Answer:
The value of x is incorrect he should be using 28/21 instead of 21/28
Step-by-step explanation:
tan = opp/adj
tanx = 28/21
The value of x is incorrect he should be using 28/21 instead of 21/28
Answer:
A) The value of x is incorrect. He should be using 28/21 instead of 21/28.
Step-by-step explanation:
Recall that [tex]tan\theta=\frac{opposite}{adjacent}[/tex]. This means that the correct setup would be [tex]tan\theta=\frac{28}{21}[/tex] since 28 is opposite of x° and 21 is adjacent to x°. Thus, your solution would be [tex]x^{o}=tan^{-1}(\frac{28}{21})=53.13010235^o\approx53.1^o[/tex]

Answer:
24/18 OR 4/3 OR 1.3333...
Step-by-step explanation:
18y - 17 = 7
Add 17 from both sides.
18y = 24
Divide 18 from both sides to leave the y alone.

1) (-5,4), (ii)(4,-2) (iii) 7,2) (iv) (-3,-7)
Answers
Answer:
Step-by-step explanation:
(-5,4)=since x coordinate is negative and y coordinate is positive it lies on 2 nd quadrant.
(4,-2)=x coordinate is positive and y coordinate is negative so it lies on 4 th quadrant
(7,2)=both x coordinate and y coordinate are positive so they lie in 1 st quadrant.

Equation practice with angle addition
Answers
Answer:
m<BOC = 60°
Step-by-step explanation:
First, we will need to determine the value of x
m<BOC + m<AOB = m<AOC (angle addition postulate)
Substitute
9x + 42 + 7x + 30 = 104
Collect like terms
16x + 72 = 104
16x + 72 - 72 = 104 - 72
16x = 32
x = 32/16
x = 2
✔️m<BOC = 9x + 42
Plug in the value of x
m<BOC = 9(2) + 42
m<BOC = 18 + 42
= 60°

Helen rented a kayak at the lake. There is a charge of $10 as an initial fee and then $2 an hour for every hour that she uses the kayak. If the total charge is $22 , how many hours did she kayak?
Answers
Answer:
She kayaked for 6 hours.
Step-by-step explanation:
If $10 is the initial fee, subtract $22 - $10 = $12.
If it charges $2 per hour, divide $12 by $2 which equals 6 hours.
Answer:
6 hours
Step-by-step explanation:
Cost = fee + charge per hour * number of hours
22 = 10 +2h
Subtract 10 from each side
22-10 = 10+2h-10
12 = 2h
Divide
12/2 = 2h/2
6 = h

>we have the sum of interior angles is
108+108+7y-5+7y-5 = 360, combine like terms
14y +206 =360, subtract 206 from both sides
14y = 154, divide both sides by 14
y= 11
>the sides are congruent therefore
4x+17 = 8x-3 , subtract 4x, and add 3 from both sides

find the outputs.. please help
Answers
Answer:
see below
Step-by-step explanation:
The steps are +2 then *4 then -8 then ÷2
Input is 5
5 +2 =7 *4 = 28-8 = 20 ÷2 = 10 Output is 10
Input is 9
9 +2 =11 *4 = 44-8 = 36 ÷2 = 18 Output is 18
Input is 14
14 +2 =16 *4 = 64-8 = 56 ÷2 = 28 Output is 28
Input is 18
18 +2 =20 *4 = 80-8 = 72 ÷2 = 36 Output is 36
Input is 23
23 +2 =25 *4 = 100-8 = 92 ÷2 = 46 Output is 46
Input is 7.5
7.5 +2 =9.5 *4 = 38-8 = 30 ÷2 = 20 Output is 20
Input is 11.54
11.54 +2 =13.54 *4 = 54.16-8 = 46.16 ÷2 = 23.08 Output is 23.08
Answer:
Output:
5 + 2 x 4 - 8 ÷ 2 = 9
9 + 2 x 4 - 8 ÷ 2 = 13
14 + 2 x 4 - 8 ÷ 2 = 18
18 + 2 x 4 - 8 ÷ 2 = 22
23 + 2 x 4 - 8 ÷ 2 = 27
7.5 + 2 x 4 - 8 ÷ 2 = 11.5
11.54 + 2 x 4 - 8 ÷ 2 = 14.54
The height, h metres, of a springboard diver above the surface of the water t seconds after she leaves the board is given by h=-5t-12+7. Find the maximum height reached by the diver? How long does it take for the diver to reach maximum height? Find the height of the diving board?
Answers
Answer:
[tex]h_{max} = 14.2m[/tex]
[tex]t = 1.2[/tex]
The height of the diver is 7m
Step-by-step explanation:
Given
[tex]h(t) =-5t^2 + 12t + 7[/tex]
Solving (a): The maximum height reached
First, we calculate the time to reach the maximum height using:
[tex]t = - \frac{b}{2a}[/tex] --- maximum of a function
Where
[tex]a = -5; b = 12; c = 7[/tex]
So, we have:
[tex]t = -\frac{12}{-2 * 5}[/tex]
[tex]t = \frac{12}{10}[/tex]
[tex]t = 1.2[/tex]
So, the maximum height is:
[tex]h(t) =-5t^2 + 12t + 7[/tex]
[tex]h(1.2)=-5 * 1.2^2 + 12 * 1.2 + 7[/tex]
[tex]h(1.2)=14.2[/tex]
Hence:
[tex]h_{max} = 14.2m[/tex]
Solving (b): Time to reach maximum height
This has been calculated in (a)
[tex]t = 1.2[/tex]
Solving (c): Height of the board.
This can be calculated by setting [tex]t =0[/tex] --- i.e. the height of the diver before diving
So, we have:
[tex]h(t) =-5t^2 + 12t + 7[/tex]
[tex]h(0) = -5 * 0^2 + 12 * 0 + 7[/tex]
[tex]h(0) = 7[/tex]
