Answers

Answer 1

Answer:

Step-by-step explanation:

Take angle A as reference angle

using cosec rule

cosec A=hypotenuse/opposite

cosec A=13/5

cosec A=2.6

A=cosec 22.5

A=22.5

for ratio,

cosec A=13/5

PLEASE HELP SOLVE FOR PT. A AND B

Answers

Answer:

a=1; b=14

Step-by-step explanation:

you have to form a perfect square

(a+b)²=a²+b²+2ab

If you add a one you will get a perfect square

x²+2x+1 = (x+1)²

if you added a one in one side you have to added to the other side too

(x+1)² = 13+1

(x+1)² = 14

Answer:

a = 1, b = 14

Step-by-step explanation:

To complete the square

add ( half the coefficient of the x- term)² to both sides , that is

x² + 2(1)x + 1 = 13 + 1

(x + 1)² = 14

with a = 1 and b = 14

Given you or a person holding a kite string 100 feet long write and draw what the height or altitude the kite is off the ground if the angle of elevation is 49 HELP!

Answers

Answer: [tex]75.47\ ft[/tex]

Step-by-step explanation:

Given

String of the kite is [tex]l=100\ ft[/tex]

Angle of elevation [tex]\theta=49^{\circ}[/tex]

suppose altitude of the kite is h

from the figure, we can write

[tex]\Rightarrow \sin 49^{\circ}=\dfrac{h}{100}\\\\\Rightarrow h=100\sin 49^{\circ}\\\\\Rightarrow h=75.47\ ft[/tex]

Thus, the altitude of the kite is [tex]75.47\ ft[/tex]

6. Find the sum of the geometric series.
a1=-9 a5=-729 r=-3

Answers

Answer:

Sn = -9(1-(-3)^n)/4

Step-by-step explanation:

Since r < 1, the sum of nth term of a geometric sequence is expressed as;

Sn = a(1-r^n)/1-r

a is the first term

n is the number f terms

r is the common ratio

An = -9(1-(-3)^n)/1-(-3)

Sn = -9(1-(-3)^n)/4

Hence the sum of the nth term of the series is Sn = -9(1-(-3)^n)/4

Write a quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, −17) .
f(x)=

Answers

Answer:

Step-by-step explanation:

Given,

Vertex (h, k ) = (1,0)

Now,

We know,

f(x) = a(x-h)²+k

Since, it passess through (2, −17)

Put x = 2 and y = - 17

or, -17 = a(2 - 1)² + 0

or, -17 = a

Now,

f(x) = a(x - h)² + k

= -17(x - 1)² + 0

= -17x² + 34x - 17

Answers

Answer:

[tex]p(t) = \frac{9t^{3} + 729t - 1}{e^{t}(t^{2} + 81) }[/tex]

g(t) = 0

And

The differential equation [tex]9ty + e^{t}y' = \frac{y}{t^{2} + 81 }[/tex] is linear and homogeneous

Step-by-step explanation:

Given that,

The differential equation is -

[tex]9ty + e^{t}y' = \frac{y}{t^{2} + 81 }[/tex]

[tex]e^{t}y' + (9t - \frac{1}{t^{2} + 81 } )y = 0\\e^{t}y' + (\frac{9t(t^{2} + 81 ) - 1}{t^{2} + 81 } )y = 0\\e^{t}y' + (\frac{9t^{3} + 729t - 1}{t^{2} + 81 } )y = 0\\y' + [\frac{9t^{3} + 729t - 1}{e^{t}(t^{2} + 81) } ]y = 0[/tex]

By comparing with y′+p(t)y=g(t), we get

[tex]p(t) = \frac{9t^{3} + 729t - 1}{e^{t}(t^{2} + 81) }[/tex]

g(t) = 0

And

The differential equation [tex]9ty + e^{t}y' = \frac{y}{t^{2} + 81 }[/tex] is linear and homogeneous.

Find the y-coordinate of the y-intercept of the polynomial function defined
below.
f(x) = 9x^2 – 7 – 8x

Answers

The y intercept is where the function passes through the y axis, so the “x” value needs to equal 0. We sub 0 in for “x” and solve for “y”.

f(0) = 9(0)^2 - 7 - 8(0)

f(0) = -7

Therefore the “y” coordinate would be -7

The ordered pair would be

Step-by-step explanation:

Volume = 4,410 yd
30 yd
radius =

Answers

Answer:

Radius = 11.85yd

Step-by-step explanation:

Volume of a Cone formula: V = πr²(h/3)

We know that;

V = Volume

r = radius

π = pi (this is a sign located on your calculator)

h = height

We are given that;

V = 4,410

r = unknown

h = 30

Let's substitute the values in:

=> V = πr²(h/3)

=> 4,410 = πr²(30/3)

=> 4,410 = πr²(10)

=> 4,410 / 10 = πr²

=> 441 = πr²

=> 441 / π = r²

=> 140.37 = r²

=> [tex]\sqrt{140.37}[/tex] = r

=> 11.85 = r

Therefore, the radius of the cone = 11.85yd

What is the recursive and explicit formula of the geometric sequence?
2,5, 12.5, 31.25, 78, 125, ...

Answers

Answer:

Option (2)

Step-by-step explanation:

Given geometric sequence is,

2, 5, 12.5, 31.25, 78.125......

First term = a₁ = 2

Common ratio of the sequence = r = [tex]\frac{5}{2}[/tex]

= 2.5

Recursive formula of a geometric sequence is given by,

[tex]a_n=a_{n-1}(r)[/tex]

Here, [tex]a_n=[/tex] nth term of the sequence

[tex]a_{n-1}=[/tex] (n - 1)th term

r = common ratio

Therefore, recursive formula for the given sequence will be,

[tex]a_1=2[/tex]

[tex]a_n=a_{n-1}(2.5)[/tex]

Explicit formula of a geometric sequence is given by,

[tex]a_n=a_1(r)^{n-1}[/tex]

Therefore, explicit formula of the sequence will be,

[tex]a_n=2(2.5)^{n-1}[/tex]

Option (2) will be the correct option.

Find the value of each variable in the parallelogram.

The co-secant of angle A is √85 / 6. And that angle A is in Quadrant I.

Then the value of angle A will be

csc A = √85 / 6

1 / cos A = √85 / 6

cos A = 6 / √85
