Answer:

T-intercept = 67

Step-by-step explanation:

Given

T = 44m + 67

Required

Calculate and interpret the t-intercept

To calculate the t-intercept, we simply set the number of minutes (m) to 0

i.e. substitute 0 for m in T = 44m + 67

T = 44 * 0 + 67

T = 0 + 67

T = 67

Hence, the T-intercept is 67

The interpretation is that the initial temperature when the oven is turned on is 67 degrees

ANSWER: 8  A_P_E_X  

Step-by-step explanation:

Plug the radius and the center point into the equation, and convert it to general form to get your answer.

The value of a is 4.

The standard equation of a circle is given by

(x -h)² + (y-k)² = r²

The equation given is

x² + y² +ax +by +c = 0

a = -h * 1

(h,k) represents the coordinate for the center of the circle

h = -4 , k =2

a = -(-4) *1 = 4

Answer:

1 1/2 + (-1/2) is also 1 1/2 - 1/2.

the result is 1 whole, and 1 whole is also the difference between 1 1/2 and 1/2.

Say you have half of a cheese piece, but your friend has 1 whole cheese piece plus half of a cheese piece.

He/She has 1 more cheese piece than you, right? That's the difference between you and your friend's cheese. 1 whole.

Answer:

Step-by-step explanation:

Before we can calculate the equation of the parabola in the form

y = ax²+bx, we need to get the value of a and b.

First we need to set up a simultaneous equation as shown;

since y = ax²+bx

dy/de = y' = 2ax + b

Substitute the point (2, 8) into the equation

y' = 2a(2)+b

y' = 4a + b

Since y' is also the slope of the equation y = 12x-16, hence y' = 12 on comparison.

The equation becomes;

12 = 4a+b

4a+b = 12 ........... 1

Since the point (2, 8) is also on the parabola, then it must satisfy the equation y = ax²+bx

substitute the coordinate;

8 = a(2)²+b(2)

8 = 4a + 2b

4 = 2a + b

2a+b = 4 ........... 2

Solve equations  1 and 2 simultaneously

4a+b = 12 ........... 1

2a+b = 4 ........... 2

Substract both equation

4a - 2a = 12-4

2a = 8

a = 4

substitute a = 4 into equation 2 and get b;

From 2; 2a+b =4

2(4)+ b = 4

8+b = 4

b = 4-8

b = -4

Substitute a = 4 and b = -4 into the equation of the parabola y = ax²+bx

y = 4x²+(-4)x

y = 4x²-4x

y = 4x(x-1)

Hence the required equation of the parabola is y = 4x(x-1)

Answer:

Step-by-step explanation:

1. P(≥30 | B) = P(≥30 & B)/P(B)

  P(≥30 | B) = 0.21/0.30 = 0.70

The probability that a B student did at least 30 minutes of homework is 0.70.

__

2. The probability that any student did at least 30 minutes of homework is shown in the column a the right end of the table: 0.70. This is the same as the probability that a B student did at least 30 minutes of homework. That is ...

  P(≥30 | B) = P(≥30)

Hence, the events "at least 30 minutes of homework" and "B student" are independent.

Explanation:

Correlation coefficients refer to the degree of relationship between two exclusive variables.

A weak correlation means that a change in one variable does not significantly affect or cause any reaction with the second variable.

For example, if the prices of coffee and the price of ballons are observed in the same period and found to have a correlation of +0.00006. This means that there is little or no correlation, or relationship, between the two variables. Weak relationships are usually between -0.1 and +0.1

Correlation coefficients can also be positive or negative.

It is positive if both factors seem to move in the same direction. As an example, if the price of stocks for Apple and Microsoft change in the same direction in the same period, they are said to have a positive correlation coefficient.

On the flip side, the correlation coefficient will be negative if the price of one stock moves upwards whilst the other moves downwards. A perfect negative relationship would read -1.

Answer:

  A) 1.3×10^37 ergs

  B) 1.435×10^3 mm

Step-by-step explanation:

A) The amount of energy will be the product of the energy rate and time:

  (3.9×10^33 ergs/s)×(3.25×10^3 s) =12.675×10^(33+3) ergs

  = 1.2675×10^(1+36) ergs

  = 1.2675×10^37 ergs ≈ 1.3×10^37 ergs

The mantissa of the result is the product 3.9×3.25, adjusted to have one digit left of the decimal point. The exponent of the result is the sum of the exponents of the factors, adjusted by 1 to match the adjustment in the mantissa.

The final value should be rounded to 2 significant figures, reflecting the precision of the sun's energy production.

B) A millimeter is a small fraction of an inch. 10^-3 mm is a small fraction of the width of a human hair, so 1.435×10^-3 mm is not a reasonable estimate of the distance between railroad tracks.

On the other hand, 1.435×10^3 mm is 1.435 m, almost 56.5 inches. This is a much more reasonable measurement of the distance between railroad rails.

  1.435×10^3 mm is more reasonable

Answer:

[tex]y=9.75x[/tex]

Step-by-step explanation:

The interval of the domain of the considered function for which the function is decreasing is none. The function is strictly increasing: Option D: The function is increasing only.

Suppose that the function is y = f(x)

If for an interval I, when x increases meanwhile staying in the interval I, the function's output decreases (or can stay same), then we say that the function is decreasing in the interval I.

This interval I was of values that x can take for this function, which is the domain of the considered function, so we say:

y = f(x) is decreasing function in an interval I if:

[tex]f(x+\delta) \leq f(x) \: \forall x \in I : x+\delta \in I[/tex]

If we have:

[tex]f(x+\delta) < f(x) \: \forall x \in I : x+\delta \in I[/tex], then the function is called strictly decreasing in the interval I.

Similarly, there increasing( [tex]f(x+\delta) \geq f(x) \: \forall x \in I : x+\delta \in I[/tex] ) and strictly increasing([tex]f(x+\delta) > f(x) \: \forall x \in I : x+\delta \in I[/tex] ) functions.

For this case, the function is:

[tex]h(x) = \left \{ {{2^x, x < 1} \atop \: \atop {\sqrt{x+3}, x \geq 1}} \right.[/tex]

The function is differentiable in either side of 1.

Sign of rate of function at a point tells whether its increasing or decreasing.

[tex]h'(x)= 2^x ln(2)[/tex]
We know that:

[tex]2^x > 0 \: \rm \forlall x \in \mathbb R[/tex]

And [tex]ln(2) \approx 0.69 > 0[/tex]

Thus, [tex]h'(x)= 2^x ln(2) > 0 \: \forall x \in \mathbb R[/tex]

So, rate is positive, the function is strictly increasing for this case.

[tex]h'(x) = \dfrac{1}{2\sqrt{(x+3)}}[/tex]

For all x > 1, [tex]\sqrt{x+3} > 0[/tex], and so as h'(x)

So rate is positive and therefore strictly increasing for this case too.

[tex]h(1+\delta) - h(1)= \sqrt{1+\delta + 3} - \sqrt{1+3} = \sqrt{4+\delta} - \sqrt{4} > 0 \forall \delta > 0[/tex]

So rate of the considered function is positive,so function is strictly increasing all over the domain.

Thus, the interval of the domain of the considered function for which the function is decreasing is none. The function is strictly increasing: Option D: The function is increasing only.
