Find area of the triangle 15ft 10ft 10ft

Answers

Answer 1
Answer:

Answer:

75

Step-by-step explanation:

i'm going to assume that the base is 10, the formula for a triangle is base x height divided by 1/2 (or 2)

15height x 10base = 150 now divided by 2, 150/2 = 75

How do you factor, 45c + 10d?

Answers

We can't factor out a c or d, since we don't know c in terms of d, or vise versa.  We thus can only factor out an integer.  We see that both numbers are divisible by 5, so we factor out a 5, for a result of 5(9c+2d).  9 and 2 do not have any common factors other than 1, so we have factored fully.  Thus, the answer is 5(9c+2d).

Payments of $27.50 are made monthly for a period of 36 months, and the amount financed is $835. What is the APR using the formula above?

Answers

The monthly payment for loans with no fees is expressed by a formula. The monthly payment equation is expressed as:

P = (P° x r x (1+r)^N) / ((1+r)^N -1)

where P is the monthly payment, P° is the loan amount, r is the APR, N is the number of monthly payments

We substitute the values and manipulate where one side contains the unknown term r.

27.50/835 = ( r x (1+r)^36) / ((1+r)^36 -1)

Using some functions in the calculator we obtain,

r = 9.51 x 10^-3

Thus, the problem above has an APR of 0.95% monthly.

Answer:

12

Step-by-step explanation:

y = payments per year = 12

c = total interest paid = (36 * 27.50) - 835

m = amount financed = 835

n = total number of payments = 36

It is just a matter of finding the definitions and implementing them.

I get 12.0281484 for the exact result.

so 12 would most likely be the best answer for this.

A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 15 feet more than the length of the shortest side. Find the dimensions if the perimeter is 143 feet.

Answers

Answer:

To find the dimensions of the flower bed, we can set up an equation based on the given information. Let’s assume the length of the shortest side is x. According to the problem, one side is twice the length of the shortest side, which means it is 2x, and the third side is 15 feet more than the length of the shortest side, which means it is x + 151.

The perimeter of a triangle is the sum of all its sides. In this case, we have:

x + 2x + (x + 15) = 143.

Simplifying the equation, we get:

4x + 15 = 143.

Subtracting 15 from both sides of the equation, we have:

4x = 128.

Dividing both sides of the equation by 4, we find:

x = 32.

Now that we know the value of x, we can find the lengths of all three sides:

Shortest side: x = 32 feet.

Side twice the length of the shortest side: 2x = 64 feet.

Third side: x + 15 = 47 feet.

Therefore, the dimensions of the flower bed are approximately 32 feet, 64 feet, and 47 feet.

Trigonometric functions, fields of mathematics related to specific trigonometric functions, and their computational applications. There are six trigonometric functions commonly used in trigonometric functions. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), second (sec), and cosecant (CSC).

A function of arc or angle (sine, cosine, tangent, cotangent, second, cotangent, etc.) is most easily expressed by the ratio of the pair of sides of a right triangle.

A catapult launches a boulder with an upward velocity of 112 ft/s. The height of the Boulder, h, in feet after t seconds is given by te function h=-16t^2+112t+30. How long does it take the Boulder to reach its maximum height? What is the Boulder's maximum height ? Round to the nearest hundredth , if necessary . Please , help . I am really stuck here

Answers

Answer:

 Boulder's maximum height is 226 ft.

 It take 3.5 seconds the Boulder to reach its maximum height.

Step-by-step explanation:

Given :  

A catapult launches a boulder with an upward velocity of 112 ft/s.  

The height of the Boulder, h, in feet  

After t seconds is given by the function :


h = -16t^(2) +112t+30     --(a)

A quadratic function can be graphed using a table of values. The graph creates a parabola.


If the coefficient of the squared term is positive then the parabola opens up and The vertex of this parabola is known as the minimum point.


If the coefficient of the squared term is negative then the parabola opens down and The vertex of this parabola is known as the maximum point.


Now we will use vertex formula to calculate t

When f(x)= ax^(2) +bx+c

then vertex will be

x=(-b)/(2a)

Now consider the given function:

h = -16t^(2) +112t+30


where a = -16

b=112

so using vertex formula :

t=(-112)/(2*(-16))

t=3.5

Thus,  it take 3.5 seconds the Boulder to reach its maximum height.

Now to calculate the Boulder's maximum height . Put value of t = 3.5 in given function (a)

h = -16(3.5)^(2) +112(3.5)+30  

h = -196 +392+30  

h = 226  

Thus,  Boulder's maximum height is 226 ft.
Well we first need to do the math problem 

-b/2a = -112/2(16) = 3.5 s t= 3.5s h = -16t^2 + 112t + 30 h = -16(3.5)^2 +122(3.5) +30 h = 226

adjust the windows to y=300

3.5 s; 226 ft
