Answer:

(C) 1/2

Step-by-step explanation:

  • s + 3s = 4s
  • t + 3t = 4t

If 4s is 2 more than 4t, then:

  • 4s = 2+ 4t
  • 4s - 4t = 2
  • 4s/4 - 4t/4 = 2/4
  • s - t = 1/2

(C) is the answer

1/2 (a+b)h

1/2 (a+16)14=132

8×14=112

14÷2=7

132-112=20

20÷7 =2.857142857

so then a= 2.86 (3sf)

Find the derivative of the function using the definition of derivative. g(t) = 7 t g'(t) = State the domain of the function. (En
Vedmedyk [2.9K]

Answer:

R = \{ \forall x \in \mathbf{R}|-\infty <  x < \infty\}

Step-by-step explanation:

The definition of derivative states that:

g'(t) =  \lim_{h \to 0} \frac{g(t+h)-g(t)}{h}

Then:

g'(t) =  \lim_{n \to \infty} \frac{7\cdot (t+h)-7\cdot t}{h}

g'(t) =  \lim_{h \to 0} 7

g'(t) = 7

A constant function is a zero-order polynomial. The domain of any real polynomial is \mathbf{R}. Then, the domain of the function is:

R = \{ \forall x \in \mathbf{R}|-\infty <  x < \infty\}
