Ok, so for this question you need to remember PEMDAS (Parenthesis, Exponents, Multiply, Divide, Add, Subtract) So then
-2 * (-10.5 / (2 + 3))
= -2 * (-10.5 / (5))
= -2 * ( -2.1)
= 4.2
There you go.

Solve using the substitution method.

Brilliant_brown [7]

Answer:

x = 1, y = 4

Step-by-step explanation:

This is very simple

Since you have 2 equations with the same coefficient of x, just minus one equation from another:

x + 3y = 13

x + 2y = 9

1y = 4

Sub y = 4 into any of the 2 equation,

x + 3(4) = 13

x + 12 = 13

x = 13 - 12

= 1

You are given the parametric equations x=2cos(θ),y=sin(2θ). (a) List all of the points (x,y) where the tangent line is horizonta

vladimir1956 [14]

Answer:

The solutions listed from the smallest to the greatest are:

x: $-\sqrt{2}$ $-\sqrt{2}$ $\sqrt{2}$ $\sqrt{2}$

y: -1 1 -1 1

Step-by-step explanation:

The slope of the tangent line at a point of the curve is:

$m = \frac{\frac{dy}{dt} }{\frac{dx}{dt} }$

$m = -\frac{\cos 2\theta}{\sin \theta}$

The tangent line is horizontal when $m = 0$ . Then:

$\cos 2\theta = 0$

$2\theta = \cos^{-1}0$

$\theta = \frac{1}{2}\cdot \cos^{-1} 0$

$\theta = \frac{1}{2}\cdot \left(\frac{\pi}{2}+i\cdot \pi \right)$ , for all $i \in \mathbb{N}_{O}$

$\theta = \frac{\pi}{4} + i\cdot \frac{\pi}{2}$ , for all $i \in \mathbb{N}_{O}$

The first four solutions are:

x: $\sqrt{2}$ $-\sqrt{2}$ $-\sqrt{2}$ $\sqrt{2}$

y: 1 -1 1 -1

The solutions listed from the smallest to the greatest are:

x: $-\sqrt{2}$ $-\sqrt{2}$ $\sqrt{2}$ $\sqrt{2}$

y: -1 1 -1 1

Which of the following pairs is not correctly written in scientific notation?

Mnenie [13.5K]

The answer is:
__________________________________________________
[B]: "6,500 = 6.5 ² ".
__________________________________________________________
Note: This is the correct answer choice because this chioce is INCORRECT;

Note: "6,500 = 6.5 * 1000 = 6.6 * 10³ " ; note that: "6.5 * 10² = 6.5 * 100 = 650.

Take note of this very answer chioce: "650 = 65 * 100 = 6.5² * 10² . " ;
