Solution set of 6x2=13x+5

Mathematics
1 answer:
Lena [83]3 years ago
6 0

Answer:

x = -1/3         x = 5/2

Step-by-step explanation:

6x^2=13x+5

Subtract 13x from each side

6x^2-13x=13x-13x+5

6x^2-13x=5

Subtract 5 from each side

6x^2-13x-5=5-5

6x^2-13x-5=0

Factor

(3x+1   )(2x  -  5 ) =0

Using the zero product property

3x+1 =0    2x-5 =0

3x=-1          2x =5

x = -1/3         x = 5/2

A boat traveling upstream goes 84 kilometers in 7 hours. If the return trip takes only 3 hours, what is the speed (in kilometers
Hunter-Best [27]
Speed = Distance ÷ time 

Speed upstream = 84 ÷ 7 = 12 km/h

Speed downstream = 84 ÷ 3 = 28 km/h

Speed in still water = 1/2(28 + 12) = 20 km/h

Answer: 20 km/h

What additional information is obtained by measuring two individuals on an ordinal scale compared to a nominal scale
velikii [3]

The direction of the difference between the 2 measurements.

<h3>What is nominal and ordinal scale with example?</h3>
  • Examples of data for a nominal scale include a person's gender, ethnicity, and hair color.
  • On the other hand, an ordinal scale requires putting data in a certain order, or in relation to one another and "ranking" each parameter (variable).

<h3>What is the difference nominal and ordinal?</h3>
  • Ordinal data has a preset or natural order, whereas nominal data is categorized without a natural order or rank.
  • A number that can be measured, however, will always be present in numerical or quantitative data.

<h3>What is an example of a ordinal scale?</h3>
  • First place would go to a student with a score of 99 out of 100; third place would go to a student with a score of 92 out of 100; and so on.

Una pelota sale disparada desde el nivel del suelo, con una velocidad de 40 m/s y un ángulo de elevación de 50°. a) Calcule la a
DedPeter [7]

Respuesta:

Los 47.85m

Explicación paso a paso:

Altura máxima = u²sin²Ф / 2g

Dado

velocidad u = 40 m / s

Ф = 50 °

g = 9,81 m / s²

Sustituir'

H = 40²sin²50 / 2 (9,81)

H = 1600 (0,7660) ² / 19,62

H = 1600 (0,5868) /19,62

H = 938,8096 / 19,62

H = 47,85 m

Por lo tanto, la altura máxima es de 47,85 m.

I’ll give you brainliest for the first person with an answer
raketka [301]

Answer:

1296mm^2

Step-by-step explanation:

Surface Area of the Rectangular Prism to the left on top of the box:

Area of square = lw, 9mm * 9mm = 81mm, then multiply by 2 because 2 of the squares are a part of the surface, giving <u>162mm^2</u>

Area of a rectangle =lw, 9mm * 9mm = 81mm, then multiply by 2 again, because 2 rectangles are a part of the surface, giving <u>162mm^2</u>

So, the total surface area of the rectangular prism to the left on top, is 324mm^2

Surface Area of the Triangular Prism:

Area of a triangle: 1/2bh, and our base length would be 12, because we have to subtract 9 from 21 since the base length of the triangle isn't stated. Anyways, A = 1/2bh, so A = 1/2(12)(9) = 54mm^2, but multiply by two, so we get <u>108mm^2</u>.

Area of the rectangle: lw, so 15mm * 9mm = <u>135mm^2</u>

So, the total surface area of the triangular prism is 243mm^2

Surface Area of the Rectangular Prism at the bottom:

Area of the long rectangles in front = lw, 21mm * 9mm = 189mm^2, multiply by 2, <u>378mm^2</u>

Area of the rectangles to the side = lw, 9mm * 9mm = 81mm^2, multiply by 2, <u>162mm^2 </u>

Area of the rectangle at the very bottom = lw, 21mm * 9mm = <u>189mm^2</u>

So, the total surface area of the rectangular prism at the bottom is 729mm^2

Add all the total surface areas of each shape to get the total surface area of the figure:

324mm^2 + 243mm^2 + 729mm^2 = 1296mm^2

The surface area of the figure above is 1296mm^2
