Answer:
Below
Step-by-step explanation:
f(t) = 4.1 (sin pi/6 t - pi/3) + 19.7 <===will be a maximum when the sin portion is equal to 1
so sin ( pi/6 t - pi/3) = 1 given that sin is equal to one at 0 and pi and 2 pi and 3 pi and 4 pi etc
pi/6 t - pi/3 = 0 or pi , 2 pi, 3 pi , 4 pi
then t = 2 and 8 and 14 and 20 hrs ( every 6 hrs starting with t = 2)

5) A = 1561.4906, C = 140.044
6) A = 994.8776, C = 111.784
Step-by-step explanation:
1)
[tex]A = \Pi (\frac{D}{2})^2 = 3.14 * (\frac{26.4}{2})^2 = 3.14 * 13.2^2 = 547.1136[/tex]

[tex]A = \Pi (\frac{D}{2})^2 = 3.14 * (\frac{44.5}{2})^2 = 3.14 * 22.25^2 = 1554.49625[/tex]
[tex]C = \Pi D = 44.5*3.14 = 139.73[/tex]
5)
[tex]A = \Pi r^2 = 3.14*22.3^2 = 1561.4906[/tex]
[tex]C = 2\Pi r = 2 * 3.14 * 22.3 = 140.044[/tex]

What is a lap?When a driver or a runner makes one trip around the track i.e. one full circle it is called lap.
Given a lap around a track is 2/5 of a mile.
1 lap =2/5 mile
x lap = 11/2 mile
x lap =(11/2) ÷(2/5)

In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 7 times out of 10 attempts. Tasha has hit the ball 10 times out of 16 attempts. Which player has a ratio that means they have a better batting average?
Tasha, because she has the lowest ratio since 0.7 < 0.625
Tasha, because she has the highest ratio since 56 over 80 is greater than 50 over 80
Jana, because she has the highest ratio since 56 over 80 is greater than 50 over 80
Jana, because she has the lowest ratio since 0.7 < 0.625
Answer: The correct answer is C. Jana has a higher ratio of hits to total attempts, so she has a better batting average. This can be calculated by dividing the number of hits by the number of attempts: Jana's batting average is 7/10 = 0.7, and Tasha's batting average is 10/16 = 0.625. Since 0.7 is greater than 0.625, Jana has a higher batting average.

Given:
The figure of a rhombus.
To find:
The measure of angle 1.
Solution:
First label the vertices of the rhombus as shown in the below figure.
We know that the opposite angles of a rhombus are congruent and the diagonals of a rhombus bisect each vertex angle.
[tex]m\angle ABD=m\angle CBD=30^\circ[/tex] (Diagonal BD is the angle bisector)
Now,
[tex]m\angle ABC=m\angle ABD+m\angle CBD[/tex]
[tex]m\angle ABC=30^\circ+30^\circ[/tex]
[tex]m\angle ABC=60^\circ[/tex]
We know that the consecutive angles of a rhombus are supplementary. It means the sum of each pair of consecutive angles is 180 degrees.
[tex]m\angle BAD+m\angle ABC=180^\circ[/tex]
[tex]m\angle 1+60^\circ=180^\circ[/tex]
[tex]m\angle 1=180^\circ-60^\circ[/tex]
[tex]m\angle 1=120^\circ[/tex]
Therefore, the measure of angle 1 is [tex]m\angle 1=120^\circ[/tex].

The measurement of the hypotenuse is obtained as 9 units using the Pythagoras theorem.
What is Pythagoras Theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.
According to the graph -
The perpendicular measures 4 units.
The base measures 3 units.
To find the hypotenuse g apply the Pythagoras theorem -
(hypotenuse)^2=(base)^2+(perpendicular)^2
(g)^2=(3)^2+(4)^2
(g)^2=9+16
(g)^2=25
g=[tex]\sqrt{25}[/tex]
g=5
Therefore, line segment g measures 5 units.

Answer pls! I hope this isn't too hard.
Answer:
8⁶/8⁻⁵8¹¹Step-by-step explanation:
When increasing the power of an integer by another power, you should multiply both powers to find the total power that the integer should be raised to. In this case therefore:
= 3 * 2
= 6
So the numerator will be 8⁶
When dividing the same integers raised to powers, you should subtract the power of the divisor from the power number being divided.
In this case therefore, you are to subtract (-5) from 6 (calculated in first part).
= 6 - (-5)
= 6 + 5
= 11
Another way of writing the above will therefore be: 8¹¹.

Answer:
x = 12 and y = 11
Step-by-step explanation:
4x+3y=-15 -----equation 1st
4x-y = -27 ____equation 2nd
then,
Multiple equation second by 3 and slove it with equation first
4X +3Y = -15
12X -3Y = -81 (Multiples it with 3)
-8x = -96 (subtracted)
x=-96/-8
therefore, x=12
again,
from equation first
4x+3y = -15
or 4 × 12 + 3y = -15
or 3y = -15+48
or 3y= 33
or y=33/3
therefore, y =11

Answer:
x = -6, y = 3
Step-by-step explanation:
1) 4x + 3y = -15
2) 4x - y = -27
0 + 4y = 12 subtract equation (2) from equation (1)
4y = 12
y = 12/4 = 3 substitute y = 3 into either equation 1 or 2 and solve for x
4x + 3(3) = -15
4x = -24
x = -6
Check your answers by plugging x = -6, y = 3 into the equations:
4(-6) + 3(3) = -15 correct!
4(-6) - 3 = -27 correct!

b) p= 70
Step-by-step explanation:
Substitute the equation with the given value and solve the equation to arrive at the answer.
Q1. a) q= 4 +0.8p
When p= 7,
q= 4 +0.8(7)
q= 4 +5.6
q= 9.6
b) q= 4 +0.8p
When p= 100,
q= 4 +0.8(100)
q= 4 +80
q= 84
Q2. a) q= 4 +0.8p
When q= 12,
12= 4 +0.8p
0.8p= 12 -4 (-4 on both sides)
0.8p= 8
p= 8 ÷0.8 (÷0.8 on both sides)
p= 10
b) q= 4 +0.8p
When q= 60,
60= 4 +0.8p
0.8p= 60 -4 (-4 on both sides)
0.8p= 56
p= 56 ÷0.8 (÷0.8 on both sides)
p= 70

Plot and connect the points A(-6, 2), B(3, -6), C(-6, -6), and find the area of the triangle formed.
A.
36 square units
B.
72 square units
C.
4 square units
D.
12.5 square units
Answer:
A
Explanation:
If you graph the points and connect them, you'll see the triangle they're asking about. Yhe base of the triangle is 9 and the height is 8. The area of a triangle is half of the base times the height. So multiply 8 by 9 and you get 72. This is twice the area. So divide it by 2 and you get 36, which is the area of the triangle. So the answer is A.
