Answer:

1) 63cm²

2) 268cm²

Step-by-step explanation:

1) Middle Rectangle = 4 × 3 = 12

Little 'arms' = ( 1×1 ) × 2 = 2cm²

12+2 = 14cm² removed in total

Original size: 11 × (2+1+2+2) (which is 7) = 77cm²

77cm² - 14cm² = 63cm² left.

2) Left extruding part = 4 × 2 = 8cm²

Middle part = 4 × 6 = 24cm²

Right extruding part = 2 × 4 = 8cm²

In total 8 + 24 + 8 = 40cm² removed

Original area = 22 × ( 4+2+2+2+4 ) (which is 14) = 308cm²

308cm²- 40cm² = 268cm² left

Hope this helps!

Calculate (A⃗ ×B⃗ )⋅C⃗ for the three vectors A⃗ with magnitude A = 5.08 and angle θA = 25.6 ∘ measured in the sense from the +x

alexgriva [62]

Answer:

(A⃗ ×B⃗ )⋅C⃗ = - 76.415

Step-by-step explanation:

First we need to calculate (A⃗ ×B⃗ ) :

(A⃗ ×B⃗ ) = A.B.sin (α).n

Where A is the magnitude of A⃗

Where B is the magnitude of B⃗

Where α is the angle between A⃗ and B⃗ = 63.9 - 25.6 = 38.3

Finally n is the vector orthogonal to A⃗ and B⃗

n magnitude is 1 and his direction is given by the right hand-rule

so n = ( 0 , 0 , 1 )

(A⃗ ×B⃗ ) = A.B.sin (α).n = 5.08 . 3.94 . sin (38.3) . (0 , 0 , 1 ) = (0,0,12.4)

C⃗ can be written as C.(0,0,-1) because of his +z - direction

C.(0,0,-1) = 6.16.(0,0,-1) = (0,0,-6.16)

(A⃗ ×B⃗ )⋅C⃗ = (0,0,12.4).(0,0,-6.16) = -76.41480787 = -76.415

The density of aluminum is 2.375 grams per cubic centimeter. Find the volume of a portion of a sheet of aluminum that has a mass

Rufina [12.5K]

This is the concept of density, volume and mass of different materials; To calculate for the volume of an aluminium material with density of 2.375 grams per cubic centimeter and a mass of 0.78 Kilogram we proceed as follows;
Density=mass/volumemaking volume the subject we get;volume=mass/densitythus;mass=0.78 kg= 780 gdensity=2.375 g/cm^3Hence,volume=780/2.375=328.421 cm^3

Which graph correctly solves the system of equations below? <br> y=-x^2+1 <br> y=x^2-4

KIM [24]

Red line shows
y=x^2-4 , cause it's going through point (0,-4)

So blue line shows
y= -x^2+1 Point (1,0) belong to it , moreover x factor is negative , so the arms of parabola will go down

Have nice evenig :)
