Answer:
C
Step-by-step explanation:
Since CB is a tangent to the circle then ∠ ABC = 90°
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, thus
AC² = 5² + 8² = 25 + 64 = 89 ( take the square root of both sides )
AC =
→ C
Answer:
The answer is 48
Step-by-step explanation:
It is a product. So it is (B)
Hope I helped :)
Let's do the sum first:
x+4-8x+10 = x-8x +4+10 = -7x + 14
coefficient is the number beside the x.
so the coefficient for this sum is -7
The equation for the line of best fit is the <em>linear</em> function y = - 0.4 · x + 70. (Correct choice: A).
<h3>What linear equation best fits the scatter plot?</h3>
The equation of the line is represented by a polynomial of the form y = m · x + b, where m is the slope of the line and b is the intercept of the line. The slope is equal to the change in the <em>dependent</em> variable (Δy) and in the <em>independent</em> variable (Δx) and the intercept is the <em>vertical</em> distance of the line with the origin when x = 0.
In accordance with the picture, we notice that the scatter plot indice that Δy < 0 and Δx > 0 and therefore, m < 0. Besides, the intercept of the equation of the line must be greater than zero. Thus, the equation for the line of best fit is the <em>linear</em> function y = - 0.4 · x + 70. (Correct choice: A)
