The ratio of the measures of the three angles is 2:6:7. Find the measure of each angle of the triangle.

1 answer:

5 0

Answer: C, because I’m assuming you meant 84°.
Explanation: 2+6+7 is equal to 15. The three angles of a triangle will always add up to 180, so you need to divide 180 by 15, which is 12. Then, multiply each number (2, 6, and 7) by 12 to get your answer, which is 24, 72, and 84 :)

Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly. Find the errors in her solution. What should her answer have been?

Irina-Kira [14]

Answer: The correr solution is $x=\frac{17}{34}$

Step-by-step explanation:

Since the steps in Lin's solution are not shown, we are not able to find her erros. However, we can solve it step by step and find the correct result:

$8(x-3)+7=2x(4-17)$

Firstly, in the left part of the equation we have to multiply $8$ by the numbers inside the parenthesis; and in the right side we have to solve first what is inside the parenthesis:

$8x-24+7=2x(-13)$

Adding similar terms in the left side and multiplying $2x$ by the number inside the parenthesis in the right side:

$8x-17=-26 x$

Isolating $x$ :

$x=\frac{17}{34}$ This is the correct solution

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

NISA [10]

The exponential function y = 290 · 0.31ˣ reports a decay as its growth rate is less than 1 and greater than 0. Its percentage rate of decrease is equal to 69 %.

<h3>How to determine the behavior of an exponential function</h3>

Exponential functions are trascendental functions, these are, functions that cannot be described algebraically. The simplest form of exponential functions is shown below:

y = a · bˣ (1)

Where:

a - Initial value
b - Growth rate
x - Independent variable.
y - Dependent variable.

Please notice that this kind of exponential function reports a growth for b > 1 and decay for b < 1 and b > 0. According to the statement we have the function y = 290 · 0.31ˣ, then we conclude that the exponential function given reports a decay.

The percentage rate of decrease is determined by the following formula:

100 × (1-0.31) = 100 × 0.69 = 69 %

The percentage rate of decrease related to the exponential function is 69 %.
