vredina [299]

Answer:

the answer should be b. 259.56 inches because first of all remember the word perimeter that is adding all up the sides of a figures and remember the formula for the cirmuference is c=TTd and first of all you add 27+27 getting an answer of 54 so when you get that multiply 3.14 times 54 getting an answer of 169.56 and then you add 60+60 getting an answer of 120 because these sides are congruent meaning they are the same or have the same length and finally the last part is adding your answers which is 169.56 and 120 getting an answer of 289.56 so b is the correct and have a great day.

(Please show all work) 1. Find f(6) if f(x)= 1/2x + x - 4
dsp73

Answer:

\large\boxed{1.\ f(6)=5\ or\ f(6)=20}\\\boxed{2.\ d=5}\\\boxed{3.\ vertex=(-3,\ -1)}

Step-by-step explanation:

1.\\\text{Put x = 6 to the equation of a function}\ f(x):\\\\\text{If}\ f(x)=\dfrac{1}{2}x+x-4\to f(6)=\dfrac{1}{2}(6)+6-4=3+6-4=5\\\\\text{If}\ f(x)=\dfrac{1}{2}x^2+x-4\to f(6)=\dfrac{1}{2}(6^2)+6-4=\dfrac{1}{2}(36)+2=18+2=20\\\\2.\\\text{The formula of a distance between two points:}\\\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\\text{We have the points (2, -4) and (5, -8). Substitute:}\\\\d=\sqrt{(5-2)^2+(-8-(-4))^2}=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5

3.\\\text{The vertex formula of a parabola:}\\\\y=a(x-h)^2+k\\\\(h,\ k)-vertex\\\\\text{We have}\ y=(x+3)^2-1=(x-(-3))^2-1\\\\\text{Therefore the vertex is:}\ (-3,\ -1).

bills normal temperature is 98.6 today ballistic and has a temperature of 104.3 how many degrees above his normal temperature is
kkurt [141]

Answer:

Today's temperature is 5.7 degrees above Bill's normal temperature.

Step-by-step explanation:

Given

Represent the normal temperature with N and today's temperature with T.

Such that:

N = 98.6

T = 104.3

Required

Determine the temperature above the normal temperature

The interpretation of this is to calculate the difference between Bill's normal temperature and Bill's today temperature.

Represent the difference with D

D is calculated as follows:

D = T - N

Substitute values for T and N

D = 104.3 - 98.6

D = 5.7

Hence, today's temperature is 5.7 degrees above Bill's normal temperature.
