What do the measures of angles BDA and BEA and the fact that AD and AE are radii of circle A tell us about BD and BE
Font Sizes
Answers
Answer:
BD and BE are tangents to the circle
Step-by-step explanation:
Given
See attachment
Required
What does BD and BE represent?
From the attachment, we have:
[tex]\angle BDA = 90^\circ[/tex]
[tex]\angle BEA = 90^\circ[/tex]
[tex]Radii = AD\ and\ AE[/tex]
The measure of angles between a tangent and the radius of a circle is always [tex]90^\circ\\[/tex]
So, because [tex]\angle BDA = 90^\circ[/tex] and AD is a radius, then BD is a tangent to circle.
Similarly,; [tex]\angle BEA = 90^\circ[/tex] and AE being a radius implies that BE is a tangent to circle.

The value of the given expression.
Solution:
We have,
[tex]\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-9}{16}\times \dfrac{14}{25}[/tex]
It can be written as:
[tex]=\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-3\times 3}{2\times 2\times 2\times 2}\times \dfrac{2\times 7}{5\times 5}[/tex]
[tex]=\dfrac{-2\times 5\times (-3)\times 3\times 2\times 7}{3\times 7\times 2\times 2\times 2\times 2\times 5\times 5}[/tex]
Cancel out the common factors.
[tex]=\dfrac{-(-3)}{2\times 2\times 5}[/tex]
[tex]=\dfrac{3}{20}[/tex]
Therefore, the value of given expression is [tex]\dfrac{3}{20}[/tex].

Answers
Answer:
C. 10.5(12 + x) square feet
E. (126 + 10.5x) square feet
Step-by-step explanation:
A. 10.5(12x) square feet
B. (10.5 + 12 + x) square feet
C. 10.5(12 + x) square feet
D. 126x square feet
E. (126 + 10.5x) square feet
F. (22.5 + x) square feet
length of a living room = 12ft
width = 10 1/2 ft
The length of the living room is being expanded by X feet
New length of a living room = 12ft + x feet
new area of the living room = length × width
= 12ft + x feet × 10 1/2 ft
= (12 + x) 10 1/2
Note: 10 1/2 is equivalent to 10.5
= (12 + x) 10.5
= (126 + 10.5x) square feet
Options that applies
C. 10.5(12 + x) square feet

how many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22
Answers
Answer:
x = 4, y = -3
Step-by-step explanation:
{2x - y = 11
{x + 3y = -5
You can use the substitution method by solving for x in the second equation:
x + 3y = -5
Subtract 3y from both sides:
x = -3y - 5
Now, substitute this value for x into the first equation:
2x - y = 11
2(-3y - 5) - y = 11
Distribute:
-6y - 10 - y = 11
Add 10 to both sides:
-6y - y = 21
Combine like terms:
-7y = 21
Divide both sides by -7:
y = -3
Next, substitute this value for x into the second equation:
x + 3y = -5
x + 3(-3) = -5
Multiply:
x - 9 = -5
Add 9 to both sides:
x = 4

What is the area of this regular polygon?
Answers
Answer:
A=25√3 cm^2
Step-by-step explanation:
Since it is a regular triangle, all sides are equal to 10cm. The dotted line is a perpendicular bisector, which means that it seperates the triangle into two perfect halves. So a right triangle is formed. The bottom of the right triangle will be half of 10, and 10/2=5. So to find the missing side, use the pythagoreom theorem.
5^2+x^2=10^2
25+x^2=100
x^2=75
x= 5√3
The height of the triangle is found, so apply the formula for area:
A=1/2*5√3*10
A=25√3

Characteristics of Autocratic Governments
Explanation:
The definition is ‘a system of government by one person with absolute power.’
1. Lilly has two cousins. One of the cousins is 7 years older than Lilly. The other cousin is 3 years younger than Lilly. The product of Lilly’s cousins' ages is 24. How old is Lilly?
2. Jackie is building a rectangular football field that has an area of 6000 square yards. The football field must be 40 yards longer than its width. Determine the width of the football field, in yards.
3. James is reading a book and noticed the page numbers are consecutive integers whose product is 1640. What is the value of the larger page number?
Answers
Answer: a. 5 years
b. 60 yards
c. 41
Step-by-step explanation:
1. Let Lily's age be x.
One of the cousins is 7 years older than Lilly. The age will be = x + 7
The other cousin is 3 years younger than Lilly. The age will be = x - 3
Therefore, (x + 7)(x - 3) = 24
x² - 3x + 7x - 21 = 24
x² + 4x - 21 - 24 = 0
x² + 4x - 45 = 0
x² + 9x - 5x - 45 = 0
(x² + 9x) - (5x - 45) = 0
x(x + 9) - 5(x + 9) = 0
(x - 5)(x + 9) = 0
(x - 5) = 0
x = 0 + 5
x = 5
Therefore, Lily is 5 years
2. Let the width be represented by x
Therefore, length will be x + 40.
Area = length × width
6000 = x(x + 40)
x² + 40x = 6000
x² + 40x - 6000 = 0
x² + 100x - 60x - 6000 = 0
x(x + 100) - 60(x + 100) = 0
(x - 60)(x + 100) = 0
x - 60 = 0
x = 0 + 60 = 60
Therefore, the width is 60 yards
3. Let the consecutive numbers be x and x+1.
Therefore, x(x + 1) = 1640
x² + x = 1640
x² + x - 1640 = 0
x² + 41x - 40x - 1640 = 0
x(x + 41) - 40(x + 41) = 0
(x - 40) = 0
x = 0 + 40
x = 40
Larger number = x + 1 = 40 + 1 = 41

Which graph represents a quadratic function with a negative discriminant?
Choice 1
Choice 2
Choice 3
Choice 4
Answers
Answer:
Choice 4
Step-by-step explanation:
#4 because the graph does not intersect the x-axis
The graph that represents a quadratic function with a negative discriminant is graph 4.
What is a Discriminant?The part in the formula of a quadratic equation that helps us to know the nature of the roots of a quadratic equation is known as a discriminant.
D = b2 - 4ac,
If the value of the discriminant is greater than zero then the roots of the equation are real and distinct,If the value of the discriminant is equal to zero then the roots of the equation are real and same, andIf the value of the discriminant is less than zero then the roots of the equation are imaginary.Since for the value of the discriminant to be negative, the roots of the quadratic equation should be imaginary. Also, imaginary never intersects the x-axis of the graph.
Now, in the group of the graphs the only graph that does not intersect the x-axis of the graph or have imaginary roots is graph 4.
Hence, the correct option is graph4 (Bottom Right).
