Answer:

35*2 = 70

70 mph on the Major Highway

Step-by-step explanation:

Answer:

70

Step-by-step explanation:

if 35 is half of x (x being the speed of a major interstate highway a few miles away) then this means [tex]\frac{x}{2} =35[/tex] you multipliy both sides by 2 to get x by its self and now have x=70

Answer:

∠ YZX ≈ 19.7°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinZ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{YZ}[/tex] = [tex]\frac{7.5}{22.3}[/tex] , then

∠ YZX = [tex]sin^{-1}[/tex] ([tex]\frac{7.5}{22.3}[/tex] ) ≈ 19.7° ( to 3 significant figures )

Answer:

m<ACD = [tex]50^{o}[/tex]

Step-by-step explanation:

From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.

In the triangle ACD:

<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)

<ACD + 40 + 90 = 180

<ACD + 130 = 180

<ACD = 180 - 130

<ACD = [tex]50^{o}[/tex]

With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is [tex]50^{o}[/tex].

x=NEGATIVE 1/2, POSITIVE 2

Step-by-step explanation:

Just use math.waycom

The non-negative zero of the function f(x) is x = 2.

The zero of the function is where the y-value is zero. The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

here, we have,

For a given function f(x), the "zeros" of the function are the values of x such that:

f(x) = 0

In this case, we have the function:

f(x) = 6*x^2 - 9*x - 6

If we want to find the zeros of this function, we need to solve:

f(x) = 0 =  6*x^2 - 9*x - 6

To solve this, we can use the Bhaskara's formula, which says that for a general quadratic equation:

0 = a*x^2 + b*x + c

The zeros are:

x = -b ±√b² - 4ac / 2a

In this case our equation is:

0 =  6*x^2 - 9*x - 6

then, in the above notation, we have:

a = 6

b = -9

c = -6

Replacing these in our general formula, we get:

x = 9±15 /12

Then we have two zeros:

x = (9 + 15)/12 = 24/12 = 2

x = (9 - 15)/12 = -6/12 = -1/2

But we want only the non-negative, so we can discard the second one.

Concluding, the non-negative zero of the function f(x) is x = 2.

Answer:

Step-by-step explanation:

Ratio = 4/7 : 1/8

        [tex]=\frac{\frac{4}{7}}{\frac{1}{8}}\\\\=\frac{4}{7}*\frac{8}{1}\\\\=\frac{32}{7}[/tex]

       = 32 : 7

[tex]\frac{\frac{1}{8}}{\frac{4}{7}}=\frac{1}{8}*\frac{7}{4}\\\\=\frac{7}{32}[/tex]

= 7 : 32

Ratio 4/7 over 1/8  is the multiplicative inverse of the ratio 1/8 over 4/7

Answer: 15 sq. units

Step-by-step explanation:

Given

[tex]f(x)=\ln (2)2^x[/tex]

The area bound by it from x=0 to x=4

Using integration

[tex]I=\int_{0}^{4}f(x)dx[/tex]

[tex]I=\int_{0}^{4}\ln(2)2^xdx[/tex]

[tex]I=\left [ \dfrac{\ln (2)2^x}{\ln (2)} \right ]_0^4[/tex]

[tex]I=\left [ 2^x \right ]_0^4[/tex]

[tex]I=2^4-2^0\\I=16-1=15\ sq.units[/tex]

Step-by-step explanation:

1 full container = 18 Liters.

The amount in the container = 7 2/3

The amount left to go is 18 - 7 2/3

Now I don't know how you have been taught to do this, but I think the easiest way is to make 18 = 17 3/3  If you do that then the 5 will be subtracted from the 17 and the 2/3 will be subtracted from the 3/3

17 - 5 = 12

3/3 - 2/3 = 1/3

So the answer is 12 1/3

Answer:

They are both correct. When the fractions are added, the sum is 4/6. 4/6 is not in its simplest form yet. It can be simplified by dividing the numerator and the denominator by 2. When divided by 2, it yields 2/3

Step-by-step explanation:

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{6}[/tex]

[tex]\frac{3 + 1}{6}[/tex] = 4/6 = 2/3

Answer:

A. 7

Step-by-step explanation:

The slope is 12 and y- intercept is -5.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y=12x−5

Now, from slope- intercept form

y = mx + b

where m is the slope and b is the y intercept.

Now, Comparing with given equation

m= 12 and b= -5

Hence, the slope is 12 and y- intercept is -5.
