To pass this year's math class, Miriam needs to earn at least an 82%. Write an inequality that shows the scores Miriam could get

sergey [27]

The inequality that shows the scores Miriam could get to pass her math class is $82\%\leq x \leq 100\%$

Solution:

Given that To pass this year's math class, Miriam needs to earn at least an 82%

To find: Inequality that shows the scores Miriam could get to pass her math class

Let "x" be the Miriam's score in the math class

Given she should score at least 82 %

Therefore, we can frame a inequality as:

$x\geq 82 \%$

Here we used "greater than or equal to" , because she can score 82 % or more than 82 % also

The maximum score is 100 %

Hence we can frame a inequality as:

$x\leq 100 \%$

Here, we used "less than or equal to" , because she can score the maximum score of 100 % or less than 100 %

Combining both the inequalities we get,

$82\%\leq x \leq 100\%$

All real numbers greater than or equal to 82% and less than or equal to 100%

Thus the required inequality is found

we know that

1) scale factor is equal to $\frac{1}{10}$

2) The ratio of the perimeters of the triangles is equal to the ratio of the measures of the sides

3) the longest side of ∆ABC=[scale factor]*the longest side of ∆DEF

the longest side of ∆ABC= $\frac{1}{10}*40$

the longest side of ∆ABC= $4$ units

the answer part a) is

the longest side of ∆ABC is $4$ units

Part b)

The ratio of the area of ∆ABC to the area of ∆DEF is equal to the scale factor squared

$[scale factor]^{2} =(\frac{1}{10})^{2} \\ \\ =\frac{1}{100} \\ \\ =0.01$

therefore

the answer part b) is

The ratio of the area of ∆ABC to the area of ∆DEF is $\frac{1}{100}$

Which statement describes the end behavior of the exponential function f(x) = 2x – 3?

charle [14.2K]

The correct answer is:

As x→-∞, y→-3.
As x→∞, y→∞.

Explanation:

As our values of x get further into the negative numbers, the value of 2ˣ will approach 0. This is because raising a number to a negative exponent "flips" the number below the denominator and raises it to a power; we end up with smaller and smaller fractions, eventually so small that they nearly equal 0.

This will make the value of the function 0-3=-3.

As x gets larger and larger (towards ∞), the value of y, 2ˣ, continues to grow as well. Since it continues to grow exponentially, we say the value approaches ∞.
