Find the area of the shaded region in square units. Show your reasoning.
Answer:
40 square units
Step-by-step explanation:
First of all, lets say that square has side [tex]l[/tex], so, the area unit is [tex]l^2[/tex]
the diagonal's square is [tex]l\sqrt{2}[/tex]
CALCULATION OF TRIANGLES'S AREA (there are 4 triangles)
[tex]A_{triangles}=4*base*heigh*0.5=2*(l\sqrt{2} )(2l\sqrt{2} )=8l^2[/tex]
CALCULATION OF MAIN SQUARE AREA
[tex]A_{square}=side*side=(4\sqrt{2} l)(4\sqrt{2} l)=32l^2[/tex]
TOTAL AREA
[tex]A_{total}=A_{triangles}+A_{square}=8l^2+32l^2=40l^2[/tex]
Give the slope and the y-intercept of the line y=6x – 1. Make sure the y-intercept is written as a coordinate.
Answer:
slope = 6
y-intercept is (0,-1)
Step-by-step explanation:
the equation y = 6x-1 is written in slope-intercept form so it's easy to find the slope and the y-intercept

Find the slope of the line passing through these points (-3,4) and (4,1)
Answer:
-3/7
Step-by-step explanation:
To find the slope use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 1-4)/(4 - -3)
= (1-4)/(4+3)
= -3/7
Answer:
slope = - 3/7
step-by-step explanation:
we have two points which are (-3,4) and (4,1).
To find the slope of line , use the slope formula which is
m = ( y² - y¹ ) / ( x² - x¹)
Where,
m = slope( y² - y¹ ) = ( 1-4 ) ( x² - x¹) = ( 4 - ( - 3 ) )substitute the values
m = ( 1 - 4 ) / ( 4 - ( - 3 ))
m = -3 / 7
Hence, slope is -3/7.

Answer:
P: $0.12/kWh; M: $0.15/kWh
$285 from company P
Step-by-step explanation:
The cost per kWh from Company P is found by dividing the cost by the corresponding number of kWh:
$150/(1250 kWh) = $0.12/kWh
The cost per kWh from Company M is the coefficient of x in the equation:
$0.15/kWh
__
Company P provides power for a lower cost. The cost from Company P for 2375 kWh is ...
(2375 kWh)×($0.12/kWh) = $285 . . . cost for 2375 kWh

9514 1404 393
Answer:
349
Step-by-step explanation:
In Roman numerals, C=100, L=50, X=10, V=5, I=1. Values are additive except when a lower value precedes a higher value. In that case, the lower value is subtracted.
The value here is 10 -1 +50 -10 +100 +100 +100 = 349.
__
Additional comment
Letters are assigned to 1 and 5 and those values multiplied by 10 or 100. When you get to 4000 and above, special forms apply. By convention, only unit values within a factor of 10 are subtracted. In the above number, 49 is written XLIX, not IL.

D. Why is the interest earned in part (c) not twice the amount earned in part (a)?
Answer:
1628.89
2593.74
2653.30
Because the interest forms an exponential function. This means that the amount of interest earned in each period is increasing and should therefore be more than double.
Step-by-step explanation:
A: 1000*(1.05)¹⁰= 1628.89
B: 1000(1.1)¹⁰= 2593.74
C: 1000(1.05)²⁰= 2653.30
D: Because the interest forms an exponential function. This means that the amount of interest earned in each period is increasing and should therefore be more than double.

maya raised 286.00
lian raised 192.84 less than maya
rei earned 113.25 more than lian
what is the total amount of money raised by all three?
Answer:
585.57
Step-by-step explanation:
Maya got 286.00
if lian got 192.84 less than we do 286-192.84 which is 93.16
if lian got 93.16, we add 113.25 to 93.16 to get rei's amount.
113.25 + 93.16 = 206.41
Now we add all their amounts, 286+93.16+206.41
585.57
find the additive inverse and multiplicative inverse of a 5
Answer:
ans: additive inverse is -5
multiplicative inverse is 1/5
Step-by-step explanation:
adding what value to 5 makes it 0 i.e
5 + (- 5)= 0 ( so additive inverse is -5)
multiplying what value to 5 makes it 1 i.e
5×( 1/5)=1 ( so multiplicative inverse is 1/5)
