Answer:
<h2>The range: {0, 10, 42}</h2>
Step-by-step explanation:
Put the values of x from the domain to the equation of the function
f(x) = 2x² - 8
for x = -2
f(-2) = 2(-2)² - 8 = 2(4) - 8 = 8 - 8 = 0
for x = 3
f(3) = 2(3)² - 8 = 2(9) - 8 = 18 - 8 = 10
for x = 5
f(5) = 2(5)² - 8 = 2(25) - 8 = 50 - 8 = 42
Answer:
30
Step-by-step explanation:
you just multiply both the 7 and the 3 by ten
The boss is correct because if you press the button 5 time knowing that if u press it one time it is going to have the photo at 7.04 inches so if you keep going by the time you get to 5 times it is going to about 4.22 so you would have had to press it 4 times which would equal 5.4 inches
Answer:
There is not a geometric or arithmetic sequence.
Step-by-step explanation:
Answer:

see in the picture, E is the centre of the kite
1) AC = 2.EC = 40
2) CD = sqrt( ED² + EC² ) = sqrt(21² + 20²) = 29
3) ABE = 90⁰ - 51⁰ = 39⁰
4) BCE = BAE = 51⁰
<u>p</u><u>a</u><u>r</u><u>t</u><u> </u><u>2</u><u>:</u>
we have:
3x + 7 = (3x - 1 + 8x)/ 2
<=> 3x + 7 = 5.5x - 0.5
<=> 2.5x = 7.5
<=> x = 3
5) with x = 3 => UV = 3.3 - 1 = 9 - 1 = 8
6) XY = 3.3 + 7 = 9 + 7 = 16
7) TW = 8.3 = 24

we have:
28.5 = (x + 25)/2
<=> x + 25 = 57
<=> x = 32
