Answer:

The triangle DEF

Step-by-step explanation:

If we see triangle ABC then by observing then we can say BC is base, AC is perpendicular and AB is hypotenuse .

When we rotate triangle ABC counter-clock wise rotation about P then

Then base BC becomes perpendicular of triangle, AC becomes base of triangle and  hypotenuse AB remains same .

We can see this process through diagram.

Hence, the final triangle we obtain after 90° rotation is look similar as triangle DEF

Between the time Iko woke up and lunchtime, tue temperature rose by 11 degrees. Then by the time he went to bed, the temperature
Ierofanga [76]

Answer:

T_b=(x-3)\textdegree

Step-by-step explanation:

let x° be temperature when he woke up. Given that the temperature rose  by 11° then later dropped by 14°. Also let T_b be temperature at time she went to bed.

-We add the temperature rise and subtract the temperature drop to find temperature at time she goes to bed.

-The temperature relative to time of waking up can be expressed as:

T_b=x\textdegree\pm\bigtriangleup T\textdegree\\\\T_b=x\textdegree+11\textdegree-14\textdegree\\\\T_b=(x-3)\textdegree

Hence, the temperature relative to the time Iko woke up is (x-3)°

1. Find a if x³ + ax² - x -8 is divisible by x -1​
Amanda [17]

Answer:

a = 8

Step-by-step explanation:

x-1 = 0

x = 1

let x³ + ax² -x -8 be p(x)

hence, p(1) = (1)³ + a(1)² -1 -8 = 0    (since, x-1 is a factor)

= 1 + a - 1-8

= a - 8 = 0

therefore, a = 8
