Shaun's savings can be modeled by the regression equation y = 6x^2 + 75x+200. Which of the following is the best prediction for

kipiarov [429]

Answer:

Option D

Step-by-step explanation:

The equation to predict the amount saved is

$y = 6x ^ 2 + 75x + 200.$

Assuming that the variable x represents the saving months, then substitute $x = 25$ in the quadratic equation and solve for y.

$y = 6 (25) ^ 2 +75 (25) +200\\\\y = \$\ 5,825$

The answer is the option D $5,825

m∠R = 27.03°

Solution:

Given In ΔQRP, p = 28 km, q = 17 km, r = 15 km

To find the measure of angle R:

Law of cosine formula for ΔQRP:

$r^{2}=p^{2}+q^{2}-2 pq \cos R$

Substitute the given values in the above formula.

$(15)^{2}=(28)^{2}+(17)^{2}-2 (28)(17) \cos R$

$225=784+289-952 \cos R$

$225=1073-952 \cos R$

Switch the given equation.

$1073-952 \cos R=225$

Subtract 1073 from both side of the equation.

$-952 \cos R=-848$

Divide by –952 on both sides.

$$ \cos R=\frac{106}{119}$

$$ R=\cos^{-1} \left(\frac{106}{119}\right)$

$R=27.03^\circ$

Hence m∠R = 27.03°.

How can you undo the addition of 7 on the left side of this equation? 6x + 7 = 19

BaLLatris [955]

6x - 7 = 19
6x = 19 + 7 
6x = 26 (divide both sides by 6 to get x) 
6x/6 = 26/6 
x = 4.33333333333
