Can someone plz help me

Given:

The given function is

[tex]f(x)=112-kx[/tex]

[tex]f(-3)=121[/tex]

To find:

The value of k.

Solution:

We have,

[tex]f(x)=112-kx[/tex]

Putting x=-3, we get

[tex]f(-3)=112-k(-3)[/tex]

[tex]121=112+3k[/tex]                   [tex][\because f(-3)=121][/tex]

Subtract both sides by 112.

[tex]121-112=3k[/tex]

[tex]9=3k[/tex]

Divide both sides by 3.

[tex]\dfrac{9}{3}=k[/tex]

[tex]3=k[/tex]

Therefore, the value of k is 3.

Given

Coordinates of Old oak tree are (3,7)

Coordinates of granite boulder are (-2,6)

Distance between them is given by distance formula i.e.

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between them is

[tex]\Rightarrow d=\sqrt{(-2-3)^2+(6-7)^2}\\\Rightarrow d=\sqrt{(-5)^2+(-1)^2}\\\Rightarrow d=\sqrt{25+1}=\sqrt{26}\approx 5.09\ \text{units}[/tex]

Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

[tex]A=6*\frac{1}{4} ^2\\\\A=6*\frac{1}{16} \\\\A=\frac{6}{16} \\\\A=\frac{3}{8}[/tex]

Answer:

[tex]A = \frac{3}{8}ft^2[/tex]

Step-by-step explanation:

Using the given formula, [tex]A=6s^2[/tex], and the given value for the side length of the cube, [tex]\frac{1}{4}[/tex] foot, substitute the given value into the equation and solve.

[tex]A=6(\frac{1}{4})^2[/tex]

Remember, setting any value to the second power is the same as multiplying the base (the value that is being squared) by itself. Apply this information to the given problem,

[tex]A = 6(\frac{1}{4}*\frac{1}{4})\\\\A = 6(\frac{1}{16})\\\\A = \frac{6}{16}\\\\A = \frac{3}{8}[/tex]

Step-by-step explanation:

Answer:

10e + 3 < 92

Step-by-step explanation:

Any number times ten plus three is less than 92. Like e = 3, which would be 10(3)+3, or 33. Any number that would make the statement true can be used in the place of e.

Answer: 53 points

Step-by-step explanation:

Let the number of points gotten by Kate be represented by x.

Since we are given the information that Kevin got 52 points which was 54 points less than 2 times that of kates points. This can be formed into an equation as:

(2 × x) - 54 = 52

2x - 54 = 52

2x = 52 + 54

2x = 106

x = 106/2

x = 53

Kate got 53 points
