Answer:

15

Step-by-step explanation:

You would divide 2 by 12 first and then multiply it by 90.

Answer:

Step-by-step explanation:

90 * (2 ÷ 12)

90 *([tex]\frac{1}{6}[/tex])

90*1/6

90/6

15

therefore 15 is the required answer.

Using the logarithmic function, it is found that the predicted number of views of the video after 3 days is of 57.

The function that represented the relationship between the time in days and the number of views is given by:

[tex]\ln{v} = 0.81\ln{t} + 3.15[/tex]

We want the number of views after 3 days, thus, [tex]t = 3[/tex], and we have to solve for v.

[tex]\ln{v} = 0.81\ln{3} + 3.15[/tex]

[tex]\ln{v} = 0.89 + 3.15[/tex]

[tex]\ln{v} = 4.04[/tex]

[tex]e^{\ln{v}} = e^{4.04}[/tex]

[tex]v = 57[/tex]

57 views.

Answer:

c. y=x^2+2x-7

Step-by-step explanation:

A linear function has the highest power of 1   (x)

A quadratic has the highest power of 2  (x^2)

A cubic has the highest power of 3  ( x^2)

a. y=x+9  linear

b. y=2x-15  linear

c. y=x^2+2x-7  quadratic

d. y=x^3-x^2 cubic

Quadratic Function is the equation that takes form of:

[tex] \large \boxed{y = a {x}^{2} + bx + c}[/tex]

where a, b and c both are real number and a ≠ 0.

The first and second choices are linear equation because it's in the form of y = mx+b.

The last choice is a cubic equation since it has the third degree x³.

Remember that the quadratic equation can be ax²+bx+c = 0 or y = ax²+bx+c only.

Answer

Answer:

h = 50 inches

Step-by-step explanation:

To find the value of h, we are to use the appropriate trigonometric ratio

The given angle faces the unknown length and that makes the unknown length the opposite side

The given side faces the right angle and that makes it the hypotenuse

The trigonometric ratio that connects the opposite and the hypotenuse is the sine

The sine of an angle is the ratio of the opposite side to the hypotenuse

Thus, we have it that;

sin 23 = h/129

h = 129 * sin 23

h = 50 inches

Answer: The percentage of male students who are between 145 cm and 170 cm = 98.71%

Step-by-step explanation:

Let x denotes the height of male students.

As per given,

[tex]\mu=158,\sigma=5[/tex]

The probability of male students who are between 145 cm and 170 cm

= [tex]P(145<X<170)[/tex]

[tex]=P(\dfrac{145-158}{5}<\dfrac{X-\mu}{\sigma}<\dfrac{170-158}{5})\\\\=P(-2.6<Z<2.4)\\\\=P(Z<2.4)-P(Z<-2.6)\\\\=P(Z<2.4)-(1-P(2.6))\\\\=0.9918-(1-0.9953)\\\\= $$0.9871[/tex]

Hence, the percentage of male students who are between 145 cm and 170 cm = 98.71%

Answer:

The mortgage balance is $175,000

Step-by-step explanation:

Answer:

See Explanation

Step-by-step explanation:

Given:

The expression is:

[tex]f^3+11g-4h[/tex]

The given values are [tex]f=3,\ g=2,\ h=7[/tex].

To find:

The value of the given expression for the given values.

Solution:

We have,

[tex]f^3+11g-4h[/tex]

After substituting [tex]f=3,\ g=2,\ h=7[/tex], we get

[tex]f^3+11g-4h=(3)^3+11(2)-4(7)[/tex]

[tex]f^3+11g-4h=27+22-28[/tex]

[tex]f^3+11g-4h=49-28[/tex]

[tex]f^3+11g-4h=21[/tex]

Therefore, the value of the given expression is 21.

Step-by-step explanation:

2/100 x 200 = 4

m(MLK)=130

m(MLK)=m(ZLK)+m(MLZ)

-> x+86+x+66=130

  2x+152=130

2x = -22

x = -11

m(ZLK)=86-11=75

Answer:

m = -1

Step-by-step explanation:

One can tell directly from the graph that the slope is negative.  

Moving from (-2, 0) to (0, -2), we see x increasing by 2 units (this is the run) and y decreasing by 2 units (this is the 'rise').  The slope is m = -2/2, or m = -1.

Answer:

25 (price of 1 mug)

40 ( price of 1 tumbler)

Step-by-step explanation:

15 x 17 = 255

625 ÷ (17+8)  = 25 (price of 1 mug)

25+15 = 40 ( price of 1 tumbler)

Answer:

When x = -1, f(x) = 2

Step-by-step explanation:

f(x) = (1/2)^x

When x = -4

f(x) = (1/2)^x

f(x) = (1/2)^-4

= 1 ÷ (1/2)^⁴

= 1 ÷ 1^⁴/2^⁴

= 1 ÷ 1/16

= 1 × 16/1

= 16

When x = -1

f(x) = (1/2)^x

= (1/2)^-1

= 1 ÷ 1/2^1

= 1 ÷ 1/2

= 1 × 2/1

= 1 × 2

= 2

When x = -1, f(x) = 2
