Find the value of x. Round to the nearest tenth.

Mathematics
1 answer:
dusya [7]3 years ago
5 0

Answer:

x = 10.2

Step-by-step explanation:

Here we have a right triangle with hypotenuse 11, angle 22° and adjacent side x.  Our task is to find x to the nearest tenth.

The cosine function nicely connects the hypotenuse and the adjacent side:

                 adjacent side

cos 22° = ------------------------

                     hypotenuse

We solve for the adjacent side (x) by multiplying both sides of this equation by "hypotenuse:"

x = adjacent side = 11*cos 22 = 11(0.9272 radian).

Performing the indicated multiplication, we arrive at:

x = 10.1990, or, rounded to the nearest tenth, x = 10.2.

Answer:

<h2>Q4. (-7)</h2><h2>Q5. (-8)</h2>

Step-by-step explanation:

The perfect square:

(a+b)^2=a^2+2ab+b^2

Q4

We have

y^2+14y+49=0\\\\y^2+2(y)(7)+7^2=0\\\\(y+7)^2=0\iff y+7=0\qquad\text{subtract 7 from both sides}\\\\\boxed{y=-7}

Q5

We have

y^2+16y+64=0\\\\y^2+2(y)(8)+8^2=0\\\\(y+8)^2=0\iff y+8=0\qquad\text{subtract 8 from both sides}\\\\\boxed{y=-8}

Rashaj has $37.25 in his wallet. He would
Butoxors [25]

I agree. From the calculation, the total <em>amount spent </em><em>is </em><em>less than</em><em> (<)the amount in his pocket</em>, this means that <em>Rashaj can buy 5 boxes of candy. </em>

Inequalities are expressions that are not always equal to each other. The inequality signs are <, > ≤ and ≥

Given the following

Amount Rashaj has in his wallet = $37.25

Amount spent

A movie ticket = $7.25

5 boxes of candy at $3.75 per box = 5($3.75) = $18.75

Taking the sum of the total amount spent

Amount spent = $7.25 + $18.75

Amount spent = $26

Since the total <em>amount spent </em><em>is </em><em>less than</em><em> (<)the amount in his pocket</em>, this means that <em>Rashaj can buy 5 boxes of candy. </em>

Finding values or<br> k(x) = x - 2<br> h(x) = x2 +1<br> (h + k)(2) =
Serjik [45]

Answer:

<h2>(h + k)(2) = 5</h2>

Step-by-step explanation:

(h+k)(x)=h(x)+k(x)\\\\\bold{METHOD\ 1:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(k+h)(2)=h(2)+k(2)\\\\\text{Calculate}\ h(2)\ \text{and}\ k(2).\\\text{Put}\ x=2\ \text{to the equations of the functions}\\\\h(2)=2^2+1=4+1=5\\k(2)=2-2=0\\\\\text\\\\\text{Substitute:}\\\\(h+k)(2)=5+0=5

\bold{METHOD\ 2:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(h+k)(x)=h(x)+k(x)=(x^2+1)+(x-2)=x^2+x-1\\\\(h+k)(2)-\text{put}\ x=2\\\\(h+k)(2)=2^2+2-1=4+2-1=6-1=5
