Answer:

subtract 3 from both sides to get 3+z=-19 3+z-3=-19-3 z = -22 So it's only true when z = -22. This means that it's neither 100% true nor 100% false. So it's an open statement or sentence

Answer:

First thing you would do is subtract 3 from both sides to get 3+z=-19 3+z-3=-19-3 z = -22 So it's only true when z = -22. This means that it's neither 100% true nor 100% false. So it's an open statement or sentence

For any two nonzero integers the product and quotient have the same sign.

This statement is always true. For any two nonzero integers the product and quotient have the same sign. For example, -2*-3 = 6 and of we see -2/-3, then the result is 2/3. The sign in the result is same after product and quotient, but the result has the same sign.

Let f(t)=F′(t), with F(t)=7t2+3t, and let a=2 and b=4. Write the integral ∫ baf(t).dt and evaluate it using the Fundamental Theorem of Calculus.

Applying the Fundamental Theorem of Calculus, the result of the integral is: 90.

The Fundamental Theorem of Calculus states that:

For this problem, we have that:

Then, applying the Theorem:

The result of the integral is of 90.

A similar problem is given at brainly.com/question/13755352

Answer:

the integral I = 90

Step-by-step explanation:

for

F(t)=7t²+3t and f(t)=F′(t)

then for a=2 and b=4 and according the Fundamental Theorem of Calculus

then

F(b) = F(t=4) = 7*4²+3*4 = 124

F(a) = F(t=2) = 7*2²+3*2 = 34

thus

I = F(b)-F(a)= 124 - 34 = 90

I = 90
