Rewrite the following radical expressions as equivalent exponential expressions. b. 2(4√3)

Mathematics
1 answer:
IRISSAK [1]4 years ago
8 0

Answer:

2^{3} .3^{\frac{1}{2} }.

Step-by-step explanation:

Here in this problem, we have to rewrite a radical expression as an equivalent exponential expression.

The radical expression is 2(4√3)

Now, 2 ( 4√3)

=( 2 × 4) √3 {Since all the terms are in product form so, we can rearrange it}

= ( 2× 2²) × √3

=2³√3 {Since we know the formula from the property of exponent, xᵃ . xᵇ = x⁽ᵃ⁺ᵇ⁾ }

=2^{3} .3^{\frac{1}{2} }.

Therefore, 2^{3} .3^{\frac{1}{2} } is the required equivalent exponential form. (Answer)

Find the area of the isosceles triangle.​
Allushta [10]

Answer:

60in^2

Step-by-step explanation:

Area of a triangle = Height x Base X 1/2

Base = 10

Other 2 sides = 13

Now, let's split the Base into 2 parts.

=> 1 part = 5 and 2 part = 5

We can find the height using Pythagorean theorem

=> Isosceles triangle

=> (1 part of the base)^2 + Height^2 = The Hypotenuse^2  = the longer side of a triangle = 13^2

=> 5^2 + Height ^2 = 13^2

=> 25 + Height^2 = 169

=> 25 - 25 + Height ^2 = 169 - 25

=> Height^2 = 144

=> Height = Square root of 144

=> Height = 12

Area = 12 x 10 x 1/2

=> 12 x 5

=> 60 in^2

So, the Area is 60 in ^2

The sides of △FGH are FG = 6 x+ 7, GH = 8x - 5, and FH = 10x - 11. If the perimeter of △FGH is 87, list the angles in order from
irga5000 [103]

Answer:

From largest to smallest: FG, FH, GH

Step-by-step explanation:

Given

FG = 6x + 7

GH = 8x - 5

FH = 10x - 11

Perimeter = 87

Required

Order the sides in descending order

First, we need to solve for x.

Perimeter of FGH is calculated as thus:

Perimeter = FG + GH + FH

Substitute values for FG, GH, FH and Perimeter

87 = 6x + 7 + 8x - 5 + 10x - 11

Collect Like Terms

87 - 7 + 5 + 11= 6x + 8x + 10x

96= 24x

Reorder

24x = 96

Divide through by 24

x = 96/24

x = 4

Substitute 4 for x in FG, GH and FH

FG = 6x + 7

FG = 6 * 4 + 7

FG = 24 + 7

FG =31

GH = 8x - 5

GH = 8 * 4 - 5

GH = 32 - 5

GH = 27

FH = 10x - 11

FH = 10*4 - 11

FH = 40 - 11

FH = 29

In order of arrangement in descending order, we have:

FG =31    FH = 29     GH = 27
