Evaluate: f(-3) =
Answer:
f(-3) = 0
Step-by-step explanation:
The question is asking you to evaluate the function when x = -3. Therefore, substitute -3 in for x and simplify.
f(x) = x² + 7x + 12 <---- Original equation
f(-3) = (-3)² + 7(-3) + 12 <---- Substitute -3 for x
f(-3) = 9 + 7(-3) + 12 <---- Square -3
f(-3) = 9 - 21 + 12 <---- Multiply 7 x -3
f(-3) = 0 <---- Combine terms

Based on the vertical angles theorem, the measure of angle 1 is: 48°.
What are Vertical AnglesVertical angles are always directly opposite each other and are formed when two straight lines crosses each other.
In the diagram given, the angle that is directly opposite angle is 48°, since it is an alternate angle to 48° formed on lines m and n (lines k and l are parallel lines).
Therefore:

If the triangles are congruent, then angle K will be the same as angle N
The triangles are congruent and the measures of angle ∠K ≅ ∠N
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the first triangle be ΔJKL
Let the second triangle be ΔMNP
Now , the triangles are congruent
So , ΔJKL ≅ ΔMNP ( given )
And , Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
So , the measures of angles are also similar
Hence , the angles are similar ( ∠K ≅ ∠N )

he Anwar family is planning to build a new home. They have hired 2 different architects to create blueprints for the house. Anderson Architects uses a scale of 1 in. to represent 1.5 feet. Charleston Architects uses a scale of 1.5 inches to represent 1 foot. If each group draws a room that is 12 inches by 12 inches on the plans, what is the difference in size in real life of the two drawings?
The difference in sizes in real life of the two scale drawing is 10 feet.
How to use scale to find the real length?They hired two different architect to create a blueprints for the house.
Anderson Architects uses a scale of 1 in. to represent 1.5 feet.
Therefore,
1 inches = 1.5 feet
Real life size of 12inches by 12 inches
12 inches = ?
size = 12 × 1.5 / 1 = 18 feet
Charleston Architects uses a scale of 1.5 inches to represent 1 foot.
Therefore,
1.5 inches = 1 foot
Hence,
Real life size of 12inches by 12 inches

[tex]\sf Half \ Life : A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }[/tex]
where A is final amount, Ao is initial amount, t is time taken, h is half life
Here given:
initial amount: 400 millicuries
final amount: 3.125 millicuries
half life: 8 days
time taken: ?
Hence solve for time taken:
[tex]\sf \rightarrow A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }[/tex]
insert values given
[tex]\sf \rightarrow 3.125 = 400 \ x \ (\dfrac{1}{2} )^{\dfrac{t}{8} }[/tex]
divide both sides by 400
[tex]\sf \rightarrow (\dfrac{1}{2})^{\dfrac{t}{8}}=0.0078125[/tex]
