Answer: (-4, -1)
Step-by-step explanation:
Starting at point (-4, -2) and translating 3 units up means we add 3 to -2.
So the new point is now (-4, 1).
Now we reflect over the x-axis which means the y-value of 1 becomes negative.
So the final point is (-4, -1)
Answer:
(-4,-1)
Step-by-step explanation:
when you translate it by 3 units up, it becomes (-4,-1). and when you reflect over the x axis, it becomes (-4,-1)

Determine the nature of the roots: 2x2 + 8x + 3 = 0
Answer:
the nature of the roots of an equation is real, distinct and irrational
Step-by-step explanation:
Given Data provided in the question according to the question is as follows:
[tex]2x^2 + 8x + 3 = 0[/tex]
where
a = 2 , b = 8 , c = 3
As we know that
Quadratic expression

Step-by-step explanation:
To use the SAS similarity theorem, you must show proportionality between corresponding sides, and congruence of the angle between them.
The answer shown above is the only answer choice that mentions an angle.
__
Comment on other choices
Choice B shows the three sides are proportional, so would be useful if the SSS similarity theorem were to be invoked. It isn't helpful for the using the SAS similarity theorem.
Choices C and D get the proportion statements wrong.
Answer:
RS/VU=ST/UT and Angle S congruent Angle U
A plane is descending onto the runway with an angle of depression of 55°. If it has 2.8 miles to go before landing (hypotenuse), what is the current altitude of the plane?
A. 4.9 miles
B. 3.4 miles
C. 4 miles
D. 1.6 miles
E. 2.3 miles
Answer:
Option C is correct
Step-by-step explanation:
Given: A plane is descending onto the runway with an angle of depression of 55°. Also, it has 2.8 miles to go before landing.
To find: current altitude of the plane
Solution:
Consider the attached image.
In ΔABC,
[tex]\angle ACB=55^{\circ}[/tex] (Alternate interior angles)
For any angle [tex]\theta[/tex],
[tex]tan \theta[/tex] = side opposite to angle/side adjacent to angle
[tex]\tan C=\frac{AB}{BC}[/tex]
Put [tex]\angle C=55^{\circ}\,,\,BC=2.8\,\,miles[/tex]
[tex]AB=2.8\,\tan 55^{\circ}=3.999\approx 4\,\,miles[/tex]
So, the current altitude of the plane is 4 miles.

6 ft and its $2 per ft
for two
The ribbon will cost $ _40_
Math is
AWESOME!
Answer:
$40 will be the total cost of the ribbon.
Step-by-step explanation:
To find the cost of ribbon to be put on the edges of rectangular banner, we need to:
1. Find the perimeter of the rectangle.
2. Multiply the perimeter with the per foot cost to find the total cost.
Let us find the perimeter first:
Perimeter of a rectangle is given as:
[tex]P = 2 \times \text{(length+width)}[/tex]
Here, the dimensions of rectangle are 4ft by 6ft.
So, perimeter = [tex]2 \times (4+6) \Rightarrow 20\ ft[/tex]
It is given that per foot cost is $2.
Total cost of the ribbon = [tex]2 \times 20 \Rightarrow $40[/tex]
$40 will be the total cost of the ribbon.
Ruben and Victor both track the number of miles they walk each day for 6 months. The data is normally distributed for each student.
Ruben had a mean μR of 5 miles with a standard deviation σR=1.1.
Victor had a mean μV of 4.4 miles with a standard deviation σV=1.4.
What are the probabilities that Ruben walked more than 6.1 miles and that Victor walked less than 5.8 miles? Select the probabilities that apply.
16%
34%
68%
545
95%
Answer:
Step-by-step explanation:
Let x be the random variable representing the number of miles that each person walked each day for 6 months. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
For Rueben,
µ = 5
σ = 1.1
the probability that Rueben walked more than 6.1 miles is expressed as
P(x > 6.1) = 1 - P( x ≤ 6.1)
For x = 6.1,
z = (4 - 6.1)/1.1 = - 1.91
Looking at the normal distribution table, the probability corresponding to the z score is 0.02807
P(x > 6.1) = 1 - 0.02807 = 0.97193
P(x > 6.1) = 0.97 × 100 = 97%
For Victor,
µ = 4.4
σ = 1.4
the probability that Victor walked less than 5.8 miless is expressed as
P(x < 5.8)
For x = 5.8,
z = (5.8 - 4.4)/1.4 = 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.8413
P(x < 5.8) = 0.84 = 84%

