ps below. Equation: 3.57 x + 1.61 = 4.71 minus 2.63 x Step 1: 3.57 (0.5) + 1.61 = 4.71 minus 2.63 (0.5) Step 2: 1.785 + 1.61 = 4.71 minus 1.315 Step 3: 3.395 = 6.025 Which statement most accurately describes Tre’s error? Tre made an error when determining the original solution of x = 0.5. Tre made an error when substituting the solution in for x. Tre made an error when multiplying each coefficient by 0.5.

Answer:Tre made an error when adding or subtracting.

Step-by-step explanation:

the solution to the equation 3.57x + 1.61 = 4.71 minus 2.63 x is x = 0.5.

He verifies his solution using the steps below. Equation:

3.57 x + 1.61 = 4.71 minus 2.63x

Step 1: 3.57 (0.5) + 1.61 = 4.71 minus 2.63 (0.5)

Step 2: 1.785 + 1.61 = 4.71 minus 1.315

Step 3: 3.395 = 6.025

Looking at step 2, 4.71 minus 1.315 = 3.395. This would make the left hand side of the equation and the right hand side of the equation to be the same. Therefore,

Tre made an error when adding or subtracting.

The function f(x)= 1 divided by x is an example of an exponential function.<br> true<br> false
tensa zangetsu [6.8K]

This is a false statement.

Exponential functions are when there is a variable in the exponent. With x being in the denominator, this is the same as the function x^-1. Since the exponent is a number and not a variable, it is not a exponential function.

The volume of a cylinder is 480pie cm3. The height of the cylinder is 30 cm. What is the radius of the
guajiro [1.7K]

Answer:

R = 4cm

Step-by-step explanation:

V = π(R)²h = 480π

Divide by π

(R)²h = 480

Substitute h with 30

30*(R)² = 480

Divide by 30

(R)² = 16

Square root

R = 4cm

We do not accept R= -4 because it's a length, so it must be positive.

The height h of a projectile is a function of the time t it is in the air. the height in feet for t seconds is given by the func
alexgriva [62]

Domain means the values of independent variable(input) which will give defined output to the function.

Given:

The height h of a projectile is a function of the time t it is in the air. The height in feet for t seconds is given by the function

h(t)=-16t^2 + 96t

Solution:

To get defined output, the height h(t) need to be greater than or equal to zero. We need to set up an inequality and solve it to find the domain values.

To \; find \; domain:\\\\h(t) \geq0\\\\-16t^2+96t \geq  0\\Factoring \; -16t \; in \; the \; left \; side \; of \; the \; inequality\\\\-16t(t-6) \geq  0\\Step \; 1: Find \; Boundary \; Points \; by \; setting \; up \; above \; inequality \; to \; zero.\\\\t(t-6)=0\\Use \; zero \; factor \; property \; to \; solve\\\\t=0 \; (or) \; t = 6\\\\Step \; 2: \; List \; the \; possible  \; solution \; interval \; using \; boundary \; points\\(- \infty,0], \; [0, 6], \& [6, \infty)

Step \; 3:Pick \; test \; point \; from \; each \; interval \; to \; check \; whether \\\; makes \; the \; inequality \; TRUE \; or \; FALSE\\\\When \; t = -1\\-16(-1)(-1-6) \geq  0\\-112 \geq  0 \; FALSE\\(-\infty, 0] \; is \; not \; solution\\Also \; Logically \; time \; t \; cannot \; be \; negative\\\\When \; t = 1\\-16(1)(1-6) \geq  0\\80 \geq  0 \; TRUE\\ \; [0, 6] \; is \; a \; solution\\\\When \; t = 7\\-16(7)(7-6) \geq  0\\-112 \geq  0 \; FALSE\\ \; [6, -\infty) \; is \; not \; solution

Conclusion:

The domain of the function is the time in between 0 to 6 seconds

0 \leq  t \leq  6

The height will be positive in the above interval.
