Your graph looks wrong to me because from the point (0,4) you should count down 1 and over 2 ( it looks like you did down 1 over 4)
13b. Y= -1/2x-3
I’m not sure on 13c though
sorry :(

vladimir1956 [14]

Answer:

16  sq. units

Step-by-step explanation:

<u>The formula for the area of a triangle:</u>

  • A = 1/2bh

<u>If base and height are known as:</u>

  • b = 8 units and h = 4 units

<u>Then the area is:</u>

  • A = 1/2*8*4 = 16 sq. units

Find the distance between the points (6,5√5) and (4,3√2).<br> 2, 2√2, 2√3
FromTheMoon [43]

Answer:

D=\sqrt{(147-30\sqrt{10}}

Step-by-step explanation:

Here we are required to find the distance between two coordinates. We will use the distance formula to find the distance

The distance formula is given as

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Here we are given two coordinates as

(6,5\sqrt{5} ) , (4,3\sqrt{2} )

Substituting these values in the Distance formula given above we get

D=\sqrt{(6-4)^2+(5\sqrt{5} -3\sqrt{2}) ^2}

D=\sqrt{(2)^2+(5\sqrt{5})^2+(3\sqrt{2})^2-2*5\sqrt{5}*3\sqrt{2}}\\

D=\sqrt{4+125+18-2*15\sqrt{10}}\\D=\sqrt{147-30\sqrt{10}}\\

Hence this is our answer

Use synthetic division to divide (x3 + 12x2 + 38x + 26) ÷ (x + 4)
KengaRu [80]
Divisor is -4
Use coefficients 1    12    38    26

Bring down 1 multiply by -4 and add to 12 =8
Multiply 8 by -4 and add to 38 = 6 
Multiply 6 by -4 and add to 26 = 2 which is the remainder

looks like     1    12    38    26
                          -4   -32   -24
                    ________________
                     1     8      6     R 2
so answer A of x squared + 8x + 6 +R2 is correct

Please help me with this. Please!
jonny [76]

Answer:

214

Step-by-step explanation:

A circle is 360 degrees

Arc EF is 146 degrees

EF + EDF = full circle

146 + EDF = 360

Subtract 146 from each side

146-146 +EDF = 360-146

EDF =214
