In your lab, a substance's temperature has been observed to follow the function T(x) = (x + 5)3 + 7. The turning point of the gr
OleMash [197]
So essentially, this is a cubic function where T(x) = y, and:
y =  {(x+5)}^{3} +7
In order to find the vertices, aka "turning points", we need to see around what area the graph will curve quickly from bottom-left to top-right. If the value being cubed (in the parentheses) is around -8, y will be close to 0, since -8+7=-1. (-2)^3 = -8. So x+5=-2, x=-7.
At x=-6, y = (-6+5)^3+7 = (-1)^3+7
y = -1+7 = 6
At x=-5, y = 0+7 = 7
Above x=-4, the y jumps rapidly above 10, and below x=-9, the y jumps rapidly below -50
What does all that mean???
That between x = -9 and x = -4 (x = -4,-5,-6,-7,-8,-9), the temperature (T(x) or y) does not change very much. Therefore, around those temperatures is a turning point, where the phase shift occurs from solid/liquid.

Logarithms are studied for which of the following​ reasons? A. To help in solving exponential equations when relating the bases
skad [1K]

Answer:

To help in solving exponential equations when relating the bases cannot be used

Step-by-step explanation:

Recall an equation of the form

a^{x}=b\\ from the expression a^{x}\\, a\\ is the base and the power is {x}\\.

a\neq b\\ it is impossible to carryout the operation since the bases are not equal.

This is where we implore the help of logarithm which help us to bring the base to a come base i.e using the property below

loga^{x}=logb\\x=\frac{logb}{loga} \\.

Hence we can conclude that logarithm helps in solving equations when bases cannot easily be related.

Phoebe took a survey of her classmates' favorite sport. The results are in the table below:
Komok [63]

The choose ( 0.25 )

Relative Frequency = Category Frequency / Total Frequencies

Category Frequency (prefer tennis) = 7

Total Frequencies = 28

Relative Frequency = 7 / 28

Relative Frequency = 0.25

I hope I helped you^_^

If 23/8, 11/2, 9/6, and 15/7 are placed in order from least to greatest, which would be first?
yarga [219]

Answer:

\frac{9}{6}

Step-by-step explanation:

The given fractions are;

\frac{23}{8},\frac{11}{2},\frac{9}{6},\frac{15}{7}

The least common denominator is 168.


We express all the fractions in equivalent form with the LCD as the denominator.


\frac{23}{8}=\frac{21\times23}{21\times8}=\frac{483}{168}


\frac{11}{2}=\frac{84\times11}{84\times2}=\frac{924}{168}


\frac{9}{6}=\frac{28\times9}{28\times6}=\frac{252}{168}


\frac{15}{7}=\frac{24\times15}{24\times7}=\frac{360}{168}


We now compare the equivalent forms and arrange from the least to the greatest.

\frac{252}{168}\:

This implies that,

\frac{9}{6}\:

Therefore the first would be \frac{9}{6}.
