The first statement will be "<em><u>false</u></em>" and the second one is "<em><u>true</u></em>". A further explanation is below.

According to the question,

Number of bacteria after "t" hours,

= 50\times (3)^{\frac{t}{8} }

This will be false.

Now,

After 36 hours,

→ N = 50\times (3)^{\frac{36}{8} }

       = 50\times (3)^{\frac{36}{8} }

       = 50\times (3)^{4.5}

       = 7015

This will be true.

Which is the graph of f(x) = -(x + 3)(x + 1)?
ch4aika [34]

Answer:

Step-by-step explanation:

x intercepts are -3,-1

f(x)=-(x²+x+3x+3)=-(x²+4x)-3=-(x²+4x+4-4)-3=-(x+2)²+4-3

or f(x)=-(x+2)²+1

vertex is (-2,1)

so it is an inverted  parabola with vertex (-2,1) and x-intercepts (-3,0) and (-1,0)

Baseball hat is on sale for 15% off, which is $2.70. How much does the baseball hat cost at full price?
lidiya [134]

Answer:

27.9 dollars

Step-by-step explanation:

2.70= 15 percent

2.70x2=5.4=30 percent

5.4+2.70=8.1=45 percent

8.1x2=16.2=95 percent

95 percent + 15 percent=18.9

18.9=105 percent

in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3

which = .9

18.9+9=27.9

100 percent is 27.9 dollars
