given the quadratic function y=x^2+ax+b, the minimum value is -3, and the graph passes through point (1,1). find the values of the consists a and b.​

Step-by-step explanation:

this means a triangle with one angle 30°, a second angle 60°, and the third angle 90°.

the sides of such a 30-60-90 triangle are always in the ratio of 1 : √3 : 2

that means the Hypotenuse is twice the length of the shorter leg. and the longer leg is square root of 3 times longer than the shorter leg.

30-60-90 Theorem: If a triangle has sides in the ratio x: x 3: 2 x and angles of 30, 60, and, then it is a triangle. The longer leg, the hypotenuse, and the shorter leg are always the same. The Pythagorean Theorem can be used in their place if you ever forget these theorems.

Logarithm ln3 is approximately 1.682.

Logarithm, the exponent or power to which a base must be raised in order to produce a specific number.

The linear approximation of the natural logarithm function near x=e is given by y ≈ ln(e) + (y'(e))(x-e), where y'(e) is the derivative of the logarithm function at x=e.

Since ln'(x) = 1/x, we have y'(e) = 1/e.

Substituting x=3 and e=2.71828... into the approximation, we get:

ln(3) ≈ ln(e) + (1/e)(3-e) = ln(e) + (3-e)/e

ln(e) = 1, so the result is:

ln(3) ≈ 1 + (3-e)/e ≈ 1 + 0.682 ≈ 1.682.

Hence, ln3 = 1.682.

The linear equation of line will be y=4/7x-6/7.

What is a linear equation ?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form

Ax + B = 0

e.g. x-10=0. Here, x is a variable, A is a coefficient and B is constant.

The standard form of a linear equation in two variables is of the form

Ax + By = C

e.g. 2x-4y=10. Here, x and y are variables, A and B are coefficients and C is a constant.

Now,

From graph take two point on line

(x1,y1),(x2,y2)=(5,2)(-2,-2)

As standard equation of a line is y=mx+c

where m=slope and c=constant

m=(y2-y1)/(x2-x1)

m=(-2-2)/(-2-5)=4/7

then equation of line will be

y-y1=4/7(x-x1)

y-2=4/7(x-5)

y=4/7x-20/7

Hence,

           The linear equation of line will be y=4/7x-6/7 in form of y=mx+c.

Answer:

The slope of the line that is perpendicular to y = 4x + 6 is the negative reciprocal of the slope of y = 4x + 6, which is -1/4.

We can use the point-slope form of a line, y - y1 = m(x - x1), to find the equation of the line that passes through the point (8, -4) and has a slope of -1/4, where m = -1/4 and (x1, y1) = (8, -4).

Plugging in the values, we get:

y - (-4) = -1/4 (x - 8)

y + 4 = -1/4 x + 2

Multiplying both sides by 4, we get:

4y + 16 = -x + 8

Adding x to both sides, we get:

4y + 16 + x = 8

y = -x/4 - 2

So the equation of the line that is perpendicular to y = 4x + 6 and passes through the point (8, -4) is y = -x/4 - 2.

The stopping distance of regular tires on glare ice is estimated by the function D(F) = 2F+115, where D(F) is the stopping distance in feet and F is the air temperature in degrees Fahrenheit.

(a) D(0°) = 115 feet, D(-20°) = 95 feet, D(32°) = 147 feet

(b) The domain should be restricted to [-57.5°,32°] because the function D(F) gives a negative value when F is less than -57.5°, which is not physically possible. The function is also not defined for temperatures greater than 32° because the stopping distance is not a linear function of the temperature at higher temperatures.

A linear equation is an algebraic equation with simply a constant and a first-order (linear) component of the form y=mx+b, where m is the slope and b is the y-intercept. The above is sometimes referred to as a "linear equation with two variables," where y and x are the variables.

Ax+By=C is the typical form for linear equations in two variables. 2x+3y=5, for example, is a simple linear equation. It is rather simple to get both intercepts when an equation is stated in this way (x and y).

Since both variables are independent but they have the same probability parameter, you can interpret that like if the experiment that models each try in both variables is the same. When you sum both random variables toguether, what you obtain as a result is the total amount of success in n1+n2 tries of the same experiment, thus X1+X2 have distribution Bi(n1+n2, p).

Note that, if X2 = k, then X1+X2 = 1 is equivalent to X1 = 1-k. Since X1 and X2 are independent, then P(X1+X2 = 1| X2 = K) = P(X1=1-k|X2=k) = P(X1 = 1-k).

If k = 0, then this probability is equal to P(X1 = 1) = np(1-p)ⁿ¹⁻¹

If k = 1, then it is equal to P(X1 = 0) = (1-p)ⁿ¹

Thus,

P(X1+X2 = 1) = P(X1+X2 = 1| X2 = 1) * P(X2=1) + P(X1+X2 = 1| X2 = 0) * P(X2 = 0) = (1-p)ⁿ¹ * np(1-p)ⁿ²⁻¹+ (1-p)ⁿ²*np(1-p)ⁿ¹-¹
