Let f(x)=x2−3x−4 . What is the average rate of change from x = 7 to x = 10? Question 6 options: 24 14 66 42
Fed [463]
Just find the slope between the points

basically find (f(10)-f(7))/(10-7)

f(7)=7^2-3(7)-4=49-21-4=24
f(10)=10^2-3(10)-4=100-30-4=66

slope=(66-24)/(10-7)=42/3=14
average rate of change is 14

X(15-x)=50 quadratic equations
meriva

Answer:

15x -  {x}^{2}  =50 \\  {x }^{2}  - 15x  + 50 = 0 \\  {x}^{2} - 10x - 5x + 50 = 0 \\ x(x - 10) - 2(x - 10) = 0 \\ (x - 2)(x - 10) = 0 \\ x = 2 \: and \: x = 10

A company plans to build at least 152 igloos in a single week by employing skilled workers from the cities of Tomsk and Kyzyl. A
xxTIMURxx [149]

Answer:

Each Tomskian build 6 igloos per week.

Each Kyzylian build 5 igloos per week.

Step-by-step explanation:

Let T represent the number of Tomskians and K represent the number of Kyzylians the company needs to employ to meet its goal.

The inequality: 6T+5K\geq152 represents the situation that a company plans to build at least 152 igloos in a single week by employing T Tomskians and K Kyzylians.

We can see that 6T represents the number of igloos made by T Tomskians in one week and 5K represents the number of igloos made by K Kyzylians in one week .

Since all Tomskians and Kyzylians build the same number of igloos per week, therefore, each Tomskian build 6 igloos per week and each Kyzylian build 5 igloos per week.
