sin90°/47 = sin17°/x

xsin90° = 47sin17°

x = 47sin17°/sin90°

x = 13.741470121969

x ≈ 13.74

Hope this helps! ;)

Answer: 13.7

Step-by-step explanation:

Since it is a right angled triangle , we will apply SOHCAHTO, that is

sine = opposite/hypotenuse

cosine = adjacent / hypotenuse

Tangent = opposite / adjacent

From the diagram

opposite = x

hypotenuse = 47

This means that we are using sine , that is

sine 17 = x/ 47

x = 47sin 17

x = 47 x0.29233717047

x = 13. 74147012

to the nearest tenth

x = 13.7

Find the value of root 121 + 3 over root 125

NemiM [27]

Answer:

$\mathrm{Decimal:\quad }\:1.25219\\\frac{14\sqrt{5}}{25}$

Step-by-step explanation:

$\frac{\sqrt{121}+3}{\sqrt{125}}\\\sqrt{125}=5\sqrt{5}\\=\frac{\sqrt{121}+3}{5\sqrt{5}}\\\sqrt{121}=11\\=\frac{11+3}{5\sqrt{5}}\\\mathrm{Add\:the\:numbers:}\:11+3=14\\=\frac{14}{5\sqrt{5}}\\\mathrm{Rationalize\:}\frac{14}{5\sqrt{5}}:\quad \frac{14\sqrt{5}}{25}\\=\frac{14\sqrt{5}}{25}$

In the equation f(x)= 5(x+3)^2-10 what effect does the 5 do when compared to the parent function?

Lostsunrise [7]

Answer:

The correct answer is A. Vertical compress by a factor of 5

Step-by-step explanation:

When graphed without the 5, the curve is very wide, but when the 5 is added, the curve compresses and narrows itself, therefore a vertical compress occurs by the factor of 5.
