Mathematics
1 answer:
wolverine [178]3 years ago
4 0

Answer:

x = ± \sqrt{\frac{f}{m} }

Step-by-step explanation:

Given

mx² = f ( isolate x² by dividing both sides by m )

x² = \frac{f}{m} ( take the square root of both sides )

x = ± \sqrt{\frac{f}{m} }

The figure shows part of the concrete slab which is used to make drains and its cross-section. it is made up of a cuboid of dime
Arlecino [84]

(i) The area of the cross section ABCDEFG is 1771.6cm³

(ii) The volume of the concrete lab is 212592 cm³

(iii) the total surface area of the concrete slab is 30284 cm²

(iv) The mass of the concrete slab is 40746.8 kg/m³.

Given, dimensions are 120 cm by 60 cm by

40 cm.

(i) area of cross section = 40 × 60 ₋ π(60 ₋10 ₋ 10)/2 . 1/2

                                     = 1771.6 cm³

(ii) the volume of the concrete slab = 40 × 60 × 120 ₋ 1/2 π((60 ₋ 10   ₋10)/2)² . 120

= 212592 cm³

(iii) The total surface area is:

=40 × 120 × 2 ₊ 60 × 120 ₊ 1771.6 × 2 ₊ 10 × 120 × 2 ₊ 1/2 π(60 ₋ 10 ₋10) × 120

= 30284 cm²

(iv) Mass of the concrete slab given density is 2300 kg/m³

Mass = Volume × density

Mass = 17.716 m³ ×  2300

         = 40746.8 kg/m³

Hence we get the mass as 40746.8 kg/m³.

PLS HELP ME WITH THIS !!
Mashutka [201]
Part 1:
180 = 5p+98 + 9p-2
180 = 14p + 96
84 = 14p
6 = p

part 2:
angle S will be the same as angle Q, so:
9p-2
9(6)-2
54-2
M
