Answer:
[tex]103.78\:\mathrm{ft}[/tex]
Step-by-step explanation:
We can form a right triangle where the distance between the ranger's current position and fire is the hypotenuse of the triangle. In a right triangle, the tangent of an angle is equal to its opposite side divided by the hypotenuse.
Therefore, we have:
[tex]\tan 34^{\circ}=\frac{70}{x}[/tex], where [tex]x[/tex] is the distance between the base of the tower and the fire.
Solving, we get:
[tex]x=\frac{70}{\tan 34^{\circ}}=103.779267796\approx \boxed{103.78\:\mathrm{ft}}[/tex]

SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. 1) Write the equation of the line x 3y
Answer:
[tex]y = -3x + 14[/tex]
Step-by-step explanation:
Required
The equation of line
perpendicular to : [tex]x -3y =9[/tex]
Passes through [tex](3,5)[/tex]
We have:
[tex]x -3y =9[/tex]
Make y the subject
[tex]3y =x - 9[/tex]
Solve for y
[tex]y = \frac{x}{3} - 3[/tex]
Compare the above equation to [tex]y = mx + c[/tex]
[tex]m =\frac{1}{3}[/tex] ---- This represents the slope
Since the line is perpendicular to [tex]x -3y =9[/tex], then its slope is:
[tex]m_2 = -\frac{1}{m}[/tex]
[tex]m_2 = -\frac{1}{1/3}[/tex]
[tex]m_2 =-3[/tex]
The equation of the perpendicular line is:
[tex]y =m_2(x - x_1) + y_1[/tex]
Where:
[tex]m_2 =-3[/tex]
[tex](x_1,y_1) =[/tex] [tex](3,5)[/tex]
So:
[tex]y = -3(x - 3) + 5[/tex]
[tex]y = -3x + 9 + 5[/tex]
[tex]y = -3x + 14[/tex]

A cylinder has a volume of 187 cubic inches. If the radius is 3 inches, what is the height of the cylinder in inches?
Someone please help
Answer:
Step-by-step explanation:
V = pi r^2 h
V = 187
pi = 3.14
r = 3
h = ?
187 = 3.14 * 3^2 * h
187 = 3.14 * 9 * h
187 = 28.26 * h
187 / 28.26 = h
h = 6.62
Answer:
The height of cylinder is 6.61 inches.
Step-by-step explanation:
Given that :- Volume of cylinder = 187 inches ³.Radius of cylinder, r = 3 inchesWe need to Find :-Height of cylinder , h Formula Used :-Volume of cylinder = π × r ² × h
Where,
r is the radius of cylinder. h is the height of cylinder.Solution :-Using Formula
Volume of cylinder = π × r ² × h
Substitute the values
187 inches ³ = π × ( 3 inches ) ² × h
Using π = 3.14
187 inches ³ = 3.14 × 9 inches ² × h
multiply
187 inches ³ = 28.26 inches ² × h
Divide , we get
187 inches ³ / 28.26 = h
6.61 inches = h
Therefore, The height of cylinder is 6.61 inches.

I need help with this simple Geometry Question
Answer: 132º
Step-by-step explanation:
Since <QSR is an inscribed angle, that means that the intercepted arc, which is arc QR, is twice the measure of that angle, which is 132º. Since <QPR is a center angle, it is equal to its center arc. So, <QPR is 132º.
If a seed is planted, it has a 90% chance of growing into a healthy plant. If 10 seeds are planted, what is the probability that exactly 2 don't grow
The probability that exactly 2 seeds will don't grow will be equal to 0.193.
What is Probability?Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.
As per the given information in the question,
P(2 don't grow) = P(8 will grow)
Use the formula given below,
P(X = r) = [tex]^nC_r\ p^r(1-p)^{n - r}\\[/tex]
P(X = 8) = ¹⁰C₂ (0.9)⁸(0.1)²
= 45 × 0.43 × 0.01

The position of an atom moving inside a cathode ray tube is given by the function f(t) = t^3− 4t^2 + 3t where t is in seconds and f(t) is in meters. Find the instantaneous velocity of the atom at t = 2.5 seconds. A. 1.75 m/sec. B. 2.48 m/sec. C. 3.27 m/sec. D. 4.12 m/sec.
Answer:
A
Step-by-step explanation:
The position of an atom moving inside a cathode ray tube is given by the function:
[tex]f(t)=t^3-4t^2+3t[/tex]
Where f(t) is in meters and t is in seconds.
And we want to determine its instantaneous velocity at t = 2.5 seconds.
The velocity function is the derivative of the position function. Thus, find the derivative of the function:
[tex]f'(t)=3t^2-8t+3[/tex]
Then the instantaneous velocity at t = 2.5 will be:
[tex]f'(2.5)=3(2.5)^2-8(2.5)+3=1.75\text{ m/sec}[/tex]
Our answer is A.
Answer:
Instantaneous Velocity:
[tex]\longrightarrow\:\rm v = \dfrac{dt}{dy}[/tex]
[tex]\longrightarrow\:\rm v = \dfrac{d}{dy}( {t}^{3} - 4 {t}^{2} + 3t) \\ [/tex]
[tex]\longrightarrow\:\rm v = 3 {t}^{3 - 1} - 2.4 {t}^{2 - 1} + 3[/tex]
[tex]\longrightarrow\:\rm v = 3 {t}^{2} - 8 t + 3[/tex]
[tex]\longrightarrow\:\rm v = 3 {(2.5)}^{2} - 8 (2.5)+ 3[/tex]
[tex]\longrightarrow\:\rm v = 3 \times 6.25 - 20+ 3[/tex]
[tex]\longrightarrow\:\rm v = 18.75 - 20+ 3[/tex]
[tex]\longrightarrow\:\rm v = 18.75 - 20+ 3[/tex]
