What angle is an x–intercept for the function y= cos(.5x)

Mathematics

Ksenya-84 [330]3 years ago
5 0
X-intercept appears at when y = 0

So when cos(0.5x) = 0 -> 0.5x = pi/2 + n*pi, where n is any random integers

So x = pi + 2npi, so the angle can be pi, 3pi, 5pi, so on

1. - 2(x + 11) = -18
77julia77 [94]

Answer:

x = - 2

Step-by-step explanation:

Step 1:

-2 ( x + 11 ) = - 18         Equation

Step 2:

- 2x - 22 = - 18       Multiply

Step 3:

- 2x = 4       Add 22 on both sides

Step 4:

x = 4 ÷ - 2

Answer:

x = - 2

How do you solve this? A and B
svp [43]
An adult polar bear is 8 times longer than a newborn.
Newborn= 12 1/2 ft
Multiply this by 8.
But first you have to turn the fraction
12 1/2 into an improper fraction. To do this you have to multiply the denominator, 2, by the whole number, 12, and add the numerator to the product, which totals to 25. The fraction is 25/2. (25/2 * 8/1)= 100 in simplified. 100 inches= 8 1/3 ft long
A= 8 1/3 ft long.
For B, you are dividing since you are trying to figure out the length of a newborn, not an adult polar bear. 9/8 turned into a mixed fraction is
1 1/8 ft. But, it asks in inches. 
B= 13 1/2 inches
I know this answer is very long but I hope it helps you understand better!

A washer and dryer cost 1003 combined the washer cost 53 more than dryer what’s the cost of dryer
NeX [460]

Answer:

475

Step-by-step explanation:

Let's call the dryer price is x

Then, the price for the washer is 53 more than the dryer, it would be: x+53

Total price of washer and dryer = 1003

We get the equation:

x+(x+53) = 1003

2x + 53 = 1003

2x + 53 - 53 = 1003 - 53

2x = 950

x = 475

The dryer price is 475

Extra: you can find the cost of the washer by using x+53 = 475+53 = 528

The perimeter of a square is 44 centimeters. what is its area?
aalyn [17]

Answer:

Perimeter = 44cm

we know that square has 4 sides which are same

so perimeter means sum of all 4 sides

4 × s = 44cm

s = 11cm

Each side will be of 11cm.

Now area of square is Square of its side length.

so area = 11 × 11 = 121 cm^2

What is the equation, in slope-intercept form, of the line that is perpendicular to the line
Len [333]

Answer:

y = x - 1 (third answer choice)

Step-by-step explanation:

From the given we see immediately that the slope of this line is -1.  The slope of a line perpendicular to this one is +1, which is the negative reciprocal of -1.  The slope-intercept form is y = mx + b.  To find b, the y-intercept, we make the following substitutions:  m = -1, y = -2, x = -2:

-2 = +1(-2) + b, or +1 = 2 + b, or b = -1

and so the desired equation is y = x - 1 (third answer choice)
