2. Write the formula for finding the rate.
How we found a special maths equation hidden in rat whiskers
Robyn Grant, Manchester Metropolitan University
January 27, 2020 2.27pm GMT
Rats have up to 70 whiskers on their faces, varying hugely in size and shape. Almost every mammal possesses whiskers, but these rodents are what we call “whisker specialists”, meaning they have super-sensitive, moveable hairs that they use to explore and sense their surroundings.
Rat whiskers can vary hugely. In our recent research, my colleagues and I analysed 523 whiskers from 15 rats and found that each whisker had a different length and shape. We wanted to investigate more about the shape of these hairs as a first step in understanding what rats feel through their whiskers

5. A function is defined by the formula f(x) = ax + b. if f (4) = 5 and f (-2) = 7 Find : a. the value of a and b b. the function formula tolongin yaa :D
Diketahui sebuah Fungsi dengan :
f(x) = ax + b
f(4) = 4a + b = 5......(1)
f(-2)= -2a + b =7......(2)
Ditanay = a?, b?, Fungsi Persamaan?
Carilah Hasil A dan B dari (1) dan (2) dengan cara menguranginya
4a-(-2a) +b - b = 5-7
6a= -2
a= (-1/3)
b= 4× (-1/3) +b =5
-4/3-5= -b
b = 4/3 + 5 = 19/3
.
Fungsi
F(x) = -1/3 x + 19/3
6. 9 Given the functions f(x)= x² - x and g(x)= x² – 3x – 12,asolve the equation f(x) = 6b solve the equation f(x) = g(x).
Penjelasan dengan langkah-langkah:
a.) f(x)=6
=>6=x²-x
x² - x - 6 = 0
(x + 2) (x - 3) = 0
x = -2, and x = 3
b.) f(x) = g(x)
g(x) = 6
=>6=x²-3x-12
=> x² - 3x - 12 - 6
=> x² -3x - 18
(x - 6) (x + 3) = 0
=> x=6,andx=-3
7. Solve for x and find the measure of the bold angle
[tex]16x - 6 = 14x + 6 \\ 16x - 14x = 6 + 6 \\ 2x = 12 \\ x = \frac{12}{2} \\ x = 6 \\ \\ bold \: angle \\ 14x + 6 \\ 14.6 + 6 \\ 84 + 6 \\ 90[/tex]

11. A function f is defined by f:x --> 5-2 sin 2x for 0 <= x <= π . Solve the equation f(x) = 6 , giving answers in terms of π
f(x) = 5 - 2 sin 2x ; 0 ≤ x ≤ π
f(x) = 6
5 - 2 sin 2x = 6
-2 sin 2x = 1
sin 2x = -½
Notice that the interval is 0 ≤ x ≤ π, which is in quadrant I and quadrant II. Because the value of sin x is negative, then x is in quadrant III and quadrant IV. Therefore, none of the x values are satisfactory. Or it can be said that the solutions for the above equation does not exist.

Answer:
3t²– 4t = 7
3t²– 4t -7 = 0
a = 3
b = -4
c = -7
[tex]t_{1,2}[/tex] = [tex]\frac{-b +- \sqrt{b^2-4ac} }{2a}[/tex]
= [tex]\frac{-(-4) +- \sqrt{(-4)^2-4(3)(-7)} }{2(3)} \\[/tex]
= [tex]\frac{4 +- \sqrt{16-(-84)} }{6} \\[/tex]
= [tex]\frac{4 +- \sqrt{16+84} }{6} \\[/tex]
= [tex]\frac{4 +- \sqrt{100} }{6} \\[/tex]
= [tex]\frac{4 +- 10 }{6} \\[/tex]
= [tex]\frac{2 +- 5 }{3} \\[/tex]
t₁ = [tex]\frac{2 + 5 }{3}[/tex]
t₁ = [tex]\frac{7}{3}[/tex]
