Answer:

Choice B

Step-by-step explanation:

The range of a function refers to the set of y-values (dependent variable) for which a particular function is real and defined. From the graph given, the least possible value of y is -5 while the maximum value of y is 5. This implies that the range of the function is between -5 and 5 inclusive

love history [14]

Answer:

(i) 22.5

(ii) 7.2

Step-by-step explanation:

(i)

AB:PQ = 2:5 = 1:2.5

So PQ is 2.5 times longer than AB.

PQ=2.5AB=(2.5)9=22.5

(ii):

Since the triangles are similar, their sides are in ratio to each other. So if PQ was 2.5 times longer than AB, QR must also be 2.5 times longer than BC:

QR=2.5BC

BC=QR/2.5=18/2.5=7.2

Use log 2=a, log 3=b to evaluate log 216

Anuta_ua [19.1K]

Answer:

answer = 3(a +b)

Step-by-step explanation:

$log(2) = a \: log(3) = b \: \: \\ log(216) = log(2 \times 2 \times 2 \times 3 \times 3 \times 3) \\ = log( {2}^{3} \times {3}^{3} ) \\ = log(2^{3} ) + log( {3}^{3} ) \\ = 3 log(2) + 3 log(3) \\ = 3(a) + 3(b) \\ = 3(a + b) \\ \\ log(216) = 3(a + b)$

Help quick please, look at the photo I attached

Tema [17]

Answer:

A ≈ 5.6

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = $\frac{1}{2}$ × PQ × PR × sin P

= 0.5 × 5.2 × 2.8 × sin50°

≈ 5.6 ( to 1 dec. place )
