Find f(m - 1) when f(×) = 5×^2+4× - 5​

Mathematics

Nina [5.8K]3 years ago

Answer:

5m² - 6m + 1

Step-by-step explanation:

f(x) = 5x² + 4x - 5

substituting value,

f(m-1) = 5(m-1)² + 4(m-1) - 5

so,

5(m-1)² + 4(m-1) - 5

= 5(m²-2m+1) + 4m -1 - 5

= 5m² - 10m + 5 + 4m - 4

= 5m² - 6m + 1

The data given on the table about the ten participants in the health study shows that B. The post-run mean and median are the same value.

<h3>What is the post run mean?</h3>

This can be found as:

= (87 + 95 + 96 + 101 + 110 + 104 + 100 + 101 + 90 + 96) / 10

= 98

<h3>What is the post run median?</h3>

First order the pulses from smallest to largest:

= 87, 90, 95, 96, 96, 100, 101, 101, 104, 110

The two digits in the middle are:

96 and 100

The median will be:

= (96 + 100) / 10

= 98

In conclusion, option B is correct.

Determine whether the two ratios are proportional. <br><br> 6/36 and 1/6 <br><br> a) Yes <br> b) No
Xelga [282]
Yes, they are. Treat ratios like fractions, simplify them the same way. In 6/36, the GCF (Greatest Common Factor) of the numerator and the denominator is six. So, we divide both sides by six. This gives us 1/6, which is still the same fraction. (Making it proportional)
