Which of the following transformations is an example of a non-rigid transformation?

Answers

Answer:

R to S

Step-by-step explanation:

Here, we want to get the transformation that is non-rigid

Looking at the plot, only R is facing an entirely different direction

What this mean is that by moving others across the x and y axes, we can get the transformation between them

But in the case involving R such as the transformation between R and S; merely translation is not enough

There has to be rotation and thus, in that case, it is a non-rigid transformation

The length of a rectangle is 4 yd more than twice the width x. The area is 390
yd. Find the dimensions of the given shape.

Answers

Step-by-step explanation:

step 1. let l be the length of the rectangle

step 2. l = 2x + 4

step 3. lx = 390 yd^2

step 4. (2x + 4)x = 390

step 5. 2x^2 +4x = 390

step 6. 2x^2 + 4x - 390 = 0

step 7. -4 +- sqr(4^2 -4(2)(-390))/2(2) quadratic formula

step 8. (-4 +- sqr(3136))/4

step 9. (-4 +- 56)/4

step 10. x = 13yd, l = 2x + 4 = 2(13) + 4 = 30yd.

Please help me on math and explain how to get the answer.

Answers

Answer:

x = 128

Step-by-step explanation:

ill name the empty angle y for clarification

y + 38 + 90 = 180

y + 128 = 180

y = 52

180 - y = x

180 - 52 = x

x = 128

so here’s what i am thinking, so the right angle itself is 90°, and the top is 38°. a triangle adds up to 180° so add the 90 and 38 and then subtract it from 180. That itself gives 52°. the straight line is 180°, so you’d subtract 52° from 180° to get the outer angle, so the answer should be 128°.

there are 10 ipil-ipil seedling to 3 narra seedling. there are 12 narra seedlings for_____ipil-ipil seedlings.

Answers

Answer:

40

Step-by-step explanation:

Given :

10 ipil-ipil seedling to 3 Narra seedling

x ipil-ipil seedling for 12 Narra seedling

Using cross multiplication :

10 = 3

x = 12

Cross multiply

3 * x = 10 * 12

3x = 120

Divide both sides by 3

3x / 3 = 120 / 3

x = 40

Hence we have

40 ipil-ipil seedling to 12 Marra seedling

A flagpole is 12 feet tall. If the flagpole casts a 50-foot shadow, then what is the angle of elevation to the sun?
А
76.5
B
51.4
4.2
D
13.5

Answers

Answer:

[tex]\theta=13.5^{\circ}[/tex]

Step-by-step explanation:

Given that,

The height of a flagpole, h = 12 feet

the height of the shadow, b = 50 feet

We need to find the angle of elevation of the sun. Let it is be θ. Using trigonometry to find it.

[tex]\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{12}{50}\\\\\theta=13.49^{\circ}\\\\or\\\theta=13.5^{\circ}[/tex]

So, the angle of elevation to the sun is equal to [tex]13.5^{\circ}[/tex].
