Edg vector operations, any help appreciated!
viktelen [127]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \: Add \:\: -6 \hat i - 6\hat j \:\:with \:\; Vector \:\; c

____________________________________

\large \tt Solution  \: :

Vector d can be represented as :

\qquad \tt \rightarrow \:  - 2 \hat i - 2 \hat j

Vector c can be represented as :

\qquad \tt \rightarrow \:  4 \hat i + 4\hat j

we have to create vector d from vector c

So, let's assume a vector x, such that sum of vector x and vector c equals to vector d

\qquad \tt \rightarrow \: x + ( 4 \hat i + 4 \hat j) =  - 2 \hat i  - 2 \hat j

\qquad \tt \rightarrow \: x  = -  ( 4 \hat i + 4 \hat j)   - 2 \hat i  - 2 \hat j

\qquad \tt \rightarrow \: x  = (-   4 \hat i  - 2 \hat  i)  + (  - 4 \hat j  - 2 \hat j)

\qquad \tt \rightarrow \: x  = - 6 \hat  i    -6 \hat j

Henceforth, in order to get vector d, we need to add (-6i - 6j) in vector c

Which equation(s) have x = –3 as the solution? log3(2x + 15) = 2 log5(8x + 9) = 2 log4(–20x + 4) = 3 logx81 = 4
baherus [9]

Answer:

log_3(2x+15)=2  and log_4(-20x+4)=3

Step-by-step explanation:

Plug it in and see!

log_3(2x+15)=2\\log_3(2(-3)+15)=2\\log_3(-6+15)=2\\log_3(9)=2\\\text{ This is a true equation because } 3^2=9\\\\\\log_5(8(-3)+9)=2\\log_5(-24+9)=2\\log_5(-15)=2\\\\\text{ Not true because you cannot do log of a negative number }\\\\log_4(-20(-3)+4)=3\\log_4(64)=3\\\text{ this is true because } 4^3=64\\\\\\log_x (81)=4\\log_{-3}(81)=4\\\text{ the base cannot be negative }\\\\\\\\\text{ There is only two options here} \\\\log_3(2x+15)=2 \text{ and } log_4(-20x+4)=3

Anastasy [175]

Answer:

Urban area = 58.27%

Suburban area = 34.83%

Rural area = 6.9%

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Total number of women = 290

Number of women in urban area = 169

Suburban area women = 101

Rural are women = 20

So, we can calculate the percentage of number of women from each area by using following formula,

Percentage = Women in specific area ÷ total women

So, percentage of Urban area = 169 ÷ 290 = 0.5827 or 58.27%

percentage of suburban area = 101 ÷ 290 = 0.3483 or 34.83%

percentage of rural area = 20 ÷ 290 = 0.0690 or 6.9%

Pie chart for the given information is attached below.

which of the following is the equation of the line that goes through the point (-4,-1) and has a slope of -3?
wel

Answer:

y = -3x - 11

Step-by-step explanation:

y - y1 = m(x-x1)

y - (-1) = -3(x-(-4))

y + 1 = -3(x+4)

y + 1 = -3x -12

y = -3x - 11
