Given the lengths of the sides, state if the triangle is acute, obtuse, or right. 24, 37, and 40 This is a(n) blank triangle.
Karo-lina-s [1.5K]

Answer:

This is an acute triangle

Step-by-step explanation:

Pythagoras theorem is used to determine if a triangle is right, acute or obtuse

If the sum of squares of two shorter lengths is greater than the square of third side then the triangle is an acute triangle.

If the sum of squares of two shorter lengths is less than the square of third side then the triangle is an obtuse triangle.

If the sum of squares of two shorter lengths is equal the square of third side then the triangle is a right triangle.

so,

(40)^2 = (37)^2 + (24)^2\\1600 = 1369+576\\1600

As 1600<1945, the given triangle is an acute triangle ..

The total number of fungal spores can be found using an infinite geometric series where a1 = 8 and the common ratio is 4. Find t
Dmitry [639]
The formula for infinite geometric series is equal to a1 / (1-r) where in this problem a1 is equal to 8 and r is equal to 4. In this case, r is not equal to less than 1. This means the sum should be infinity and cannot be determined definitely.

Rationalize the denominator of the given expression
Grace [21]

You multiply top and bottom of the fraction by the conjugate of 5 - √2  which is 5 + √2.   This produces a rational denominator:-

=    √7 ( 5 + √2)  /   (5 - √2)(5 + √2)

=  √7 ( 5 + √2) /   (25 -2)

=   (√7 ( 5 + √2)) / 23    answer

How many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22
Step2247 [10]

Answer:

x = 4, y = -3

Step-by-step explanation:

{2x - y = 11

{x + 3y = -5

You can use the substitution method by solving for x in the second equation:

x + 3y = -5

Subtract 3y from both sides:

x = -3y - 5

Now, substitute this value for x into the first equation:

2x - y = 11

2(-3y - 5) - y = 11

Distribute:

-6y - 10 - y = 11

Add 10 to both sides:

-6y - y = 21

Combine like terms:

-7y = 21

Divide both sides by -7:

y = -3

Next, substitute this value for x into the second equation:

x + 3y = -5

x + 3(-3) = -5

Multiply:

x - 9 = -5

Add 9 to both sides:

x = 4
