should have added the values in the numerator before dividing by 2.

<h2>Given </h2>

Justin’s doctor said that the expression;

Expression;\rm \dfrac{x+y+5}{2}

Where x and y are his parents’ current heights in inches.

Mom’s height = 54 inches Dad’s height = 71 inches.

Substitute all the values in the equation;

\rm= \dfrac{x+y+5}{2} =\\\\=\dfrac{71+54+5}{2} \\\\= \dfrac{130}{2}\\\\= 65

Hence, He should have added the values in the numerator before dividing by 2.

Need some help with trigonometry. Last question answered by bots.
Montano1993 [528]

Answer:

See below for answers and explanations

Step-by-step explanation:

<u>First, find the missing side using the Pythagorean Theorem:</u>

c²=a²+b²

65²=a²+16²

4225=a²+256

3969=a²

63=a

<u>Therefore:</u>

sinα = opposite/hypotenuse = 63/65

cosα = adjacent/hypotenuse = 16/65

tanα = opposite/adjacent = 63/16

sinβ = opposite/hypotenuse = 16/65

cosβ = adjacent/hypotenuse = 63/65

tanβ = opposite/adjacent = 16/63

Sophie [7]

Answer:

4.) Choice B

    &

5.) Choice A

Step-by-step explanation:

<em><u>Question 4:</u></em>

First you have to solve for y to get slope intercept form.

2x-5y=6\\5y=-2x+6\\y=-\frac{2}{5}x+\frac{6}{5}

The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.

<em><u>Question 5:</u></em>

For this one I we will use this formula m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

I will choose the easy pairs to plug it in (-12,-2) (20,6)

\frac{6--2}{20--12}\\\\\\\frac{8}{32}=\frac{1}{4}

The slope is a fraction again but you can convert it and that'll be Choice A.
