Answer:
8/15
Step-by-step explanation:
you first want to change your whole number, 4, into a fraction so all you have to do is add a 1 in the denominator so it will be 4/1
then you multiply across
2/15 * 4/1
you first multiply 2 and 4 and your answer will be 8 which is the numerator
then multiply 15 and 1 which is 15, the denominator
then you get
8/15
the depth of water at the end of a boat dock can be modeled by a senusoidal function Y=Asin [B(r+C) ]+D where y represents the depth in feet of the water, hours after midnight on a certain day, the depth is 10 feet at low tide at 6 am and 18 feet at high tide at noon find the amplitude and midline for the general sine function that can be used to model the water's depth.
Answer:
A=4 ft
Midline: y=14
Step-by-step explanation:
When talking about sinusoidal waves, we know the amplitude will be the distance between the midline and the highest or lowest point of the graph. This can be found by first, finding the distance between the lowest point and the highest point:
d= 18ft - 10ft = 8ft
and divide this distance into 2:
[tex]A=\frac{8}{2}[/tex]
A= 4 ft
in order to find the midline, we need to figure the midpoint between the highest and lowest value. We can do so by using the following formula:
[tex]Midpoint=\frac{high+low}{2}[/tex]
so:
[tex]Midpoint=\frac{18+10}{2}[/tex]
Midpoint = 14
so the midline is located at the line:
y=14

In ΔNOP, the measure of ∠P=90°, the measure of ∠O=37°, and PN = 72 feet. Find the length of OP to the nearest tenth of a foot.
Answer:
119.6
Step-by-step explanation:
Remark
Draw a rough sketch of what is given.
You will find the NP is the side opposite of the triangle.
P is the right angle
OP is the hypotenuse.
Given
NP = 72
<O = 37
Equation
Sin(O) = NP/OP
Sin(72) = .6018
0.6018 = 72/OP Multiply both sides by OP
0.6018*OP = 72 Divide both sides by 0.6018
OP = 72/0.6018
OP = 119.6

Answer:
Step-by-step explanation:
The chords, when cut anywhere along their length so that there is one intersection point, will produce the following relationship for this question.
(w + 6)*4 = 16*10 Remove the brackets
4*w + 24 = 160 Subtract 24 from both sides
4w = 160 - 24 Combine the right
4w = 136 Divide by 4
w = 136/4
w = 34

The ratio of the measures of the sides of a triangles is 9:7:3. If the perimeter of the triangle is 266 inches, find the value of x
Answer: Depends on which side x is...
Step-by-step explanation:
This is my strategy for finding the values using ratios
Add the ratio together: 9 + 7 + 3 = 19
Divide the perimeter by the sum of the ratio: 266/19 = 14
Now we know what a unit of one is on the ratio: 14
Multiply this unit by the ratio amount
Side with ratio 9: 9 × 14 = 126 inches
Side with ratio 7: 7 × 14 = 98 inches
Side with ratio 3: 3 × 14 = 42 inches

In the diagram mz3= x+ 30 and mz4 =2x-80. What is the measure of angle 3?
Given:
Consider the below figure attached with this question.
[tex]m\angle 3=(x+30)^\circ[/tex] and [tex]m\angle 4=(2x-80)^\circ[/tex].
To find:
The measure of angle 3.
Solution:
From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.
We know that, vertically opposite angles are always equal. So,
[tex]m\angle 3=m\angle 4[/tex]
[tex](x+30)^\circ=(2x-80)^\circ[/tex]
[tex]x+30=2x-80[/tex]
[tex]x-2x=-30-80[/tex]
[tex]-x=-110[/tex]
[tex]x=110[/tex]
Now,
[tex]m\angle 3=(110+30)^\circ[/tex]
[tex]m\angle 3=140^\circ[/tex]
Therefore, the measure of angle 3 is 140 degrees.

(4,0)
Oy-x-1
Oy-1
45
o,-1)
Answer:
the third option is the answer, y= 1/4x-1
Step-by-step explanation:
graph line in standard form:
[tex]y = mx + c[/tex]
where m = slope and c = y-intercept
1) find the slope
slope formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
use the two coordinates given in the graph
i/ (0,-1)
x1 = 0
y1 = -1
ii/ (4,0)
x2 = 4
y2 = 0
substitute the values into the formula
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] \frac{0 - ( - 1)}{4 - 0} [/tex]
[tex] \frac{1}{4} [/tex]
thus, m = 1/4
2) find the y-intercept
* y-intercept is the value of y that cuts through the y-axis
based on the graph, the y-intercept is -1
thus, c = -1
3) substitute the value of m and c into the standard form formula
[tex]y = mx + c[/tex]
[tex]y = \frac{1}{4} x - 1[/tex]
