Step-by-step explanation:
A fireboat in the harbor is helping put out a fire in a warehouse on the pier. The
distance from the barrel (end) of the water cannon to the roof of the warehouse is
120 feet, and the water shoot up 50 feet above the barrel of the water cannon.
Write a function that models the path of the water.
The answer is "parabola [tex]y =-0.0139(x-60)^2+50[/tex]", and the further calculation can be defined as follows:
Let's all describe the circumstance in an XY plane and then let the origin (0,0) indicate the parabola's initial point.The last point now, so because the diameter of the parabola is 120 feet (120, 0).It is stated that, as a result of the water shots at 50 feet just above the cannon barrel, the vertex of such a parabola shall be, as shown in the picture below, (60, 50) as a parabola is a symmetric figure.Now, we know (h,k) that the general parabolic equation[tex]y = a(x-h)^2+k[/tex][tex](h,k)=(60, 50)[/tex] the equation will thus be [tex]y=a(x-60)^2+50[/tex]Since we assume, the graph, therefore, crosses from point [tex](0,0)[/tex][tex]y =a(x-60)^2+50\\\\0=a(0-60)^2 + 50\\\\0 = 3600a + 50 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{(subtract 50 from both sides)}\\\\0 - 50 = 3600a + 50 - 50\\\\-50=3600a \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{(divide both sides by 3600)}\\\\\frac{-50}{3600}=\frac{3600 a}{3600} \\\\-0.0139 \approx a \\\\a \approx -0.0139[/tex]
Therefore, the equation of the given parabola is [tex]y =-0.0139(x-60)^2+50[/tex]

Use the diagram 3 and 4 complementary 1.True 2.False
Answer:
False
Step-by-step explanation:
Complementary means the angles add up to a sum of 90⁰ and 3 and 4 add up to 180⁰ (considering the angles added together make a flat line and a flat line is 180⁰)
a sum of two angles that's add up to 180⁰ is what we call supplementary.

Lisa is standing on a dock beside a lake. She drops a rock from her hand into the lake. After the rock hits the surface of the lake, the rock's distance from the lake's surface changes at a rate of −2 inches per second. If Lisa holds her hand 5 feet above the lake's surface, how far from Lisa's hand is the rock 4 seconds after it hits the surface?
Answer:
5 ft 8 in or 68 inStep-by-step explanation:
In 4 seconds the rock will be at:
2*4 = 8 in from the surfaceAdd 5 feet to this to get the required distance:
5 ft + 8 in = 5*12 in + 8 in = 68 inDistance after 8s:-

You can easily imagine a circle around your graphic. And then you remember that a circle has a total of 360 degrees all the way around the center.
This means that the following sum 4x + 2x + 3x = 360
⇔ 9x = 360
We divide both side by 9 and we get :
⇔ x = 360 / 9 = 40
So X value is 40°.

Calculate the straight line distance between the points (-10, -7) and (-8,1).
G.2(B)
Answer:
2√(17) or about 8.2462 units.
Step-by-step explanation:
We want to determine the distance between the two points (-10, -7) and (-8, 1).
We can use the distance formula. Recall that:
[tex]\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Substitute and evaluate:
[tex]\displaystyle \begin{aligned} d &= \sqrt{((-10)-(-8))^2 + ((-7) - (1))^2} \\ \\ &=\sqrt{(-2)^2+(-8)^2} \\ \\ &= \sqrt{(4) + (64)} \\ \\ &= \sqrt{68}\\ \\ &= 2\sqrt{17}\end{aligned}[/tex]
Hence, the distance between (-10, -7) and (-8, 1) is 2√(17) units or about 8.2462 units.

Solve for the value of v.
Answer:
9
Step-by-step explanation:
Since it is a straight line, therefore it will always be 180°
So...
(8v +3) +105 = 180
8v + 3 + 105 = 180
8v = 180 - 108
V = 72/8
= 9
Answer:
[tex]\boxed {\boxed {\sf v=9}}[/tex]
Step-by-step explanation:
In the diagram, there are 2 angles: 105° and (8v+3)°. They are on a straight line together, so they are supplementary angles. They must add to 180 degrees. We can set up an equation.
[tex]105 + (8v+3) = 180[/tex]
We are solving for v, so we must isolate the variable. First, we can rearrange the right side and combine the like terms (the constants without a variable).
[tex]105 +8v+3= 180 \\8v + (105+3) = 180 \\8v + 108= 180[/tex]
108 is being added to 8v. The inverse operation of addition is subtraction. Subtract 108 from both sides of the equation.
[tex]8v+108-108= 180-108 \\8v= 180-108 \\8v=72[/tex]
v is being multiplied by 8. The inverse operation of multiplication is division. Divide both sides by 8.
[tex]\frac {8v}{8}= \frac{72}{8}\\[/tex]
[tex]v= \frac{72}{8}[/tex]
[tex]v=9[/tex]
v is equal to 9.
