Part C Next, find the length of BC place point F at (4,4) and draw BF and FC now you hav the right ∆BFC with BC as the hypotenuse find BC and FC ising the coordinates of B,C, and,F then use the Pythagorean theorem to find BC show your work need help ASAP giving thanks and points away I just need these answer fast ???
Answer:
BF = |4 – 1| = 3
FC = |4 – 0| = 4
Using the Pythagorean Theorem to find BC:
BC2 = BF2 + FC2
BC2 = 32 + 42
BC2 = 9 + 16
BC = sqaure root 25
BC = 5
Step-by-step explanation:
The length of BC is 5 unit.
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
We need to find the length of BC place point F at (4,4) and draw BF and FC now you have the right ∆BFC with BC as the hypotenuse find BC and FC using the coordinates of B,C, and,F then use the Pythagorean theorem to find BC.
Using the Pythagorean Theorem to find BC:
BC^2 = BF^2 + FC^2
BC^2 = 32 + 42
BC^2 = 9 + 16
BC = √25
BC = 5
So, BF = |4 – 1| = 3
FC = |4 – 0| = 4

no solution, one solution or infinitely many solutions?
Answer:
3(4p-2) + 3= 2p-5
12p-6 +3 = 2p-5
10p-3=-5
10p=-2
p=-1/5
There is one solution.
hope this helps!
Answer:
one solution
-0.2
Step-by-step explanation:
3(4p - 2) +3 = 2p - 5 Remove the brackets on the left
12p - 6 + 3 = 2p - 5 Combine
12p - 3 = 2p -5 Subtract 2p from both sides
12p - 2p - 3 = -5 Combine
10p - 3 = - 5 Add 3 to both sides
10p = -5 + 3
10p = - 2 Divide by 10
p = - 0.2
Evaluate ∫4x cos(2-3x)dx
Answer:
[tex]{ \sf{ \int 4x \cos(2 - 3x) dx = {4x}^{2} \cos(2 - 3x) + c }}[/tex]
Step-by-step explanation:
From integration by parts:
[tex]{ \boxed{ \bf{ \int u \: \frac{dv}{dx} = uv - \int v \: \frac{du}{dx} }}}[/tex]
let u be cos(2-3x) and let dv/dx be 4x:

Surface Area of Cylinders
Radius = 10ft
Height = 6ft
The area of most three-dimensional geometric shapes is
A = a · h
Area = area of the base · height of the figure.
In this case, the area of the base is the area of a circle, so a = πr²:
a = 10²π
a = 100π ≅ 314
Now, all we have to do is multiply the area of the base to the height:
A = 100π · 6
A = 600π ← In terms of "π"
A ≅ 1884 ← Rounded answer

Darias bought 5 school binders that cost $8.00 per
binder. If a back-to-school discount of 40% was
applied to his purchase, and then a 6% sales tax was
added, what was the total cost of the binders?
Answer:
$25.44
Step-by-step explanation:
First, you multiply, 5*8 = $40.00
Then you subtract the discout, 40-40% = $24.00
Lastly, you must add the sales tax, 24+6% = $25.44
The total cost of the binders is $25.44

Step-by-step explanation:
The distance between the center are the foci located 8 units.
It is required to find the focus is c.
What is ellipse?A closed plane curve generated by a point moving in such a way that the sums of its distances from two fixed points is a constant.
Given that:
The length of the major axis is 2a,
length of the major axis
2a=10
a=5
The length of the minor axis is 2b.
Length of the minor axis
2b=6

The distance between the center and either focus is c,
c^{2} =a^{2} -b^{2}
c^{2} =5^{2} -3^{2}
c^{2} =25-9
c=8

Answer:
[tex]n=10[/tex]
Step-by-step explanation:
[tex]\frac{4^8}{(4^2)^-^3}\ / 4^4=4^n[/tex]
Simplify, remember, an exponent raised to the power of another exponent is equal to the product of the two exponents,
[tex]\frac{4^8}{(4^2)^-^3}\ / 4^4=4^n[/tex]
[tex]\frac{4^8}{4^-^6}\ / 4^4=4^n[/tex]
Now bring the term in the denominator (number under the fraction bar) to the numerator (number over the fraction bar). This can be done by multiplying the exponent of the denominator by (-1).
[tex]\frac{4^8}{4^-^6}\ / 4^4=4^n[/tex]
[tex]4^8(4^(^-^1^)^(^-^6^))\ / 4^4=4^n[/tex]
Simplify,
[tex]4^8(4^6)\ / 4^4=4^n[/tex]
Remember, multiplying two numbers of the same base is the same as adding their exponents, apply this property here,
[tex]4^8(4^6)\ / 4^4=4^n[/tex]
[tex]4^1^4\ / 4^4=4^n[/tex]
Dividing two numbers of the same base is the same as subtraction their exponents,
[tex]4^1^4\ / 4^4=4^n[/tex]
[tex]4^1^0=4^n[/tex]
Thus, the following statement can be made,
[tex]4^1^0=4^n[/tex]

Option A
Graph Inequalities
From the given graph, the curve with the shaded dot shows less than or equal to because the dot indicates that the maximum input value of x is at that point.
Secondly, the curve without a shaded dot shows that the input function of x is only greater than 3.
Looking at the options, option A is right and we will prove it thus;
for y = x³ - 3
At x = 2, we see that;
y = 2³ - 3
y = 5
This corresponds with the given equation
For the second curve, for y = x² + 6;
At x = 2, we have;
y = 2² + 6
y = 4 + 6
y = 10
This corresponds with what is given and is thus correct.

Answer:

Step-by-step explanation:
This illustrates the Remainder Theorem. If a polynomial f(x) is divided by x−a , the remainder is the constant f(a) , and f(x)=q(x)⋅(x−a)+f(a) , where q(x) is a polynomial with degree one less than the degree of f(x) . Synthetic division is a simpler process for dividing a polynomial by a binomial.
