1520 ÷ 10 = 152
1520 ÷ 20 = 76
1520 ÷ 40 = 38
X. Y
12 —> 4
8 —> 8/3
13 —> 13/3
Substitute x values for y.
y = 1/3(12)
y=4
Answer:
9 hr * 60 min/hr = 540 min. 540 min * 60 sec/min = 32,400 sec. Use the method described by panic mode: round the number down until there is only one non-zero digit left. Here, 32,400 rounds down to 30,000. Now count the number of zeroes; the result is the order of magnitude: 4. (You see this in scientific notation also: 30,000 = 3 × 10^4.)
Answer:
Domain (-3, 4, 5)
Range (1, 2, 6)
Step-by-step explanation:
Domain is your x so all of the values that can go into a relation or function (which is your input) are called Domain. Domain is also all of the set of elements of ordered pair ( which is the x coordinates).
Range is your y so all the values that can go into a relation or function ( which is your output) are called Range. Range is also all the set of second elements of ordered pair ( which is the y coordinates).
So, basically you just look at all the number that come first so say you have
(1,2), (2,3), (3,4)
Your first numbers to each point are (1, 2, 3) which is your Domain
then look at the second number which are (2, 3, 4) which is your Range.
Hope this helps!
Answer:
7.5 cm^2
Step-by-step explanation:
Aqui, temos Cos A = 0,8 = 8/10 = 4/5.
Cos B = 0,6 = 6/10 = 3/5.
O que isto significa é que os dois outros lados do triângulo retângulo são 3 cm e 5 cm, respectivamente.
Isso ocorre porque, o oposto do ângulo agudo A é adjacente ao ângulo agudo B e vice-versa.
Portanto, a partir dos valores de ambos, podemos obter os dois outros lados.
Matematicamente, a área da direita é 1/2 * b * h b e h são 3 e 5, respectivamente.
Assim, área = 1/2 * 3 * 5 = 7,5 cm ^ 2
