Answer:
55
Step-by-step explanation:
This is the equation of a parabola. To make things simpler, we can replace [tex]h[/tex] with [tex]y[/tex] and [tex]t[/tex] with [tex]x[/tex]. Therefore, [tex]y=-5x^2+30x+10[/tex]. Because the coefficient of the [tex]x^2[/tex] term is negative, we know the parabola points down, and the maximum height is the vertex. The x coordinate of the vertex of a parabola can be found with the equation [tex]-\frac{b}{2a}[/tex], or [tex]-\frac{30}{-10} = 3[/tex]. Plugging in [tex]3[/tex] into the equation gives us [tex]y = -5(3)^2+30(3)+10 = \boxed{55}[/tex]

Which equation represents the graph shown?
Step-by-step explanation:
The graph is a linear equation starting at 0.
form y = mx + b.
starts at 0, so b = 0, so the 2nd and 3rd choices are incorrect.
change in y/change in x is the slope,
and you can see it goes up about 35 in the y direction for every 1 in the x, so the slope is 35.
so it's the first answer.
The linear equation of the graph is y = 35x. So, the option first is correct.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form y = mx + b.
The graph is a linear equation origin at 0.
Since b = 0, the 2nd and 3rd choices are incorrect.
The slope = change in y/change in x
Here, we can see that it goes up about 35 in the y-direction for every 1 unit of in the x, so the slope is 35.
so the first answer is correct which is y = 35x.

four pumpkins weigh 26 pounds altogether. Pumkin one weighs four less than three times the weight of Pumkin threee. Pumkin four weighs twice as much as pumkin One. Pumpkin Two weighs five more pounds than Pumkin three. What does each pumpkin weigh
Answer:
5, 8, 3, 10 lbs.
Step-by-step explanation:
We can solve this using a system of equations! We will call pumpkins [tex]a, b, c, d[/tex].
Our equations are thus:
[tex]a + b + c + d = 26[/tex]
[tex]a = 3c - 4[/tex]
[tex]d = 2a[/tex]
[tex]b = c + 5[/tex]
So now we just need to solve this system of equations.
We can start by solving for the value of pumpkin [tex]c[/tex] and go from there. So first we substitute some equations around.
First we write out pumpkin [tex]d[/tex] in terms of [tex]a[/tex].
[tex]d = 2a = 2(3c - 4) = 6c - 8[/tex]
And now we put the three equations into the first equation:
[tex]a + b + c + d = 26\\(3c-4)+(c+5)+(c)+(6c-8)=26[/tex]
Then we simplify to get:
[tex]11 c - 7 = 26[/tex]
[tex]11c = 33\\c = 3[/tex]
So we know pumpkin [tex]c[/tex] weighs 3 pounds.
Then we use the equations from before to get the value of the other pumpkins:
[tex]a = 3c-4 = (3*3)-4=9-4=5\\d = 2a = 2*5=10\\b = c + 5 = 3 + 5 = 8[/tex]
And we can check our results by putting into first equation:
[tex]5+8+3+10=26[/tex]
So it works out!
Thus our pumpkins weigh 5, 8, 3, 10 lbs each.
Mary is twice as old as Helen’s age, If 8 is subtracted from Helen’s Age and 4 is added to Mary Age? Mary will be 4 times as old as Helen. What are the ages
Answer:
set mary is x years old, and helen is y years old.
first sentence:x=2y
second one:4(y-8)=x+4
bring x=2y in 4(y-8)=x+4
=>4y-32=2y+4
=>2y=36
=>y=18
=>x=36
mary:36
helen:18
We want to write and solve a system of equations that models given situation. We will see that Helen is 18 years old, and Mary is 36 years old.
Let's define the variables we will be using.
m = Mary's age.h = Helen's age.We know that "Mary is twice as old as Helen’s age"
Then:
m = 2*h
"If 8 is subtracted from Helen’s Age and 4 is added to Mary Age, Mary will be 4 times as old as Helen."
(m + 4) = 4*(h - 8)
Then the system of equations is:
m = 2*h
(m + 4) = 4*(h - 8)
To solve it, we can replace m by 2*h in the second equation, so we get:
(2h + 4) = 4*(h - 8)
2*h + 4 = 4*h - 32
4 + 32 = 4*h - 2*h
36/2 = h = 18
And we know that:
m = 2*h = 2*18 = 36
So Helen is 18 years old, and Mary is 36 years old.

Calculate the directional derivative of f(x, y) = cot-'(xy) in the direction of v = -4i + 5j at the point P = (0.5, 0.5).
Remember to normalize the direction vector.
DS(0.5, 0.5) =
Looks like f(x, y) = cot⁻¹(xy), as in the inverse cotangent.
If you're like me and you don't remember the derivative of the inverse trig functions, we can derive it as follows. Let y = cot⁻¹(x), so that for appropriate x we can write cot(y) = x. By the chain rule, differentiating both sides gives
-csc²(y) y' = 1
y' = -sin²(y) = -sin²(cot⁻¹(x)) = - 1 / (x² + 1)
Next, recall that the derivative of a function f(x, y) at a point (a, b) in the direction of a vector v is given by
∇ f(a, b) • v
Compute the gradient ∇ f(x, y) :
∇ f(x, y) = - y / ((xy)² + 1) i - x / ((xy)² + 1) j
At the point P, we have
∇ f(x, y) = - 8/17 i - 8/17 j
So, the derivative of f at P along v = - 4 i + 5 j is
(- 8/17 i - 8/17 j) • (- 4 i + 5 j) = - 8/17

Answer:
(-1,0)
Step-by-step explanation:
Answer:
(-1, 0)
Step-by-step explanation:
The x-axis is the horizontal line in bold. It's basically asking what points in the form (x,y) are touching said line.
So we use our eyes and determine that the line intercepts the x-axis at -1 because that vertical bold line is the y-axis and it determines that the left side of the graph is negative and the right side is positive.
Since it is an x-intercpet, when the y-value is 0 the y-term in
(x,y) is 0
and the x-term would be the -1

"Simplify" in this context means "combine like terms." It can help to group the terms with the same variables.
-9x+9x^2+8x^2+4x
= 9x^2 +8x^2 -9x +4x
= x^2(9+8) +x(-9+4)

Solve for x. 4(x+1)= -3x-10
Answer:
4x+4=-3x-10
4x+3x=-10-4
x= -14
Step-by-step explanation:
Answer:
x = -2
Step-by-step explanation:
P.E.M.D.A.S
4(x + 1) = 4x+4
now we have 4x + 4 = -3x - 10.
now we can combine like terms which are x
4x and -3x, to combine like terms we can either subtract 4x on both sides or -3x on both sides, but lets do 4x.
now we have this
4x + 4 = -3x - 10.
-4x -4x
= 4 = -7x - 10
now we can isolate x by its self so we have to add 10 on both sides
4 = -7x - 10
+10 +10
and we get
14 = -7x
now we can divide -7 to get x by its self
14/-7 = -7/x
we get for our final answer
x = -2

How many feet are in 120 inches?
Enter your answer in the box.
ft
The required converted value is 10 feet, which is 120 inches into feet.
As we know that unit conversion is the process of converting a quantity from one unit of measurement to another. It refers to multiplying the given quantity by a conversion factor that blends the two proportional units.
To convert inches to feet, we use the conversion factor:
1 foot (ft) = 12 inches (in)
Therefore, to convert 120 inches to feet, we divide by the conversion factor:
120 inches / 12 in/ft = 10 feet
So, there are 10 feet in 120 inches.
