Answer:
C) The third table. K= 5
Step-by-step explanation:
1) Below there are the missing data:
A proportional relationship through a constant k. It is obtained when we divide:
2)In this case, when we divide the temperature (T) by the time (h).
3)So, examining the table below we are searching for a ratio k common to all measures (temperatures over hour).
3/6 is less than 4/6.
think of pizza
there are 6 slices.
which is more, 3 out 6 slices or 4 out of 6.
hope that helped :)
Answer:
i think 8/25
Step-by-step explanation:
Answer:
x = - 5, x = 3
Step-by-step explanation:
To find the x- intercepts equate f(x) to zero, that is
x² + 2x - 15 = 0 ← in standard form
Consider the factors of the constant term ( - 15) which sum to give the coefficient of the x- term ( + 2)
The factors are + 5 and - 3, since
5 × - 3 = - 15 and 5 - 3 = + 2, hence
(x + 5)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5 ⇒ (- 5, 0 ) ← x- intercept
x - 3 = 0 ⇒ x = 3 ⇒ (3, 0 ) ← x- intercept
Drawing a picture definitely helps! since BD is 6", it is split evenly into 3 and 3. AC is the same except it splits into 4 and 4. because AC and BD are perpendicular to each other, the crossing lines form a 90 degree angle. in this case, the missing side is 5 because the sections form a pythagorean triple (3, 4, 5). you could do the pythagorean theorem (a^2 + b^2= c^2) but having some pythagorean triples memorized will help a lot. i hope this helped!
