Write cos 23 degrees in terms of sine

Answers

Answer 1

Answer:

Answer:

0.3907.

Step-by-step explanation:

Using trigonometric identities, we can write cos 23° in terms of sin 23° as, cos(23°) = √(1 - sin²(23°)). Here, the value of sin 23° is equal to 0.3907.

Answers

Answer:

A and D

Step-by-step explanation:

In this question, we are asked to select the expressions that represent the number of vacation days per x days worked.

Now, to do this, what we simply first do is to get the number of days to takes to get one paid vacation. In the question , we are made to know that he gets 3 days paid vacation for 60 days of work. The number of days to get a single paid vacation would thus be 60/3 = 20 days. This means she gets one paid vacation in 20 days.

Now, we are told after working for x days, how many paid days vacation does she get. To know this, what we do is to first know the number of 20 days in x days. That would simply be x/20. This is the number of vacation days she gets in x days.

now, we check if there are similar options to this.

D is also correct. This is because x/20 is same as 0.005x

X = ?

17 - x = 13

Solve for x.

Thanks in advance.

Answers

To solve for x we will do the following steps. Then we will check our work. Lets do it:-

17 - x = 13
17 - 13 = x
17 - 13 = 4
x = 4

CHECK OUR WORK:-

17 - 4 = 13
We were RIGHT!!!

So, x = 4.

Hope I helped ya!!

17 - 4 = 13.

The height (in feet) of punted football is a function of the time the ball is in the air. The function is defined by h(t) = - 7t ^ 2 + 48t . What is the height of the football after 4 seconds?

Answers

The height of the football after 4 seconds is 80 feet

The height in feet of the punted football is a function of time the ball is in the air.

The function is represented as follows:

h(t) = -7t² + 48t

The height of the football after 4 seconds can be calculated as follows:

h(t) = -7t² + 48t

where

t = 4 seconds

Therefore,

h(4) = 7(4)² + 48(4)

h(4) = -7(16) + 192

h(4) = -112 + 192

h(4) = 80 feet

Answer:

The height of the football after 4 seconds is 80 feet.

Step-by-step explanation:

You know that the height (in feet) of punted football is a function of the time the ball is in the air and it is defined by:

h(t) = -7*t²+48*t

To calculate the height of the ball after 4 seconds, you must replace the time t by the time of 4 seconds:

h(4) = -7*4²+48*4

Solving, you get:

h(4) = -7*16+48*4

h(4) = -112+192

h(4)= 80

The height of the football after 4 seconds is 80 feet.

1. (-1,4)(1,4)(-2,4)(2,4) is a function because it has no repeating x values.

2. A is a subset of B because everything in A is in B ?? not sure exactly what u r looking for

3. a(b*c) = (a*b)c.....associative property

4. the intersection of A and C is { empty set } because they have no letters in common

5. range is all ur y values....so the range of G is { 0,2,6,7 }
