Answer: The temperature dropped 8 degrees.

Step-by-step explanation:

The initial temperature was T0, and each hour the temperature dropped by 2°, for 4 hours.

So we can write the temperature as a function of time in the next way:

T(t) = T0 - (2°/h)*t

where t is the number of hours since the temperature started to drop.

The temperature drop for four hours, so we have that the final temperature is:

T(4h) = T0 - (2*4)°= T0 - 8°

then we can calculate the difference between the final and initial temperature as:

T(4h) - T(0h) = T0 - 8° - T0 = -8°

This means that in Friday morning the temperature dropped by 8 degrees.

Q2 (i). A line “t” is parallel to 3y = 6x + 9. Find the slope of this line “t”. (ii) Another line “r” is perpendicular to the li
Mariulka [41]

Answer: 6 and -1/6

Step-by-step explanation:

solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.

Question 1 of 10
Archy [21]

Answer:

A. y = 7(x + 1)²-3

Step-by-step explanation:

Parabola:

y = 7x^{2} + 14x + 4

y = 7(x^{2} + 2x) + 4

Putting into vertex form, remember that:

(x + a)^{2} = x^{2} + 2ax + a^{2}

In this question:

x^{2} + 2x, to put into this format:

x^{2} + 2x + 1 = (x + 1)^{2}

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then

Vertex form:

y = 7(x^{2} + 2x + 1) + 4 - 7

y = 7(x + 1)^{2} - 3

So the correct answer is:

A. y = 7(x + 1)²-3
