Answer:

h[g{f(x)}] = -(8x² + 40x + 50) is the answer.

Step-by-step explanation:

The given functions are f(x) = 2x + 5 , g(x) = x² and h(x) = -2x.

We have to find the value of h[g{f(x)}]

To get the value we will find the value of g{f(x)} first.

g{f(x)} = (2x + 5)²= 4x²+ 25 + 20x

Then we will find the value of h[g{f(x)}]

h[g{f(x)}] = -2(4x²+ 20x + 25) = (-8x² - 40x -50)

So the answer is h[g{f(x)}] = -(8x² + 40x + 50)

Answer:

h(g(f(x)))= -8x²-40x-50

Step-by-step explanation:

We have given three function.

f(x) = 2x + 5 and g(x) = x² and h(x) = -2x

we have to find h(g(f(x))).

h(g(f(x))) = ?

Putting value , we have

h(g(f(x))) = h(g(2x+5)

h(g(f(x))) = h((2x+5)²)

h(g(f(x))) = h(4x²+20x+25)

h(g(f(x))) = -2(4x²+20x+25)

h(g(f(x))) = -8x²-40x-50 which is the answer.

Can someone PLEASE help me with Trigonometry???

Svetach [21]

$\bf sin^2(2\theta)-7sin(2\theta)-1=0\\\\
-------------------------------\\\\
sin(2\theta)=\cfrac{7\pm\sqrt{49-4(1)(-1)}}{2(1)}\implies sin(2\theta)=\cfrac{7\pm\sqrt{49+4}}{2}
\\\\\\
sin(2\theta)=\cfrac{7\pm\sqrt{53}}{2}\implies 2\theta=sin^{-1}\left( \frac{7\pm\sqrt{53}}{2} \right)
\\\\\\
\theta=\cfrac{sin^{-1}\left( \frac{7\pm\sqrt{53}}{2} \right)}{2}$

but anyway, the numerator will give the angles, and θ is just half of each

$\bf \theta=\cfrac{sin^{-1}\left( \frac{7\pm\sqrt{53}}{2} \right)}{2}\\\\
-------------------------------\\\\
sin^{-1}\left( \frac{7+\sqrt{53}}{2} \right)\implies sin^{-1}(7.14)\impliedby \textit{greater than 1, no good}
\\\\\\
sin^{-1}\left( \frac{7-\sqrt{53}}{2} \right)\implies sin^{-1}(-0.14) \approx -8.05^o
\\\\\\
\theta=\cfrac{-8.05}{2}\implies \theta=-4.025$

ok... that's a negative tiny angle, is in the 4th quadrant, if we stick to the range given, from 0 to 360, so we have to use the positive version of it, 360-4.025

so the angle is 355.975°

now, the 3rd quadrant has another angle whose sine is negative, so... if we move from the 180° line down by 4.025, we end up at 184.025°

and those are the only two angles, because, on the 2nd and 1st quadrants, the sine is positive, so it wouldn't have an angle there

Solve the following pair of simultaneous equation using elimination method.

sp2606 [1]

Answer:

x = 1 and y = −2

Step-by-step explanation:

Rewrite equations:

x + 2y = −3

3x − 2y = 7

Step 1: Solve x+2y=−3 for x:

x + 2y = −3

x + 2y + −2y = −3 + −2y (Add -2y to both sides)

x = −2y − 3

Step 2: Substitute −2y − 3 for x in 3x − 2y = 7:

3x − 2y = 7

3(−2y − 3) − 2y = 7

−8y − 9 = 7 (Simplify both sides of the equation)

−8y − 9 + 9 = 7 + 9 (Add 9 to both sides)

−8y = 16

−8y/−8 = 16/−8 (Divide both sides by -8)

y = −2

Step 3: Substitute −2 for y in x = −2y − 3:

x = −2y − 3

x = (−2)(−2) − 3

x = 1 (Simplify both sides of the equation)

Henry’s disability insurance pays 70% of his salary for up to 26 weeks if his salary is $450 and he is disabled for 20 weeks how

ankoles [38]

Answer:

$1575

Step-by-step explanation:

70 % of his salary is 0.7 X 450 = 315

He gets it for 20 weeks

presuming the salary is monthly.

You do 315 X 5 = 1575 20 /4 = 5 months
