Answer:

97 points

Step-by-step explanation:

Given,

His scores, in first test = 90 points,

In second test = 82 points,

In third test = 95 points,

In fourth test = 86 points,

Let he scores x points on the fifth test,

Thus, the total sum of the scores in five tests = 90 + 82 + 95 + 86 + x

= 353 + x

Also, The Average scores in these five test = 90

We know that,

\text{Average score}=\frac{\text{Total sum of the scores}}{\text{Total number of tests}}

Here, total number of tests = 5,

90=\frac{353+x}{5}

450=353+x\implies x = 450-353=97

Hence, the lowest score he can get on the fifth test and still finish with an average score of 90 points is 97 points.

Answer:

2.

a)1

b)1

c)1

Step-by-step explanation:

There's some identity trigonometric equation, which are valid for all angles,and they doesn't depends on the measure of angle!

some of em are follows:. (x is the given angle)

  • sin(x)^2+cos(x)^2=1
  • cosec(x)^2=1+cot(x)^2
  • sec(x)^2=1+tan(x)^2

You can remember these identity, its gonna help alot.

now back to question,. {x is representing angles)

for (a) sin(x)^2+cos(x)^2=1, this is true for all x, dat means that for all the angle given in question(for ,15°,30°,45°,60° and 120°),we will get 1

for(b) ,

cosec(x)^2=1+cot(x)^2

i.e, cosec(x)^2-cot(x)^2=1, again this is true for all x dat means that for all the angle given in question ,we will get 1

for (c),

sec(x)^2=1+tan(x)^2

i.e,sec(x)^2-tan(x)^2=1,again this is true for all x, dat means that for all the angle given in question ,we will get 1

Which of the following is equal to the rational expression when x -2 or -6?
kykrilka [37]

The given expression is

f(x) = \frac{3(x+2}{(x+2)(x+6)}

And since we have x+2 common in numerator and denominator, there is a hole at x+2=0, that is at x=-2

And a function is undefined when denominator is zero. And at x=-6, denominator become zero.

So, at x=-6, the function is undefined, or there is a vertical asymptote at x=-6 and hole at x=-2 .

Please help easy stuff.......
nataly862011 [7]

To evaluate a function at a given input, you have to substitute every occurrence of the variable with that particular value.

So, for the first function, you have

T(x) = -x-2 \implies T(-4) = -(-4)-2 = 4-2 = 2

The name of the variable is obviously irrelelvant, so the same goes for the second function:

w(x) = 14-6x \implies w(-3) = 14-6\cdot(-3) = 14 + 18 = 32
