5. Find the vertex and length of the latus rectum for the parabola.
Answer: (2,5)
Step-by-step explanation:
To find the x coordinate of the vertex, you will set x-2=0 and solve for x
x-2=0
+2 +2
x = 2
Now since we know the vertex has an x coordinate of 2 we have to solve for y by plotting in the x value.
y= 1/2(2-2)^2 + 5
y = 0 +5
y =5
(2,5)

find the zeros of ply nomial x2-3 and verify the relation ship
Answer:
[tex]x=\pm \sqrt{3}[/tex]
Step-by-step explanation:
Consider the given polynomial is
[tex]P(x)=x^2-3[/tex]
We need to find the zeros of the given polynomial.
Now,
[tex]P(x)=0[/tex]
[tex]x^2-3=0[/tex]
Add 3 on both sides.
[tex]x^2=3[/tex]
Taking square root on both sides.
[tex]x=\pm \sqrt{3}[/tex]
Therefore, zeros of the polynomial P(x) are [tex]-\sqrt{3} \text{ and }\sqrt{3}[/tex].
To verify the relationship, put [tex]x=\sqrt{3}[/tex] in P(x).
[tex]P(\sqrt{3})=(\sqrt{3})^2-3=3-3=0[/tex]
Put [tex]x=-\sqrt{3}[/tex] in P(x).
[tex]P(-\sqrt{3})=(-\sqrt{3})^2-3=3-3=0[/tex]
Since P(x)=0 for both values, therefore relationship verified.

Answer:
x=70
z=20
y=30
Step-by-step explanation:
first find x: the sum of straight angle is 180
x+110=180
x=180-110=70
now find z: the sum of the angles of triangle is 180:
x=70, right angle=90
z+70+90=180
find y:
y+110+40=180
y=180-150=30
z=180-160=20
Answer:
x=70 degrees, y= 30 degrees, z=20 degrees
Step-by-step explanation:
110+x=180 => straight angle def.
180-110+40=y => def. of angles in triangle
x( 70 degrees) +90+z=180, z= 20 => angles in triangle

Answer:
e=15.8
Step-by-step explanation:
Well we use the law of cosines
e^2=11^2+6^2-2(11)(6)cos(134)
[tex]e^{2} =121+36-132cos134\\e^2=157-132cos143\\e^2=248.694....\\e=15.8[/tex]
Answer:
15.8
Step-by-step explanation:
Using Cosine rule
a² = b²+c²-2bcCos A
a = e
b = 11
c = 6
A = 134°
e² = 11²+6²-2•11•6 × Cos 134
" = 121+36 -132× -0.69466
" = 157 + 91.69512
" = 248.69512
e² = 248.6951
e = (248.6951)½
e = 15.7701
nearest tenth = 15.8
The geometric mean and one extreme are given. Find the other extreme.
33)√35 is the geometric mean between p and q. Find q if p = √7
Answer:
q= 5
Step-by-step explanation:
Geometric mean of two term p and q is = [tex]\sqrt{pq}[/tex]
we have
p = √7
geometric mean = √35
Thus, using the formula of geometric mean
√35 = √7*q
[tex]\sqrt{35} = \sqrt{7q} \\[/tex]
squaring both sides
[tex]\sqrt{35}^2 = \sqrt{7q} ^2\\=>35 = 7q\\=> q = 35/7 = 5[/tex]
Thus, q= 5

Answer:
3/10
3/10
Step-by-step explanation:
0,1,2,3,4,5,6,7,8,9 are in a box
odd primes are 3 and 5 and 7 ( 1 is neither prime nor composite)
There is a total of 10 numbers
P( odd prime) = number of odd primes / total = 3/10
perfect squares greater than 0 are 1,4,9
P( perfect squares) = number of perfect squares / total = 3/10
Answer: 3/10(the first one)
Step-by-step explanation: So, prefect squares are numbers that are divisible by two numbers multiplied by them selves, 1 is 1 x 1 4 is 2 x 2 and 9 is 3 x 3 so 3 numbers out of 10 from 0 to 9 are perfect squares! Hope this helps, 15402256.

A. -2
B. 0
C. 1
D. Undefined
Hey there! :)
Answer:
B. 0
Step-by-step explanation:
On the graph, the line is a horizontal line. This means that there is no change in the y-value across the domain.
Thus, the graph has a slope of 0.
Answer:
B. 0
Step-by-step explanation:
Use the following formula to solve for slope:
m (slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (0 , -2)
(x₂ , y₂) = (2 , -2)
Plug in the corresponding numbers to the corresponding variables:
m = (-2 - (-2))/(2 - 0)
Simplify:
m = (-2 + 2)/(2 - 0)
m = 0/2 = 0
B. 0 is your slope.

