Answer:

50 cm² and 56 cm²

Step-by-step explanation:

The area (A) is calculated as

A = $\frac{1}{2}$ × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )

(2)

A = $\frac{1}{2}$ × (8 + 2) × (5 + 5)

= 0.5 × 10 × 10

= 5 × 10

= 50 cm²

(3)

A = $\frac{1}{2}$ × (12 + 2) × (4 + 4)

= 0.5 × 14 × 8

= 7 × 8

= 56 cm²

If g is the midpoint of FH and FH =6y-2 find y

miss Akunina [59]

Answer:

y=8

Step-by-step explanation:

see the attached figure to better understand the problem

we have that

FH=FG+GH

FG=GH

step 1

Find the value of x

FG=GH

substitute the given values

4x+3=7x-12

solve for x

$7x-4x=12+3\\3x=15\\x=5$

step 2

Find the value of y

FH=FG+GH

substitute the values

$6y-2=(4x+3)+(7x-12)6y-2=(4(5)+3)+(7(5)-12)6y-2=23+23\\6y-2=46\\6y=46+2\\6y=48\\y=8$

Which function below is the inverse of f(x) = x2 − 36?. . x squared over 36. . ±6square root of x. . 1 over quantity x squared m

tatiyna

The function is f(x) = x^2 - 36. => y = x^2 - 36. To find the inverse function, you can exchange the variables (x,y) and the solve for the new y => x = y^2 - 36 => y^2 = x + 36 => <span>y = +/- sqrt of x + 36. So, the answer is +/- square root of the quantity x plus 36</span>

Choose the fraction that has not been reduced to simplest form.

Gennadij [26K]

We are required to choose the fraction that has not been reduced to simplest form

The fraction that has not been reduced to simplest form is 19/38 and 10/18

1. 21 / 34 is in its simplest form

factors of 21 = 1, 7 and 21

factors of 34 = 1, 2, 17 and 34

No common factor of 21 and 34 except 1

2. 15/16

factors of 15 = 1, 3, 5, 15

Factors of 16 = 1, 2, 4, 8 and 16

No common factor of 15 and 16 except 1

3. 19/38

factors of 19 = 1, 19

factors of 38 = 1, 2, 19 and 38

divide both numerator and denominator by 19

So,

19 / 38 = 1/2

4. 10/18

factors of 10 = 1, 2, 5 and 10

factors of 18 = 1, 2, 3, 6, 9 and 18

So,

10/18

divide both numerator and denominator by 2

= 5/9

slamgirl [31]

The given question have mistake. The correct question is written below.

Question:

A dog jumps straight up in the air to catch a ball and lands on the ground 6.37 s later. Let h(t) represent the dog’s height, in meters, t seconds after he leaves the ground. Which equation models the dog’s height for a given time t?

Answer:

Option B:

$h(t)=-4.9 t^{2}+6.37t$

Solution:

<u>General formula for the height of the projectile over time:</u>

(1) $h(t)=-16 t^{2}+v t+s$

Where h = height in feet, t = time, v = initial velocity and s = initial height (feet)

(2) $h(t)=-4.9 t^{2}+v t+s$

Where h = height in meters, t = time, v = initial velocity and s = initial height(meter)

Given initial velocity = 6.37 s and initial height is 0.

The height of the dog is in meters.

So, use second formula and substitute v = 6.37 and s = 0.

$h(t)=-4.9 t^{2}+v t+s$

$h(t)=-4.9 t^{2}+6.37t+0$

$h(t)=-4.9 t^{2}+6.37t$

Hence option B is the correct answer.

larisa [96]

Answer:

The Cholula Pyramid has a bigger volume out of the two.

Step-by-step explanation:

The volume of a Pyramid is V=1/3Bh

Volume of the Choulula = 1/3 (2,178,576)(217)= 157,583,664

Volume of The Cheops Pyramid = 1/3 (570,025)(480)=91,204,000

157,583,664 is greater than 91,204,000
