Answer:
14.373 inc.sq
Step-by-step explanation:
Here's your solution
=> Area of cone = πr(r + l)
=> π = 3.14
=> radius = 1.9/2 inc
= l = 4.5 inc
=> putting value in formula
=> Area = 3.14*0.95(0.95 + 4.5)
=> Area = 2.983*5.45
=> Area of cone = 14.373 inc.sq

Using the perimeter formula of a rectangle, P = 21+2w, find the perimeter of the rectangle giver
the length is 42 feet and the width is 26 feet
I
Answer:
-21
Step-by-step explanation:
the formula for the perimeter of a rectangle is 2l+2w. which means twice the length and twice the width added to together.
if you mean this:
x=21+2x
minus x on both sides
0=21-x
add 21 on both sides
21=-x
x=-21
than you subsitute
2×-21=-42
-42+21= -21
The perimeter is than -21

Answer:
72°
Step-by-step explanation:
The external angle E is half the difference of the intercepted arcs.
44° = (CD -DF)/2
88° = CD -DF
DF = CD -88° = 160° -88° = 72°
g Farmer Violet wants to enclose one 990 square foot rectangular area of land using fencing. One side will use special fencing costing $12 per foot. The remaining three sides of fencing will be formed using standard fencing costing $10 per foot. Find the dimensions of the corral that would minimize the cost of the fencing required for this project, rounded (if necessary) to the nearest hundredth of a foot
Answer:
Sides of the rectangular area:
x = 30 f
y = 33 f
Step-by-step explanation:
Let´s call x and y the sides of the rectangular area
A = x*y = 990 y = 990/x
The function cost is:
C = Costs ( sides x) + costs ( sides y )
Cost of sides x = 12*x + 10x
Cost of sides y = 10*y + 10 *y = 2*10*y = 20*y
C = 12*x + 10*x + 20*y = 22*x + 20*y
The function cost as function of x is:
C(x) = 22*x + 20*(990/y) = 22*x + 19800/x
Tacking derivative on both sides of the equation:
C´(x) = 22 + [ - 19800/x²]
C´(x) = 0 22 - 19800/x² = 0
Solving for x
22*x² - 19800 = 0
22x² = 19800
x² = 19800/22 = 900
x₁,₂ = ± 30 We dismiss negative root ( we never have negative lenghts)
Then x = 30 f
And y = 990 / 30 y = 33
To see if x = 30 is a minimum for function C(x) we evaluate the second derivative.
C´´(x) = 2*x* 19800/x⁴
C´´ (x) = 39600/x³ so C´´ is always greater than 0 then C (x) has a minimum at x = 30
Sides of the rectangular area are:
x = 30
y = 33

Answer:
x = 9y = 45z = 9 root 2Step-by-step explanation:
In this isosceles right triangle, the acute angles are equal and the side lengths have the ratios 1 : 1 : √2
y° = 90° -45° = 45°
9 : x : z = 1 : 1 : √2 = 9 : 9 : 9√2
x = 9; z = 9√2

What is the distance you are standing from the base of the tree?
Answer:
c = 12.5903 as it is more accurate
Step-by-step explanation:
tan65 = 27/d , value of tan65 is 2.1445
2.1445 = 27/d
d = 27/2.1445
d = 12.5903
so answer would be c as it is more accurate than others.
5. State the slope and y-intercept of the line 2x + y + 1 = 0.
Answer:
2x+y+1=0
Step-by-step explanation:
this is a first degree equation with two unknown variables, x and y. they are referred to as linear equation and are typically represented in slope intercepts form, y=mx+b, where m is the slope of the line and b is the y intercept. So you want to set the equation equal to y by isolating it to one side of the equation.
Subtract all term other than y (in this case, 2x and 1) from both sides of the equation.
2x+y+1-2x-1=0-2x-1
y=-2x-1
Answer:
M=-2 & C=-1
Step-by-step explanation:
2x+y+1=0
The equation of a straight line is given as
y=mx+c
where, m is the gradient slope
c is y- intercept
from the equation 2x+y+1=0
make y subject of the formula
2x+y+1=0
y= -2x-1
Therefore, Slope (M)=-2 & y-intercept (c)=-1
