The value of tan∠A form the right angled triangle ABC is 1.
Trigonometric ratioTrigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Given that △ABC be a right triangle with m∠C = 90°. Also, tan∠B = 1. Hence:
tan∠A = (tan∠B)⁻¹ = 1

Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
x(x + 6) = 5(5 + 3)
x² + 6x = 5 × 8 = 40 ( subtract 40 from both sides )
x² + 6x - 40 = 0 ← in standard form
(x + 10)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 10 = 0 ⇒ x = - 10
x - 4 = 0 ⇒ x = 4
x > 0 then x = 4
(11)
Given a secant and a tangent from an external point to the circle, then
The square of the tangent is equal to the product of the external part and the whole of the secant, that is
x(x + 10) = 12²
x² + 10x = 144 ( subtract 144 from both sides )
x² + 10x - 144 = 0 ← in standard form
(x + 18)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 18 = 0 ⇒ x = - 18
x - 8 = 0 ⇒ x = 8
x > 0 then x = 8
Which equation of the least squares regression line most closely matches the data set?
yˆ=−0.31x+37.3
yˆ=−0.09x+11.5
yˆ=−10.1x+118.8
yˆ=−2.3x+97.9
Answer:
I can confirm that the answer above is correct.
Step-by-step explanation:
Hope this helps. :D
The equation of the least squares regression line which is most closely matches the data set is yˆ=−10.1x+118.8
What is linear regression?Linear regression is a type of regression which is used to model the data having linear relationship between the variables. The regression line can be given as,
[tex]\hat y=bX+a[/tex]
The data given in the problem is,
x 2 4 6 8 10y 100 83 50 35 23Mean of x and y values,
[tex]\mu_x=\dfrac{2 +4 +6 +8 +10}{5}=6\\\mu_y=\dfrac{100 +83 +50 +35 +23}{5}=58.2[/tex]
Here, in this data points, the sum of the squares is 40 and sum of the products is -404. The value of b is,
[tex]b=\dfrac{-404}{40}\\b=-10.1[/tex]
The value of a is,
[tex]a=58.2-(10.1\times6)\\a=118.8[/tex]
Put the values in the above equation,
[tex]\hat y=-10.1X+118.8a[/tex]
Thus, the equation of the least squares regression line which is most closely matches the data set is yˆ=−10.1x+118.8

Rewrite each expression by combining like terms.
13p - 4p + 6q
Answer:
You answer would be 15p
Step-by-step explanation:
13p - 4p + 6p
9p + 6p
15p
Answer:
9p + 6q
Step-by-step explanation:
Rewrite each expression
Combine like terms
13p - 4p + 6q
_____________________
When we have like terms, we can only add the ones that have the same symbols as endings, such as variables, exponents, etc. Therefore :
Add "p" values together :
13p - 4p
9p.
Now rewrite the expression, we cannot combine like terms with "p" and "q" because they are not the same variable :
9p + 6q

8. Let angle A and angle B be acute angles in two right triangles. Calculate the angle and
round to the nearest tenth of a degree.
a. sin A = 0.87
b. cos B = 0.15
9514 1404 393
Answer:
a. 60.5°
b. 81.4°
Step-by-step explanation:
Inverse functions are used to find the angle value for a given trig function value.
a) arcsin(0.87) ≈ 60.5°
b) arccos(0.15) ≈ 81.4°
__
On many calculators, these functions are accessed using a 2nd or Shift key. They are often labeled as sin⁻¹ and cos⁻¹. The calculator will have a mode setting that needs to be set to "Degrees" if you don't want the angle in radians or grads.
