Evaluate f(−3) for f(x)=2x2−x+5.

Answer:

positive is the correct answer

Answer: it’s A

Step-by-step explanation:

I just took the test

The graph of f(x) is shown by figure A.

We have given that the  function,

[tex]f(x)=log_2x[/tex]

We have to determine the graph ofthe given function

We have to find the co-ordinate of the given finction

We have to put one variable value that is any real number and by using this value find the value of another variable.

[tex]y=f(x)=log_2x[/tex]

[tex]y=log_2x[/tex]

Put x=1

[tex]y=log_2(1)\\y=0[/tex]

We get the point A(1,0)

put x=2

[tex]y=log_2(2)\\y=1[/tex]

We get the point B(2,1)

Put x=4

[tex]y=log_2(4)\\y=2[/tex]

We get the point C(4,2)

So we plot this point on coordinate system so we get the graph

as shown below

Therefore  the option  A is correct.

Answer: 9/24km

Step-by-step explanation:

Since we are informed that Ana can bike 9 kilometers in 24 minutes.

To calculate the distance that Ana can bike in 1 minute will be gotten by dividing the distance covered divided by the time taken. This will be:

= 9/24 km

Therefore, Anna can bike 9/24km in 1 minute.

The shape of this figure is a sphere

Step-by-step explanation:

Have a good day :)

Step-by-step explanation:

the figure is a sphere shape

Answer:  I believe the correct answer from the choices listed above is the third option. The base shape of a cylinder would be circle. A cylinder is a closed solid that has two parallel (usually circular) bases connected by a curved surface.

Hope this answers the question. Have a nice day.

The base shape of the cylinder is a circle, the correct option is D.

A cylinder is a three dimensional figure made up of parallel circular discs.

The best shape of the base of a cylinder can be a circle only.

The cylinder has two circular bases as the surface joining the two bases is curved and has the same radius as the base.

Answer:

A.

Step-by-step explanation:

Take a look at what happens when squaring either of these...

[tex](ax-by)^2=(ax-by)(ax-by)=a^2x^2-2abxy+b^2y^2\\\\(ax+by)^2=(ax+by)(ax+by)=a^2x^2+2abxy+b^2y^2\\[/tex]

Notice a couple of patterns.

1.  The last term has a positive coefficient.  That rules out answer choices C and D.

2.  The coefficient of the middle term is either [tex]+2ab \text{ or } -2ab[/tex] .  So what are a  and b?  a is the square root of the x^2 term and b is the square root of the y^2 term.

[tex]25x^2 \Rightarrow a=5\\\\9y^2 \Rightarrow b=3\\\\ab=15\\\\2ab=30[/tex]

The middle coefficient needs to be either +30 or -30.  The answer is choice A.

Answer:

[tex]distance = \sqrt{(x_{1} -x_{2})^2+(y_{1} -y_{2})^2 }[/tex]

Step-by-step explanation:

From B on the ground straight up to A and then turn the corner to follow the dotted line...that is a 90 degree angle. So in order to find the angle of depression, subtract 66 from 90 to get 24 degrees. Subsequently, that is also the angle of elevation (the base angle inside the triangle) due to parallel lines and whatnot.

B. {7.88}

Step-by-step explanation:

[tex]\frac{6}{x}= \frac{10}{6}[/tex]

x · 10 = 6 · 6

10x = 36

10x ÷ 10 = 36 ÷ 10

x = 3.6

[tex]\frac{9}{8} =\frac{x}{7}[/tex]

8 · x = 9 · 7

8x = 63

8x ÷ 8 = 63 ÷ 8

[tex]x=7\frac{7}{8}[/tex] or x = 7.875

7.875 rounded to the nearest tenth is 7.88.
