It is Given that f(x) = log₁₀(x) then the value of f(50) is 1.70.

Logarithmic functions are defined as the inverses of exponential functions.

Hence, exponential functions can be expressed in logarithmic form

Given that f(x) = log₁₀(x)

we need to find the value of f(50),

we have to substitute x to be 50 in the logarithm function,

f(50) = log₁₀(50)

f(50) = log₁₀(5 x 10)

f(50) = log₁₀(5) + log₁₀(10)  

f(50) = 1 + log₁₀(5)

f(50) = 1 + 0.70

f(50) = 1.70

Hence, It is Given that f(x) = log₁₀(x) then the value of f(50) is 1.70.

Answer:

I think it's the one in the middle

Step-by-step explanation:

Answer:

Step-by-step explanation:

Because the slope of y = 2x + 3 is 2, y increases by 2 for every unit increase in x.

Substituting the given x-value -2 into y = 2x + 3 results in y = -1.

If we now increase x by 1, from -2 to -1, y increases by 2:  the new

y value is y = -1 + 2 or y = 1. which agrees with the +1 in the list of y-values.

Again, y =  ?,,,1,,,,?,,?,,7,,?  becomes  y = -1, 1, ?,,?,,7.  Note that -1 + 2 = 1;

1 + 2 = 3; 3 + 2 = 5; 5 + 2 = 7 (which agrees with the given 7); 7 + 2 = 9.

So the given incomplete table of values

x,,-2,,-1,,0,,1,,2,,3

y,,,?,,,1,,,,?,,?,,7,,?

becomes:

x,,-2,,-1,,0,,1,,2,,3

y,,, -1,,1,,,3,,5,,7,,9

Option A is the correct option. The polynomial correctly combines the like terms and expresses the given polynomial in standard form is,

f(m,n) = n⁶+7mn⁵+14m²n⁴-5m³n³-6m⁶-2m⁶

A polynomial equation is an equation in which the unknown variable is one and the highest power of the unknown variable is n. Here n can be any real number.

Given information-

The polynomial equation given in the problem is,

8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³

Let the above polynomial is. Thus,

f(m,n) = 8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³

The terms with the same base and exponents can be added or subtracted from each other. Thus solve the equation further as,

f(m,n) = ( 8mn⁵ - mn⁵ ) -2m⁶ + ( 5m²n⁴+9m²n⁴ ) - ( m³n³-4m³n³) + n⁶-4m⁶

f(m,n) = 7mn⁵ - 2m⁶ + 14 m²n⁴ - 5 m³n³ + n⁶- 6m⁶

Arrange it as,

f(m,n) = n⁶+7mn⁵+14m²n⁴-5m³n³-6m⁶-2m⁶

Thus the polynomial correctly combines the like terms and expresses the given polynomial in standard form is,

f(m,n) = n⁶+7mn⁵+14m²n⁴-5m³n³-6m⁶-2m⁶

Answer:

t = 6

∠BAC = ∠EAD = 6°

∠BCA = ∠ABC = ∠AED = ∠EDA = 87°

Step-by-step explanation:

From inspection of the diagram, we can see that there are 2 triangles inside a circle.  One of the vertices of both triangles is at the center of the circle. The other vertices of both triangles are on the circumference of the circle.

The dashes on the line segments (chord) mean they are equal in length.

⇒ BC = DE

The legs of both triangles are the radius of the circle.

Therefore, ΔABC = ΔAED

This means the ∠BAC = ∠EAD, therefore:

⇒ 6t - 12 = 18 - 4t

⇒ 10t - 12 = 18

⇒ 10t = 30

⇒ t = 3

Substituting the found value of t into one of the expressions to find ∠BAC and ∠EAD:

⇒ ∠BAC = ∠EAD = 6(3) - 12 = 6°

Triangles ΔABC and ΔAED are both isosceles triangles (as they have 2 sides of equal length: the radii).

Therefore, the remaining 2 angles in each triangle will be equal.

The sum of interior angles of a triangle = 180°

⇒∠BAC + 2(∠BCA) = 180°

⇒ 6° + 2(∠BCA) = 180°

⇒ 2(∠BCA) = 174°

⇒ ∠BCA = 87°

Therefore, as ∠BCA = ∠ABC = ∠AED = ∠EDA

all the other angles are 87°

Answer:

363.22

Step-by-step explanation:

Method 1:

You could find the whole figure surface area than divided by 1/2

Method 2: (the one I'm going to personally be doing)

Break the figure into two rectangular figures

Formula for surface area of rectangular prism:

A = 2(width x length + height x length + height x width)

Figure 1:

A = 2(width x length + height x length + height x width)

height = 3.8 yd

length = 10.1 yd

width = 4.3 yd

A = 2((4.3) x (10.1) + (3.8) x (10.1) + (3.8) x (4.3))

A = 2(98.15)

A = 196.3

Figure 2:

A = 2(width x length + height x length + height x width)

height = 8.4 yd

length = 10.1 yd

width = 2 yd

A = 2((2) x (10.1) + (8.4) x (10.1) + (8.4) x (2))

A = 2(121.84)

A = 243.68

There is overlapping surface area that shouldnt be include so we need to subtract it...

For one face of figure 1

3.8 x 10.1 = 38.38

Total:

Figure 1 + Figure 2 - 2(one face)

196.3 - 38.38 = 157.92

243.68 - 38.38 = 205.3

205.3 + 157.92 = 363.22

The ratio of the days it rained to number of days is 3 : 7

The proportion of the number of days it rained is given as:

Proportion = 3/7

This means that:

Proportion = Days it rained/Total number of days.

So, we have:

Days it rained/Total number of days = 3/7

Express as ratio

Days it rained : Total number of days = 3 : 7

Hence, the ratio is 3 : 7

Divide the shape into 2.

Area of a rectangle= Length * Width