find the product
Answer:
4x^2 -25
Step-by-step explanation:
(2x + 5)(2x - 5)
FOIL
first: 2x*2x = 4x^2
outer : 2x*-5 = -10x
inner : 5*2x = 10x
last: -5*5 = -25
Add them together
4x^2 -10x +10x -25
Combine terms
4x^2 -25
Answer:
4x²- 25
Step-by-step explanation:
Let's use the FOIL (First, Outer, Inner, Last) method to solve:
(2x + 5)(2x - 5)
FOIL
First:
(2x + 5)(2x - 5)
2x(2x)
= 4x²
FOIL
Outer:
(2x + 5)(2x - 5)
2x(-5)
= -10x
FOIL
Inner:
(2x + 5)(2x - 5)
5(2x)
= 10x
FOIL
Last:
(2x + 5)(2x - 5)
(5)(-5)
= -25
Let's put it all together:
4x² - 10x + 10x - 25
Combine like terms:
4x² - 10x + 10x - 25
4x²- 25
Therefore, the product is 4x²- 25.
A triangle can have at most______right angle.
A. 4
B. 1
C. 0
D. 2
Answer:
B, 1 right angle
Step-by-step explanation:
Triangles don't have the same length of there sides. The sides are uneven which makes the triangle unique. Also, right triangles only have 1 right angle
Hope this helps
Mark brainliest pls
Answer:
B
Step-by-step explanation:
Another way you can think about it is by thinking about the total possible angle sum. The angles in a triangle must sum to 180, so if there are 2 or more right angles, then you either cant have a 3rd angle because thats already at or over 180 degrees. That is why it must be 1.
What answer is equivalent to -4(b + 2) - 36?
Answer:
− 4 b − 44
Step-by-step explanation:
Answer:
-4(b + 11)
Step-by-step explanation:
-4(b + 2) - 36 (multiply -4 into parentheses via distributive property)
= b(-4) + 2(-4) - 36
= -4b -8 - 36
= -4b - 44 (this could be an answer, but we can still simplify further by factoring out -4)
= -4(b + 11)

Adam plans to choose a video game from a section of the store where everything is 75% off. He writes the expression −0.75 to find the sale price of the game if the original price is dollars.
Rena correctly writes another expression, 0.25, that will also find the sale price of the game if the original price is dollars.
Use the drop-down menus to explain what each part of Adam's and Rena's expressions mean.
Answer:
Step-by-step explanation:
Adam plans to choose a video game from a section of the store where everything is 75% off.
The expression written by him for this situation is d - 0.75d.
Here, the part d represents the sale price before discount and the part 0.75d is the discount amount.
The expression written by Rena is 0.25d.
Here, the part 0.25d is the price after discount. Since 75% is the discount, the rate after disount is 25% and 25% of d is 0.25d.

What is the probability that the reader’s favorite is Rowling given that the reader is a teen?
Leave the answer in decimal form to 3 decimal places.
Answer:
Probability = 0.500
Step-by-step explanation:
If it is given that the reader is a teen, we have a total of 80 readers, where 40 of those readers have Rowling as their favorite.
So the probability that the reader's favorite is Rowling given that the reader is a teen is the number of teen readers that have Rowling as favorite (40) over the total number of teen readers (80)
Probability = 40 / 80 = 0.500
