Answers
Answer:
2.25 -0.25 increasing (-0.25,2.25)
Step-by-step explanation:
The minimum and maximum values are negative 1/4 and 9/4. In the interval of (0, π/2), the function is decreasing. And the range of the function will be [–1/4, 9/4].
What is a sinusoidal Function?It is a function that repeats itself in a particular time interval.
The equation is given as
y = A sin (ωx + Ф) + C
Where A is the amplitude, ω is the frequency, Ф is the phase difference, and C is the constant.
The function is given below.
f(x) = (5/4) sin(x) + 1
Compare the function with standard equation.
A = 5 / 4
ω = 1
Ф = 0
C = 1
Then the maximum value of the function at sin x = 1, will be
Maximum value = 5/4 + 1
Maximum value = 9/4
Then the minimum value of the function at sin x = –1, will be
Minimum value = –5/4 + 1
Minimum value = –1/4
In the interval of (0, π/2), the function is decreasing.
And the range of the function will be [–1/4, 9/4].

Solve the system of equations 3x+2y=223x+2y=22 and -4x+3y=16−4x+3y=16 by combining the equations.
Answers
Answer:
(2, 8)
Step-by-step explanation:
Given the system of equation
3x+2y=22 ... *4
-4x+3y=16 .... *3
Using the elimination method
12x + 8y = 88
-12x + 9y = 48
Add
8y + 9y = 88+48
17y = 136
y = 136/17
y = 8
Recall that
3x+2y=22
3x+2(8)=22
3x + 16 = 22
3x = 22-16
3x = 6
x = 6/3
x = 2
Hence the required solution (x, y) is (2, 8)

From the top of a light house 60 meters high with its base at sea level, the angle of depression to a boat is 15o. What is the distance of the boat from the foot of the light house?
Answers
Answer:
Distance between boat and light house = 223.88 meter (Approx.)
Step-by-step explanation:
Given:
Height of light house = 60 meters
Angle of depression to boat = 15°
Find:
Distance between boat and light house
Computation:
Using trigonometry application:
Tanθ = Perpendicular / Base
Tan 15 = Height of light house / Distance between boat and light house
0.268 = 60 / Distance between boat and light house
Distance between boat and light house = 60 / 0.268
Distance between boat and light house = 223.88 meter (Approx.)

Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r = 6 ÷ - 2 = - 18 ÷ 6 = 54 ÷ - 18 = - 3
This indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 2 and r = - 3 , then

What was the median price of the items?
MEAN AND MEDINA
Answers
Answer:
Mean is 5.2 Median is $6.00
Step-by-step explanation:
To find mean u have to find the "average" whereby u add all the numbers and divide by the number of numbers.
($2+$4+$6+$6+$8)= $26. Then since there are 5 numbers in all u divide by 5.
$26÷5 =5.2 5.2 is the median.
Median is the middle number. To find it u have to rearrange the numbers from smallest to largest and find the middle number.
$2, $4, {$6,} $6, $8
$6 is the median.

A biologist was sitting near a pond and noticed a large number of dragonflies. He also saw both frogs and fish trying to eat the
dragonflies. He counted a total of 89 fish, frogs, and dragonflies. He noticed that there were four times as many dragonflies as fish and
that the frogs were five more than twice the number of fish
Answers
89 /3
frogs = 29.6
fish = 29.6
dragonflies = 29.6
all of them equal 89
a = fish = 12
b = frog = 29
c = dragonflies = 48
a + b + c = 89
c = 4a (four times as many dragonflies as fish)
b = 2a + 5 (frogs were five more than twice the number of fish)
Then substitute for b and c in the big equation:
a + (2a + 5) + 4a = 89
Combine like terms:
7a + 5 = 89
Subtract 5 from both sides:
7a = 84
Divide both sides by 7:
a = 12
Now use this to solve for b and c
c = 4(12) = 48
b = 2(12) + 5 = 24 + 5 = 29
Please let me know if you have any questions.

$100 are shared between Adam and Hamza in the ratio 1:3.
A)
How many dollars did Adam receive?
How many dollars did Hamza receive?
Answers
Answer:
$25 for Adam and $75 for Hamza
Step-by-step explanation:
$100 will be divided to 3 + 1 = 4 parts
the dollars Adam received
= $100 × 1/4
= $25
the dollars Hamza received
= $100 × 3/4
= $75
-----------------------------------------------------------
the dollars Hamza give to Adam
= $75 × 25%
= $75 × 25/100
= $18.75
the dollars Adam have
= $25 + $18.75
= $43.75
the dollars Hamza have
= $75 - $18.75
= $56.25
the ratio
= 43.75：56.25
= 7：9
