Answer:
125.1 cm^2 to 1 D.P.
Step-by-step explanation:
We could use Heron's formula to do this
Area = √(s(s-a)(s-b)(s-c) ) where s is the semi-perimeter and a b and c are the lengths of the 3 sides
So we have:
s = (17+17+17) / 2 = 25.5
and Area = √(25.5)(25.5 - 17)^3)
= √15660.1875
= 125.14 cm^2
The solution (-4,0) is a solution to which of the following equations? How do you know?
a)3y-x=4
b)10x+1/2y=3
c)-2x-3y=-4
d)-6x+2y=24
Answer:
Correct option is A)
If the solutions to the equations are 8 and −4, the factored form of the equation is : (x−8)(x+4)=0
Use FOIL to find the quadratic form: x

Is kilobyte bigger than megabyte.
Answer:
no
Step-by-step explanation:
1 kilobyte = 1000 byte
1 megabyte = 1,000,000 byte
1 kilobyte = 1/1000 megabyte
Answer: no
Answer:
NO!!!! Kilobyte isn't BIGGER than MegabyteStep-by-step explanation:
Here's the table:
1 Kilobyte = 1,024 Bytes
1 Megabyte = 1,024 Kilobytes
1 Gigabyte = 1,024 Megabytes
1 Terabyte = 1,024 Gigabytes
From the table, we can see that Megabyte is bigger than Kilobyte
If f(x) = 6x-6, find x when f(x) = 36.
Answer:
x=7
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
given f(x) = 6x - 6 and f(x) = 36 , then equating gives
6x - 6 = 36 ( add 6 to both sides )
6x = 42 ( divide both sides by 6 )
x = 7

Verify (x-2) is a factor
of Q(x)=x²-3x²-4x+12
Answer:
(x - 2) is not a factor of Q(x)
Step-by-step explanation:
if (x - h) is a factor pf f(x) then f(h) = 0
if (x - 2) is a factor of Q(x) then Q(2) = 0
Q(2) = 2² - 3(2)² - 4(2) + 12
= 4 - 3(4) - 8 + 12
= 4 - 12 + 4
= - 8 + 4
= - 4
since Q(2) ≠ 0 then (x - 2) is not a factor of Q(x)
However , if the polynomial was meant to be
Q(x) = x³ - 3x² - 4x + 12 , then
Q(2) = 2³ - 3(2)² - 4(2) + 12
= 8 - 12 - 8 + 12
= 0
then (x - 2) is a factor of Q(x) = x³ - 3x² - 4x + 12

A triangle has vertices v (3, 6), n (8,1), and h (1, -1. click on each blank to select a word or phrase to complete the sentence. triangle vnh is because the lengths of are
The triangle VNH is an isosceles triangle because the lengths of sides VH and NH are congruent
How to determine the type of triangle?The coordinates are given as:
V = (3,6)
N = (8,1)
H = (1,-1)
Calculate the distance between each point using:
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
So, we have:
[tex]VN = \sqrt{(8 -3)^2 + (1 -6)^2}[/tex]
[tex]VN = \sqrt{50}[/tex]
[tex]VH = \sqrt{(1 -3)^2 + (-1 -6)^2}[/tex]
[tex]VH = \sqrt{53}[/tex]
[tex]NH = \sqrt{(8 -1)^2 + (1 +1)^2}[/tex]
[tex]NH = \sqrt{53}[/tex]
Notice that two sides of the triangle are equal.
Hence, the triangle VNH is an isosceles triangle

write y=x^2-6x+17 in vertex form. step by step
Step-by-step explanation:
the general vertex form is
y = a(x - h)² + k
with (h, k) being the vertex.
after doing all the multiplications we get
y = a(x² - 2hx + h²) + k = ax² - 2ahx + ah² + k
our original equation is
y = x² - 6x + 17
and now we simply compare the cording parts :
ax² = x²
a = 1
-2ahx = -2hx = -6x
-2h = -6
h = -6/-2 = 3
ah² + k = 17
3² + k = 17
9 + k = 17
k = 8
so the vertex form is
y = (x - 3)² + 8

Answer:answer to 9:$1,025.00 answer to 10:$243.90 answer to 11:$1,025.15
Step-by-step explanation:
explanation to 9:First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year.
Solving our equation:
A = 500(1 + (0.07 × 15)) = 1025
A = $1,025.00
The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 7% per year for 15 years is $1,025.00.explanation to 10:First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year.
Solving our equation:
P = 500 / ( 1 + (0.07 × 15)) = 243.90243902439
P = $243.90
The principal investment required to get a total amount, principal plus interest, of $500.00 from simple interest at a rate of 7% per year for 15 years is $243.90. explantion to 11:First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year.
Solving our equation:
A = 500(1 + (0.07 × 15)) = 1025
A = $1,025.00
The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 7% per year for 15 years is $1,025.25.
A cone has a volume of 471cm. If the radius of the cone's base is 5cm what is the height of the
cone? (Round to the tenths place.)
(use 3.14)
Answer: the height is 18 cm.
Step-by-step explanation:
The equation for the volume of a cone is the following: V = 1/3 × B × h, where B (base) = πr². Because we are given the radius of the base, but not the base’s area itself, we will use V = 1/3πr²h.
Here, we are trying to solve for h, the height, so first we can first rearrange the equation to solve for h:
1) V = 1/3πr²h
2) h = V ÷ 1/3πr² (divide both sides by 1/3πr²h)
Now, we just need to input the given values: V = 471, π = 3.14, r = 5
h = 471 ÷ 1/3(3.14)(5²)
= 471 ÷ 1/3(3.14)(25)
= 471 ÷ 1/3(78.5)
= 471 ÷ (78.5/3)
= 18 cm

Answer: [tex]3x(2x^{3} + 5x + 8)[/tex]
Step-by-step explanation:
[tex]6x^{4} + 15x^{2} + 24x[/tex]
↓
[tex]3x(2x^{3} + 5x + 8)[/tex]
The factored expression is 3x(2x³ + 5x + 8).
To factor the expression 6x⁴ + 15x² + 24x using the greatest common factor (GCF), we first need to identify the common terms or factors that can be factored out from each term.
Step 1: Find the GCF of the coefficients (numbers).
The GCF of 6, 15, and 24 is 3.
Step 2: Find the GCF of the variables (x terms).
The GCF of x⁴, x², and x is x.
Step 3: Combine the GCF of the coefficients and variables.
The GCF of the entire expression is 3x.
Now, factor out 3x from each term:
3x * (2x³ + 5x + 8)
The factored expression is 3x(2x³ + 5x + 8).