According to a nutrition coach, a 100 kg person should eat
0.07 kg of protein. What percent of a person's body weight should they eat
in protein? (round to 2 decimal places) *
Answer:
0.07%
Step-by-step explanation:
This equation is solving for what percentage of 100 kg is 0.07 kg.
1. Set up the equation
[tex]\frac{0.07}{100}[/tex] = [tex]\frac{x}{100}[/tex]
0.07 kg out of 100 kg is equal to x out of 100 because x represents the percentage and percentages are out of 100.
2. Solve by cross multiplying
100x = 7
3. Solve for x by dividing both sides by 100
x = 0.07
The answer is 0.07%

Hey there! :)
Answer:
SA = 144 cm².
Step-by-step explanation:
Find the surface area by calculating the areas of each of the lateral sides and bases:
In this instance, the bases are triangles, so the formula A = 1/2(bh) will be used:
Bases:
A = 1/2(bh)
A = 1/2(4·3)
A = 1/2(12)
A = 6 cm².
There are two bases, so:
6 × 2 = 12 cm²
Find the areas of the lateral sides using A = l × w:
5 × 11 = 55 cm²
4 × 11 = 44 cm²
3 × 11 = 33 cm²
Add up all of the areas:
12 + 55 + 44 + 33 = 144 cm².
Answer:
144 cm^2
Step-by-step explanation:
So, first find the area of the triangle. To find that you need to use the formula A = bh ÷ 2 (Area = base x height ÷ 2)
A = (4)(3) ÷ 2
A of triangle = 6
Since there are 2 triangles, you need to multiply the area by 2, which equals 12.
To find the area of the rectangles, you need to use the formula A = lw (Area = length x width)
For the first rectangle,
A = 11 x 5
A = 55
For the second rectangle,
A = 4 x 11
A = 44
For the third rectangle,
A = 3 x 11
A = 33
Now, you need to add the areas of the triangles and rectangles together to get your surface area.
12 + 55 + 44 + 33 = 144cm^2
So, the surface area of the triangular prism is 144 cm^2.
Mr. Martin’s math test, which is worth 100 points, has 29 problems. Each problem is worth either 5 points or 2 points. Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points. x + y = 29, 5x + 2y = 100
Answer:
14 problems worth 5 points and 15 problems worth 2 points
Is the correct answer
Step-by-step explanation:
The solution are;
⇒ x = 14
⇒ y = 15
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The system of equation for given condition is;
⇒ x + y = 29, 5x + 2y = 100
Now,
Since, The system of equation for given condition is;
⇒ x + y = 29 ..(i)
⇒ 5x + 2y = 100 ..(ii)
Solve both the equation, we get;
⇒ 5x + 5y = 145
Subtract from (ii), we get;
⇒ 5y - 2y = 145 - 100
⇒ 3y = 45
⇒ y = 15
And, x + y = 29
x + 15 = 29
x = 29 - 15
x = 14
Thus, The solution are;
⇒ x = 14
⇒ y = 15

Possible values for the area A of the rectangle shown are 12 ≤ A ≤ 36. Write and solve a compound inequality to find the possible values of x. Are these values all viable in this situation?I really need help
Answer:
x can take any value and are viable in this situation if and only if it is a positive number
Step-by-step explanation:
We know that the area of a rectangle is given by:
A = x * y
So if we replace we have:
12 ≤ x * y ≤ 36
We divide by y, and we have:
12 / y ≤ x ≤ 36 / y
Which means that the value of x depends on y, that is to say if y is worth 1, the inequality would be:
12 ≤ x ≤ 36
In the event that y is equal to 2:
12/2 ≤ x ≤ 36/2
6 ≤ x ≤ 18
Which means, that depending on y, x can take any value and are viable in this situation if and only if it is a positive number.

For a rectangle of length L and width W, the area is given by:
A = L*W
We will find that the solution is: 3/2 ≤ x ≤ 11/2
Here we have:
L = 3
W = 2x + 1
Then the area equation is:
A = 3*(2x + 1) = 6x + 3
And we also have the inequality:
12 ≤ A ≤ 36
Replacing A with the equation we get:
12 ≤ 6x + 3 ≤ 36
Now we solve this for x:
12 - 3 ≤ 6x ≤ 36 - 3
9 ≤ 6x ≤ 33
Now we divide both sides by 6.
9/6 ≤ x ≤ 33/6
3/2 ≤ x ≤ 11/2

Adult 7 43 50
Children 22 28 50

Probability is expressed as
Number of favorable outcomes/number of total outcomes
For the probability that an adult has side effects,
Total number of outcomes = 50
Number of favorable outcomes = 7
Probability that an adult has side effects = 7/50 = 0.14
For the probability that a child has side effects,
Total number of outcomes = 50

Ms. Daffy tells you that the longest side of her right-triangular garden is 26m and one of the sides is 14m. A. She asks you to find the other side of the garden.
Answer:
22m
Step-by-step explanation:
The computation is shown below:
Since it is a right-triangular garden so we use the pythagoreus theorem
As we know that
The C^2 refers to the longest side of the right-triangular garden
So,
a^2 + b^2 = c^2
a^2 + 14^2 = 26^2
a^2 + 196 = 676
a^2 = 480
So a = 22m
Hence, the other side of the garden is 22m
