Answer:
1+2x=13
Step-by-step explanation:
the sum of= +
one=1
products of a number and 2= 2x
equals= =
thriteen=13
Put them all together:
1+2x=13
{4x - 5y = 17
{x - 5y = 8
{x = 5y + 8
{4(5y + 8) - 5y = 17
{x = 5y + 8
{20y + 32 - 5y = 17 | - 32
{x = 5y + 8
{15y = -15 | : 15
{y = -1
{x = 5 * (-1) + 8
{x = 3
{y = -1
Step-by-step explanation:
Pythagoras (for right-angled triangles) :
c² = a² + b²
c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.
c = diagonal = 10 ft
therefore, the width of the rectangle is 10/2 = 5 ft
10² = 5² + b²
100 = 25 + b²
b² = 75
b = length = sqrt(75) = 8.660254038... ft
The answer is $19,360 because we multiply the annual interest rate of 6% or .06 by 3.5 years and we get a total interest of .21. The answer is found by performing $16,000 times 1.21 and we get $19,360.
Answer:
It is given that : 
As we have to find the Domain of 
.
-1 ≤ sin x ≤1
So it is defined for x lying between 
.
As meaning of Domain is those values of x for which any function f(x) is defined.
