neonofarm [45]

Answer: See step by step. Replace the x with theta

Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.

We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.

We can find tangent by using the identity

$tan^{2} (x)+ 1=sec^{2} (x)$ where x is theta.

$tan^{2} (x)+1=\frac{289}{225}$

$tan^{2} (x)+\frac{225}{225} =\frac{289}{225}$

$tan^{2}(x)=\frac{64}{225}$

tan x= $\frac{8}{15}$ , Tangent in the fourth quadrant is negative so the answer is instead

$tan x= -\frac{8}{15}$

We can find cotangent by taking the recipocial of tan so

$cot=-\frac{15}{8}$

We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is

$cos =\frac{15}{17}$

We can find sin by doing quoteint identies.

$\frac{sin x}{cos x} =tan x$

$\frac{ sin x}{15/17} =-\frac{8}{15}$

$sin x= -\frac{8}{17}$

To find csc, take reciprocal of sine.

$csc=\frac{-17}{8}$

Find the real zeros 4x²-16x + 2.5x

Lapatulllka [165]

I am going to assume 2.5x is really 25x (typo).

First formulate the equality

$4x^2-16x+25x=0 \\4x^2+9x=0 \\x(4x+9)=0 \\$

Now two results emerge.

$x_1=0, x_2=-\dfrac{9}{4}$ .

Hope this helps.

Find the volume of the solid. When appropriate, use π=3.14 and round your answer to the nearest hundredth.

Elenna [48]

Answer:

3179.25

Step-by-step explanation:

Hello!

To find the volume of a cylinder we use the equation

$V = \pi r^{2} h$

V is volume

r is radius

h is height

Put in what we know. It is says to use pi as 3.14

$V = 3.14 * 7.5^{2} *18$

Solve

V = 3.14 * 56.25 * 18

V = 3179.25

Hope this Helps!
