Answer:

The height of the ramp is 1.39 m.

Step-by-step explanation:

We have,

A wheelchair ramp is 8.0 m long

The angle of inclination is 10°

It is required to find the rise of  the ramp.

Here, hypotenuse is 8 m and angle of inclination is 10°.

Using trigonometry to find it.

\sin\theta=\dfrac{x}{8}

x is rise of the ramp

x=\sin(8)\times 10\\\\x=1.39\ m

So, the height of the ramp is 1.39 m.

The initial and terminal points of a vector are given. Write the vector as a linear combination of the standard unit vectors i a
gtnhenbr [62]
U=16i-4j

Explanation

any vector in the plane can be writen as a linear combination of the 2 standar unit vectors

\begin{gathered} i=\langle1,0\rangle\text{   j=}\langle0,1\rangle \\ as\text{ follows} \\ V=\langle a,b\rangle=a\langle1,0\rangle+b\langle0,1\rangle=ai+bj \end{gathered}

hence

Step 1

component form

\begin{gathered} U=\text{ terminal point -initial point} \\ U=(9-(-7),(-3-1)=\langle16,-4\rangle \end{gathered}

now, as a linear combination

U=16i-4j

Why people hate math? And what describes people how they like math
Dmitrij [34]

What do you think of when you think of maths? If you're like most people, it's probably something like: numbers, equations, boredom, anxiety and pain.

Then there are the weird ones, like me, who call themselves mathematicians. When we think of maths, we think of shapes, colours, patterns, creativity, freedom, insight and the feeling of making deep connections.

Why is there such a huge gap between how mathematicians and the general population see and experience maths?

The myth of the maths gift

So many people give up on engaging with maths from a young age, deciding, "I am just not a maths person, I'm not good at maths."

There is a deeply entrenched view in our society that ability to learn and master mathematical understanding comes from an inborn gift rather than from hard work and perseverance.

When we hold this view from a young age, the maths classroom becomes a place where we are constantly being judged not good enough, a place of repeated failure and shame.

And with each failed test, with each time we're put on the spot to answer a question we're not prepared for, we think, "See, I'm really not a maths person. Get me out of here, I don't belong."

Then grows maths anxiety.

The work of academics like Carol Dweck and Jo Boaler of Stanford University suggests that the strongest predictor of achievement in maths is mindset—specifically, whether you believe you can grow your maths ability or whether it is fixed.

Come again? You're saying I just have to believe I'm good at maths and then I can be?

Not quite.
