Answer:

The Solution to the equation 4ˣ = 9.2 is the option D ) x = 1.60

Step-by-step explanation:

Given:

$4^{x}=9.2$

To Find:

x = ?

Solution:

We know Logarithmic identity as

$\log (A)^{B}= B\log A\\$

$4^{x}=9.2$ .............Given

Taking Log on both the side we have

$\log 4^{x}=\log 9.2\\\textrm{using the above identity we get}\\\\x\log 4 = \log 9.2\\\\x=\frac{\log 9.2}{\log 4} \\\\\therefore x =\frac{0.9637}{0.6020} \\\\\therefore x =1.6008\\\\\therefore x = 1.60$

The Solution to the equation 4ˣ = 9.2 is the option D ) x = 1.60

mr.sanchez bought 2 magazines for $9.95 each and 1 book for $14.95 if the sale tax is 6% what is the total cost mr.sanchez purch

In-s [12.5K]

(9.95x2)+14.95)=34.85

34.85x.06=2.09

34.85+2.09=36.94

so the total cost is 36.94$

Steven is moving to another city next weekend and wants to rent a moving truck. The rental rates for two companies in his area a

ASHA 777 [7]

Answer:

Company (1) charges $1.12 per mile and company (2) charges $0.85 per mile

Company (2) is $7.4 cheaper.

Step-by-step explanation:

From the tables given in the picture,

Let the equation representing the rental 'y' and distance traveled 'x' is represented by,

y = mx + b

For company (1),

Here m = per mile rental charges = Slope of the graph

b = Initial charges

Since slope of the line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

m = $\frac{y_2-y_1}{x_2-x_1}$

Therefore, slope of the line passing through (30, 53.55) and (60, 87.15) will be,

m = $\frac{87.15-53.55}{60-30}$ = $1.12 per mile

So the equation will be,

y = 1.12x + b

Since this line passes through (30, 53.55),

53.55 = 1.12(30) + b

b = 53.55 - 33.6

b = 19.95

So the expression representing charges for the company (1) will be,

y = 1.12x + 19.95

For company (2),

Per mile charges = slope of the line

m = $\frac{78-56.75}{50-25}$

m = $0.85 per mile

Equation for the charges will be,

y = 0.85x + b

Since this line passes through (25, 56.75),

56.75 = 0.85(25) + b

b = 56.75 - 21.25

b = 35.5

Therefore, equation representing total charges for company (2) will be,

y = 0.85x + 35.5

By comparing per mile charges,

Company (1) charges $1.12 per mile and company (2) charges $0.85 per mile

Steven plans to drive 85 km in rental truck.

Charges for company (1),

y = 1.12x + 19.95

y = 1.12(85) + 19.95

y = $115.15

Charges for company (2),

y = 0.85x + 35.5

y = 0.85(85) + 35.5

y = $107.75

Difference in charges of both the companies = 115.15 - 107.75 = $7.4

Therefore, company (2) is $7.4 cheaper.
