Answer:

c)11√2

Step-by-step explanation:

Given that two of the angles are equal ,each measuring 45 degrees then two legs will be equal as well each measuring 11 units. We have a right angled triangle with two sides given and we are required to determine the hypotenuse. We use Pythagoras theorem;

hypotenuse^2 = 11^2 + 11^2

hypotenuse ^2 = 242

hypotenuse = \sqrt{242}

hypotenuse = 11\sqrt{2}

The points (1, 3) and (−3, 7) lie on a line. where does the line cross the x-axis?
Anastasy [175]
First, we find the equation of the line...

(1,3),(-3,7)
slope = (7 - 3) / (-3 - 1) = 4/-4 = -1

y = mx + b
slope(m) = -1
use either of ur points.... (1,3)...x = 1 and y = 3
now sub into the formula and find b, the y int
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
so the equation for this line is : y = -1x + 4 which is usually written as :
 y = -x + 4

Now...to find where the line crosses the x axis (or the x intercept)...we sub in 0 for y and solve for x

y = -x + 4
0 = -x + 4
x = 4... so ur x intercept (where the line crosses the x axis) is : (4,0)

I have a math problem that is stumping me and other people. Do you always multiple before dividing or do you work left to right?
swat32
It is customary to work left to right, however that is not a rule.  In order of operations, the actual rule is that multiplication/division occurs after parentheses, exponents, and before addition/subtraction...

PEMDAS  order of operations

Parentheses, exponents, mutiplication/division, addition/subtraction.

Indicate a general rule for the nth term of this sequence. -6b, -3b, 0b, 3b, 6b. . .
SOVA2 [1]

The general rule for the nth term of the sequence is a(n)=-6b+(n-1)(3b)

Explanation:

The sequence is -6b, -3b, 0b, 3b, 6b, .....

To find the nth term of the sequence, we need to find the common difference and the first term of the sequence.

First term of the sequence = -6b

Common difference = -3b-(-6b)=-3b+6b=3b

Using this the nth term of the sequence can be determined.

Since, this is an arithmetic sequence, the general form of AP is given by the formula,

a(n)=a+(n-1)d

where a denotes the first term of the sequence and d denotes the common difference. Thus, a=-6b and d=3b

Substituting the values in the general formula, we get,

a(n)=-6b+(n-1)(3b)

Thus, the general rule for the nth term of the sequence is a(n)=-6b+(n-1)(3b)
