andrew11 [14]2 years ago
6 0

Step-by-step explanation:

=  \frac{10ab}{ {c}^{3}d }  \div  \frac{15a {b}^{3} }{7 {c}^{3}  {d}^{4} }

=  \frac{10ab}{ {c}^{3} d}  \times  \frac{7 {c}^{3} {d}^{4}  }{15a {b}^{3} }

=  \frac{70ab {c}^{3} {d}^{4}  }{15a {b}^{3}  {c}^{3} d}

=  \frac{70}{15}  {a}^{1 - 1}  {b}^{1 - 3}  {c}^{3 - 3}  {d}^{4 - 1}

=  \frac{14}{3}  {a}^{0}  {b}^{ - 2}  {c}^{0}  {d}^{3}

=  \frac{14 {d}^{3} }{3 {b}^{2} }

Find the equation of the line passing through point (4,2) and perpendicular to AB
Setler [38]

Answer:

a. -⅓

b. 3

c. y = 3x - 10

Step-by-step explanation:

a. Gradient of line AB:

A(1, 3), B(7, 1)

Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 3}{7 - 1} = \frac{-2}{6} = -\frac{1}{3}

Gradient (m) = -⅓

b. The of the line that is perpendicular to line AB would be the negative reciprocal of the gradient of line AB.

Thus, the negative reciprocal of -⅓ = 3

Gradient of the line perpendicular to line AB = 3

c. Equation of the line that passes through (4, 2) and is perpendicular to line AB:

We can write the equation using the point-slope form equation, y - b = m(x - a), where,

(a, b) represents a point on the line, and,

m = gradient/slope

We know that the gradient/slope (m) = 3

Also, a point, (a, b) = (4, 2).

Therefore, substitute a = 4, b = 2, and m = 3 into y - b = m(x - a)

Thus:

y - 2 = 3(x - 4)

y - 2 = 3x - 12

Add 2 to both sides

y = 3x - 12 + 2

y = 3x - 10

A middle school held a Career Exploration Day where students could choose to hear an adult talk about his or her career. 15 stud
mash [69]

Answer:

5/12

Step-by-step explanation:

15 students went to hear the doctor speak and 21 students went to other sessions

How many students are there? 15 + 21 = 36 students

Therefore, the probability to randomly select a student that went to hear the doctor is \frac{15}{36}, then simplifying it by 3 is \frac{5}{12}.

If we want to express it in percentage it would be 41.6%
