Sam's height= 1.58m

Tom's height= 0.4m less than Sam's

= (1.58- 0.4)m

= 1.54m

F(x)=ax+b/2 then f^-1 (x-1) =2x-5/2 find a and b

krok68 [10]

From the given inverse function, we have

$f^{-1}(x-1) = 2x - \dfrac52 \\\\ \implies f^{-1}(x) = f^{-1}((x+1)-1) = 2(x+1) - \dfrac52 = 2x-\dfrac12$

By definition of inverse function,

$f\left(f^{-1}(x)\right) = x$

so that

$f\left(2x-\dfrac12\right) = x$

$a\left(2x-\dfrac12\right) + \dfrac b2 = x$

$2ax - \dfrac a2 + \dfrac b2 = x$

$\implies\begin{cases}2a=1 \\\\ -\dfrac a2+\dfrac b2 = 0\end{cases}$

$\implies \boxed{a=\dfrac12}$

$\implies \dfrac b2 = \dfrac a2 \implies \boxed{b=\dfrac12}$

How are surveys created to collect and analyze data?

NemiM [27]

Surveys are designed to find some results from different people across a state. For example a survey can be done on what type of medicine people take for diabetes. Now certain information that would be necessary for this survey can be included as questions and to analyze the data each and every option is compared with other choices. This can be compared using pie charts or histograms

Name two congruent angles that measure 15

snow_tiger [21]

Congruent angles have the same angle measures.
So: x + x = 15
2 x = 15
x = 15 : 2
x = 7.5°
Answer:
Those congruent angles measure 7.5° or 7° 30``.
