TTese are all parabolas whose axis of symmetry is the y axis. The negative coefficient means they open downwards and the positive mean they open upwards. The higher the absolute value of the coefficient is the greater the slope, so 2x^2 will be steeper than x^2 and -4x^2 will be steeper than - 2x^2.
So h(x) and j(x) are the answers.
Answer:
25, right, 5, 3, 4,
Step-by-step explanation:
5^2 = 5*5 = 25
the triangle has a right angle and is therefore a right triangle,
the sides of the squares that make up the triangle are length 5, length 3, and length 4

Divide the fractions in the calculator, until you get a repeating number
Answer:
The 31st term is 84
Step-by-step explanation:
Here, we want to calculate the 31st term of the sequence
Firstly, we need to determine the type of sequence herein
As we can see;
200-204 = 196-200 = -4
The relationship between the numbers is a sum, that means the sequence is arithmetic
and; -4 represents the common difference
Mathematically, the nth term of an arithmetic sequence can be calculated using the equation;
Tn = a+ (n-1)d
with respect to the question;
a is the first term = 204
n = 31 and d = -4
Substituting these numbers;
T31= 204 + (31-1)-4
T31 = 204 - 4(30)
T31 = 204 - 120
T31 = 84
Answer:
3 cm on the map represents 31.5 km in reality.
3cm : 31.5 km
1cm : 31.5/3 km
1cm : 10.5km
So the scale on the map is 1cm represents 10.5 km.
