Mathematics
1 answer:
AVprozaik [17]4 years ago
5 0

Answer:

Option A and D are only true.

Step-by-step explanation:

The equation is given as 2 (4x + 1) -3 = ax + b

⇒ 8x - 1 = ax + b ....... (1)

A. If a = 8 and b = 1, then the equation will have no solution.

D. If a = 2 and b = - 1, then the equation (1) will have exactly one solution.

All the remaining conditions and statements are false.

Therefore, options A and D are only true. (Answer)

What is the area of the figure:
Luba_88 [7]

For this case we have that the area of the triangle is given by:

A = \frac {b * h} {2}

Where:

b: It's the base

h: It's the height

We have to:

cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}

The atura will be given by:

sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}

So, the area is:

A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144

Answer:

144

Hello!

To find the slant height you use the equation

a^2 + b^2 = c^2

a is radius
b is height
c is slant height

Put in the values you know

9^2 + 17^2 = c^2

square the numbers

81 + 289 = c^2

Add

370 = c^2

Take the square root of the number

19.2 = c

The answer is B)19m

Hope this helps!
