Answer:
Step-by-step explanation:
You can see that (0,6) and (1,1) are points on the line.
Use their coordinates to calculate the slope.
slope = (6-1)/(0-1) = 5/(-1) = -5
You can also see that the y-intercept is 6.
Slope-intercept equation of the line: y = -5x+6
Answer:
P = 0.09r²
Step-by-step explanation:
Price, p is proportional to the square of its radius, r
P = k*r²
a mirror with radius 20cm has a price of £36
P = k * r²
36 = k * 20²
36 = k * 400
36 = 400k
k = 36/400
k = 0.09
Substitute the value of k into the equation:
P = k * r²
P = 0.09 * r²
P = 0.09r²
Answer:27x
Step-by-step explanation:
It is 27x because 12 + 15 = 27 then add the x
47 days because If it’s half of the lake and doubles one more time then it would be the full lake
A chemical bond<span> is a lasting attraction between </span>atoms<span> that enables the formation of </span>chemical compounds<span>. The bond may result from the </span>electrostatic force<span> of attraction between atoms with opposite charges, or through the sharing of electrons as in the </span>covalent bonds<span>. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or </span>ionic bonds<span> and "weak bonds" such as </span>Dipole-dipole interaction<span>, the </span>London dispersion force<span> and </span>hydrogen bonding<span>.</span>
