On a piece of paper,graph y+4

1 answer:

6 0

Well right now you have a linear function with 0 as a slope. The equation now is y+4=0 but in order to graph this, you subtract 4 to the right side to get the equation y= -4. This is now just a horizontal line extending in either direction on the grid where 4 is on the y axis.

Is a diameter of 9cm more than a radius of 5cm and which would have the larger circumference?

Tpy6a [65]

Answer:

Circle B

3.14 cm

Step-by-step explanation:

1. The diameter is twice the radius, so the diameter of Circle B is ...

2 × 5 cm = 10 cm

This diameter is greater than the 9 cm diameter of Circle A, so Circle B is larger and will have a larger circumference.

2. The circumference is the product of π and the diameter. Then the difference between the two circumferences is ...

... (circle B circumference) - (circle A circumference) = π·(10 cm) - π·(9 cm)

... = π·(10 -9) cm = π·1 cm ≈ 3.14 cm

I need help with #39-42, please explain.

shusha [124]

For question 39 & 40, we need to use the below equation to complete the sentence

$l=m\sqrt{n}$

Question 39:

When ' n ' increase, the $\sqrt{n}$ will also increase and that multiplied with constant ' m ', the l will also increase.

Solution for question 39:

As $n$ increases and $m$ stays constant , $l$ increases

-------

Question 40:

Solving the equation for m, we get

$l = m\sqrt{n} \\ \\ m=\frac{l}{\sqrt{n}}$

When ' l ' increases, the numerator increase, the denominator stays constant because 'n' stays constant, for this condition, the fraction increases.

Solution for question 40:

As $l$ increase and $n$ stays constant, $m$ increases

------

For question 41 & 42, we need to use the below equation to complete the sentence

$r=s^2/t^2$

Question 41:

When $s$ is triped, the equation will be...

$r=(3s)^2/t^2=\frac{3^{2}s^{2}}{t^2} =9s^2/t^2$

Solution for question 41:

If $s$ is tripled and $t$ stays constant, $r$ is multiplied by 9

--------

Question 42:

When t is doubled, the equation will be...

$r=s^2/(2t)^2=\frac{s^2}{2^2 \cdot t^2}=\frac{s^2}{4t^2}\\ \\ r=0.25s^2/t^2 \; \; (or) \; \; \frac{1}{4} \cdot \frac{s^2}{t^2}$

Solution for 42:

If $t$ doubled and $s$ stays constant, $r$ is multiplied by 1/4 or 0.25
