Answer:
y = 4.375x + 2.5
Step-by-step explanation:
The equation of the line is expressed as y = mx+c
m is the slope
c is the intercept
Using the coordinate points (0, 2.5), (4, 20)
Slope m = 20-2.5/4-0
m = 17.5/4
m = 4.375
Get the intercept
Substitute (0, 2.5) and m = 4.375 into y - mx+c
2.5 = 4.375(0) + c
2.5 = c
Get the equation required
y = 4.375x + 2.5
Answer:
L = s^2/(30.25Cd)
Step-by-step explanation:
In accident investigation, the speed of a vehicle can be estimated using a polynomial function that relates speed (s) to the length of skid marks (L). The drag coefficient Cd will depend on the condition of the road surface and tires, but might be expected to be between 0.7 and 0.8.
If the skid marks end in a collision, the length of the marks that might have been made can be estimated using this formula, then that length added to the actual length of marks to estimate the original speed. The speed at the point of collision can be estimated by the damage caused, and/or the movement created.
In the above formula, length is in feet, and speed is in miles per hour.

5 raised garden beds will need 178×5=890 bags of soil
Answer:Simplificando
5 (2j + 3 + j) = 0
Reordene os termos:
5 (3 + 2j + j) = 0
Combine termos semelhantes: 2j + j = 3j
5 (3 + 3j) = 0
(3 * 5 + 3j * 5) = 0
(15 + 15j) = 0
Resolvendo
15 + 15j = 0
a verdadeira questão é por que o vizinho de Sarah quer dentes de tubarão
Step-by-step explanation:
Mova todos os termos contendo j para a esquerda, todos os outros termos para a direita.
Adicione '-15' a cada lado da equação.
15 + -15 + 15j = 0 + -15
Combine termos semelhantes: 15 + -15 = 0
0 + 15j = 0 + -15
15j = 0 + -15
Combine termos semelhantes: 0 + -15 = -15
15j = -15
Divida cada lado por '15'.
j = -1
Simplificando
j = -1
Tubarão ou cação é um tipo de peixe de esqueleto cartilaginoso e um corpo hidrodinâmico (com exceção dos Squatiniformes, Hexanchiformes e Orectolobiformes)
