2. 12335.85
3. 182.33
4. 8934.17
The length of TU = 156.15 m
The area of the triangle is 6167.93 m²
The length of GH = 182.33 m
The area of the triangle is 8934.3 m²
How to find area of a triangle?
area of a triangle = 1 / 2 bh
where
b = baseh = heightTherefore, the height of the triangle can be found using Pythagoras theorem.
Hence,
h² = 175² - 79²
h = √24384
h = 156.153770368
TU = 156.15 m
area = 1 / 2 × 156.15 × 79 = 6167.925 m²
GH² = 207² - 98²
GH = √33245
GH = 182.33211456
GH = 182.33 m
area = 1 / 2 × 182.33211456 × 98 = 8934.27361345 = 8934.3 m²

2. The electrical resistance R of a wire varies inversely with the square of its diameter d. If a wire with a
diameter of 3 millimeters has a resistance of 0.4 ohm, find the resistance of a wire having the same
length and a diameter of 8 millimeters.
Answer:
[tex]0.225 \Omega =225 m\Omega[/tex]
Step-by-step explanation:
We know (Ohm second law) that [tex]R= \frac{k}{d^2}[/tex] where k inlcudes the rest of the parameters (material, lenght). In our situation we have k= [tex]0.4\cdot9 \Omega mm^2[/tex]. The moment the diameter becomes 8mm R becomes
[tex]R= {{0.4\cdot 9}\over{16}} \Omega = 0.225 \Omega[/tex]

The variable f varies inversely as the square root of g. When f = 4, g = 4. Jordan’s work finding the value of f when g = 100 is shown: f = k 4(4) = k 16 = k f = 16 f = 16 10f = 16 f = 1.6 What is the first error, if any, in Jordan’s work?
Variation can be direct, inverse or jointly
Jordan's first error is that he incorrectly calculated the value of proportionality constant
From the question, we understand that f varies directly as the square root of g.
This variation is represented as:
[tex]\mathbf{ f\ \alpha\ \frac{1}{\sqrt{g}}}[/tex]
Express as a equation
[tex]\mathbf{ f\ \ =\ k\frac{1}{\sqrt{g}}}[/tex]
When f = 4, k = 4.
So, we have:
[tex]\mathbf{ 4\ \ =\ k\frac{1}{\sqrt{4}}}[/tex]
[tex]\mathbf{ 4\ \ =\ \frac{k}{2}}[/tex]
Multiply both sides by 2
[tex]\mathbf{ k = 8}[/tex]
When g = 100, we have:
[tex]\mathbf{ f\ \ =\ k\frac{1}{\sqrt{g}}}[/tex]
[tex]\mathbf{ f\ \ =\ 8 \times \frac{1}{\sqrt{100}}}[/tex]
[tex]\mathbf{ f\ \ =\ 8 \times \frac{1}{10}}[/tex]
[tex]\mathbf{ f\ \ = 0.8}[/tex]
This means that, Jordan incorrectly calculated the value of proportionality constant

it is a three digit whole number it is divisible by 2 it is divisible by 4 it is divisible by 5 it is divisible by 3 it is divisible by 6 it is divisible by 9 it is less than 300 it is greater than 150 it is a multiple of 90
Answer:
Is it perhaps one hundred and eighty (80)
Answer:
180
Step-by-step explanation:
180/2=90
90x2=180
180/4=45
180/5=36
180/6=30
180/9=20
the answer is 180 because it is less than 300, more than 150, and all of those numbers get whole numbers when they are divided. if you needed to know it is 2 sets of 90.
the x-intercept of the graph of f(x)=3log(x-5)+2 is:
Answer:
C
Step-by-step explanation:
To find the x- intercept let f(x) = 0 , then
3log(x - 5) + 2 = 0 ( subtract 2 from both sides )
3log(x - 5) = - 2 ( divide both sides by 3 )
log(x - 5) = - [tex]\frac{2}{3}[/tex] , then
x - 5 = [tex]10^{-\frac{2}{3} }[/tex] ( add 5 to both sides )
x = [tex]10^{-\frac{2}{3} }[/tex] + 5 → C
Divide.

solve using quadratic formula x^2-5x+4=0
Answer: x = 4,1
Step-by-step explanation:
Answer:
x = 4 or x = 1
Step-by-step explanation:
x² - 5x + 4 = 0
⇒ x² - 4x - x + 4 = 0
⇒ x (x - 4) - 1 (x - 4) = 0
⇒(x - 4)(x - 1) = 0
Therefore,
x - 4 = 0
⇒ x = 4
Again.
x - 1 = 0
⇒ x = 1
Hence, x = 4 or x = 1 :)

Solve the Quadratic equation
8n²-56=48n
Answer:
n = {-1, 7}
Step-by-step explanation:
8n² - 56 = 48n
Subtract 48n from both sides
8n² - 48n - 56 = 0
Divide both sides by 8
n² - 6n - 7 = 0
Factor
alternately use the quadratic equation or complete the square
(n - 7)(n + 1) = 0
n = {-1, 7}
Find the value of a/b when a=$13. 93 and B=0. 07
Thank you.
Answer:
10
Step-by-step explanation:
A = 7, B = 2
7 = 2 * 3 + 1
7 mod 2 = 1
A = 8, B = 4
8 = 4 * 2 + 0
8 mod 4 = 0
A = 13, B = 5
13 = 5 * 2 + 3
13 mod 5 = 3
A = -16, B = 26
-16 = 26 * -1 + 10
-16 mod 26 = 10
