Define operation $\heartsuit$ so that \[ a \heartsuit b = \dfrac{a + b}{2}. \] Let $H$ be a function defined by \[H(x,y,z) = \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right). \] Write an expression for a simplified version of this function: $H(x,y,z) = \boxed{\phantom{blaaaaaaaaaa^2_2}}$ Write an expression, not an equation. Sample answer: $x + y + z$

Answers

Answer:

(-x+z)/4

Step-by-step explanation:

Evaluate the $\heartsuit$ operation to simplify.

\begin{align*}

H(x,y,z) &= \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right) \\

&= \left(\dfrac{x+y}{2}\right) \heartsuit z - x \heartsuit \left(\dfrac{y+z} 2\right) \\

&= \dfrac{\dfrac{x+y}{2} + z}{2}  - \dfrac{x + \dfrac{y+z}{2}}{2}

\end{align*}This looks ugly, but it works out! Continue by multiplying each fraction's numerator and denominator by $2$, in order to eliminate the complex fractions.

\begin{align*}

H(x,y,z) &= \dfrac{\dfrac{x+y}{2} + z}{2}  - \dfrac{x + \dfrac{y+z}{2}}{2} \\

&= \dfrac{x + y + 2z}{4} - \dfrac{2x + y + z}{4} \\

&= \dfrac{(x+y+2z) - (2x + y + z)}{4}

&= \dfrac{-x+z}{4}

\end{align*}Surprisingly it simplifies all the way down to $H(x,y,z) = \boxed{\dfrac{-x + z}{4}}$. The value of $y$ is not even used!

Can you find the PERIMETER of this shape pls ​

Answers

Answer:

25.7 m

Step-by-step explanation:

Hello!

We have two sides each measuring 5m, so the length of the straight edges is 2(5m) or 10m

We also have two identical semi-circle circumferences, so if we find the circumference of the whole circle, we can find the total length of the curved edges.

C = 2πrC = 2(3.14)(2.5)C = 5(3.14)C = 15.7

Now, we can add up the two lengths:

Perimeter = straight sides + curved sidesPerimeter = 10m + 15.7mPerimeter = 25.7m

Hunter kicked a soccer ball. The ball went 332 yards in 38 second. At that rate, how far would the ball go in 1 second?

Answers

The distance that he would the ball go in 1 second will be 8.8 yards.

How to calculate the rate?

From the information, Hunter kicked a soccer ball. The ball went 332 yards in 38 second.

Therefore, at that rate, the distance that he would the ball go in 1 second will be:

= Total distance / Time

= 332 / 38

Write an equation of a line that passes through the point (0,-2) and is perpendicular to the image shown.

options:

y= 3x −2

y= −1/3x − 2

y= 1/3x

y= 3x − 10

Answers

Answer:

Brainliest Answer would be appreciated. Option 1 is the best

Step-by-step explanation:

The slope of the line on the graph is -1/3. A perpendicular line's slope is always the negative reciprocal of it, so your slope of the perpendicular line would be 3.

Also, since you are passing through the point (0, -2), -2 would be your y-intercept, making your equation for the perpendicular line y = 3x - 2.

find the simple intrest on rs 1200 at 5%per annum for 2 years

Answers

Answer:

Rs.120

Step-by-step explanation:

given,

Principal (P) = Rs.1200

Time (T) = 2 yrs

Rate (R) = 5%

Simple interest = ?

solution,

simple interest = PTR/100

= Rs.1200*2*5/100

= Rs.12000/100

= Rs.120

Therefore,the simple interest is Rs.120.

We need to find the positive difference in their x coordinates and y coordinates.

The difference in x coordinates: 7

The difference in y coordinates: 8

Now we can use the Pythagorean theorem:

49+64 = x^2

113 = x^2

x = sqrt(113)

Which of the following is the measure of the largest angle in the triangle shown?

Answers

36x = 180

x = 5°

largest angle = 19 * 5 = 95°

Answer:

C. 95°

Step-by-step explanation:

19x+ 7x +10x = 180 (sum of the interior angles of a triangle is 180)

36x = 180

x= 180÷36

x= 5

Magnitude of the largest angle
