Answer:
The equation in the standard form is
[tex]y+2x=5[/tex]
Step-by-step explanation:
Given the points
(6, -7)(4, -3)Finding the slope between (6, -7) and (4, -3)
[tex]\left(x_1,\:y_1\right)=\left(6,\:-7\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-3-\left(-7\right)}{4-6}[/tex]
[tex]m=-2[/tex]
As the point-slope form is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -2 and the point (6, -7)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-7\right)=-2\left(x-6\right)[/tex]
Writing the equation in the standard form form
As we know that the equation in the standard form is
[tex]Ax+By=C[/tex]
where x and y are variables and A, B and C are constants
converting the equation in standard form
[tex]y-\left(-7\right)=-2\left(x-6\right)[/tex]
[tex]y+7=-2\left(x-6\right)[/tex]
subtract 7 from both sides
[tex]y+7-7=-2\left(x-6\right)-7[/tex]
[tex]y=-2x+5[/tex]
[tex]y+2x=5[/tex]
Therefore, the equation in the standard form is
[tex]y+2x=5[/tex]

Answers
Answer:
[tex]V=5.23\times 10^8\ m^3[/tex]
Step-by-step explanation:
A large water reservoir can be well modeled with a hemisphere whose radius is 630 meters.
The volume of a hemisphere is given by :
[tex]V=\dfrac{2}{3}\pi r^3[/tex]
Substitute r = 630 m in the above formula
[tex]V=\dfrac{2}{3}\pi \times (630)^3\\\\=5.23\times 10^8\ m^3[/tex]
So, the water reservoir can hold [tex]5.23\times 10^8\ m^3[/tex] of water.

Answers
Answer:
[tex]0<p\leq15.5[/tex]
Step-by-step explanation:
Amount of gasoline in the tank is 5.5 gallons
21 gallons is the capacity of the fuel tank in the car
A is the amount of gasoline in the fuel tank after purchase which will be less than or equal to 21 gallons.
So the equation will be
[tex]5.5+p\leq A\\\Rightarrow 5.5+p\leq 21\\\Rightarrow p\leq 21-5.5\\\Rightarrow p\leq 15.5[/tex]
So, the value of p is in the range of [tex](0,15.5][/tex] or [tex]0<p\leq15.5[/tex].
A daredevil decides he wants to jump out of a plane and parachute to the U.S.S. Showboat. He knows he needs to leave the plane at an angle of 58˚ from vertical and he knows he wants to wait until the horizontal distance to the boat is 1000yd. How far away should the plane be from the boat to complete his aerial stunt successfully?
Answers
Answer:
1179 yards
Step-by-step explanation:
The question can be described by a right angled triangle.
The angle of depression of the boat from the plane = [tex]90^{o}[/tex] - 58˚
= [tex]32^{o}[/tex]
Let the distance from the plane to the boat be represented by x.
Thus, applying the appropriate trigonometric function, we have;
Cos θ = [tex]\frac{Adjacent}{Hypotenuse}[/tex]
Cos [tex]32^{o}[/tex] = [tex]\frac{1000}{x}[/tex]
x = [tex]\frac{1000}{Cos 32^{o} }[/tex]
= [tex]\frac{1000}{0.8481}[/tex]
= 1179.11
x = 1179 yds
The plane should be 1179 yards away from the boat.

What is Linear function?The graph of a linear function is a straight line. The following is the form of a linear function. a + bx = y = f(x). One independent variable and one dependent variable make up a linear function. X and Y are the independent and dependent variables, respectively.
Given:
From the graph we can write the points as
(1, 0), (2, 25), (3, 50), (4, 100), (5, 150), (6, 200), (7, 290)
Since from the above points we can see that there is no constant rate of change followed by the points which the graph Curve.

Find the zero of the function.
g(x) = x2 + 22x + 121
The zero of the function is x=
Answers
Answer:
x = -11
Step-by-step explanation:
To find the zero of this function, factor the equation:
g(x) = [tex]x^{2} +22x+121[/tex]
g(x) = (x + 11) (x + 11)
g(x) = [tex](x+11)^{2}[/tex]
The zeros of a function are the values of x that will make g(x) equal 0. So, the zero of this function is -11, because -11 + 11 = 0. So, x = -11.

The total cost, c, in dollars to create calendars for a fundraiser can be found using the function c=5.5u+25 where u is the number of calendars made. If there are at least 10 calendars made, what is a possible domain for this function?
A: 10≤x≤100
B: {-12, -11, 12, 20, 50}
C: {10, 11, 12, 13, 14}
D: 0≤x<50
Answers
Answer:
The correct option is;
{10, 11, 12, 13. or 14}
Step-by-step explanation:
The given function for the total cost, c, to create calendars is c = 5.5u + 25
The domain of a function are the values of the input variables of the function with which the output (the values) of the function are found
Therefore, the domain of the given function are the values of the variable, u, in the function
Where;
u = The number of calendars made
∴ When u ≥ 10, we have;
The possible domain for the function are u = 10, 11, 12, 13. or 14...
Therefore, the correct option is {10, 11, 12, 13. or 14}
Darius took a road trip to their grandmother's house. They drove at a constant speed of 60 miles per hour for 2 hours. They took a break and then finished the rest of their trip driving at a constant speed of 50 miles per hour for 2 hours. What was the total distance, in miles, of Darius' trip?
Answers
Answer: 220 miles
Step-by-step explanation:
Distance travelled is calculated as:
= Speed × Time
Based on the scenario on the question, the total distance, in miles, of Darius' trip will be:
= (60 × 2) + (50 × 2)
= 120 + 100
= 220 miles
