Answer:
sorry need pionts
Step-by-step explanation:
use the graph to answer the questions.
1) Write in standard form
2) Identify the foci and asymptotes
3) find the domain and range
Answer:
Example: Locating a Hyperbola's Vertices and Foci
The hyperbola is centered at the origin, so the vertices serve as the y-intercepts of the graph. To find the vertices, set x=0 x = 0 , and solve for y y . Therefore, the vertices are located at (0,±7) ( 0 , ± 7 ) , and the foci are located at (0,9) ( 0 , 9 ) .

equation of line is y=mx+c
where c is the point where the line intersects y axis. (0,0) in this case.
and m is the slope, which we need to find.
from the graph, when x=2, y=1. putting in above equation
1=2m+0
implies m=0.5
Answer:
$. 50 per pound
Step-by-step explanation:
We need to find the slope
We have two points (0,0) and (2,1.00)
m = (1-0)/(2-0)
=1/2
=.50

Determine the y-intercept of the graph of this equation: y - 3 = 2(x + 5)
Answer:
y intercept is 13
Step-by-step explanation:
y - 3 = 2(x + 5)
To find the y intercept, let x=0 and solve for y
y - 3 = 2(0 + 5)
y - 3 = 2(5)
y -3 =10
y-3+3 = 10+3
y = 13

According to the results for Patient 2 shown above, which antigens were present in Patient 2’s blood? Check all (if any) that apply. A antigen B antigen Rh antigen Patient 2 has Type ✔ AB– blood. Based on these results, which type(s) of blood can this patient safely receive? Check all that apply. A B AB O Also, the patient should receive blood that is for Rh.
Answer:
Blood is further classified as being either "Rh-positive" (meaning it has Rh factor) or "Rh-negative" (without Rh factor). So, there are eight possible blood types: O negative... blood type doesn't have A or B markers, and it doesn't have Rh factor
Blood type AB can also be applied

Use the svd() function in MATLAB to compute , the rank-1 approximation of . Clearly state what is, rounded to 4 decimal places. Also, compute the root mean square error (RMSE) between and .
Answer:
Here is the Matlab code.
Step-by-step explanation:
Matlab Code:
[tex]A = [1 2 2;3 4 5;6 7 8]\\[U,S,V] = svd(A)u1 = U(:,1)\\u2 = U(:,2)\\u3 = U(:,3)\\d1 = dot(u1,u2)\\c = cross(u1,u2)\\d2 = dot(c,u3)[/tex]
[tex]d1 =- 5.5511e-17\\c = -0.7172 0.6643 -0.2103\\d2 = 1[/tex]
Yes, since c = cross(u1,u2) is orthogonal to both u1 and u2. Hence is u3, thus the dot product with u3 is 1.

Answer:
96°
Step-by-step explanation:
The relevant relations are ...
the sum of arcs of a circle is 360°the measure of an inscribed angle is half the measure of the arc it intercepts__
The measure of arc HPQ is ...
arc HPQ = 360° -108° -60° = 192°
Then the measure of inscribed angle QRH is ...
∠QRH = (arc QPH)/2 = 192°/2

Bonjour, je suis en 4e et j’aimerais que vous m’aidiez avec cette feuille d’exercice s’il vous plaît ? (en précisent vos réponses).
Merci d’avance.
Step-by-step explanation:
1. Soit
T = le coût d'un ticket
5T + 1.8 = 35
T = (35-1.8)/5 = 6.64
On ne sait pas le coût d'un ticket de tramway! :(
2.
a.
1 h : 60 min
x : 18
x = 1*18/60 = 0.3, ou 0.3h
b. => 1h18m = 1.3h
3. 16 L : 4 h
a.
x L : 365*24
x = 365*24 * 16/4 = 35040 L
b.
1 m^3 = 1000 L : 5.2 euros
35040 L : y euros
y = 5.2*35040/1000 = 182.21 euros (au centième)
4.
a. Voir graphique ci-attachée.
b. On voit bien que tous les points tombent sur la droite passant par l'origine, donc la relation est linéaire, ou proportionnelle.
c. La hauteur requise pour 270L est de 100 cm, approximativement, selon la graphique.
Notez la ligne bleue horizontale.
d. L'équation de la capacité (C) versus la hauteur (h) est
C(h) = (8/3)h
Pour C=270, 270 = (8/3)h => h=270*(3/8) = 101.25

mark had 3/2 cans of paint and used 1/2 can for his room. what fraction of the paint did he use
Given:
Mark had [tex]\dfrac{3}{2}[/tex] cans of paint and used [tex]\dfrac{1}{2}[/tex] can for his room.
To find:
The fraction of the paint did he use.
Solution:
Total paint = [tex]\dfrac{3}{2}[/tex] cans
Paint used = [tex]\dfrac{1}{2}[/tex] can
The fraction of the paint did he use is:
[tex]\text{Required fraction}=\dfrac{\text{Paint used}}{\text{Total paint}}[/tex]
[tex]\text{Required fraction}=\dfrac{\dfrac{1}{2}}{\dfrac{3}{2}}[/tex]
[tex]\text{Required fraction}=\dfrac{1}{3}[/tex]
Therefore, Mark use [tex]\dfrac{1}{3}[/tex] of the paint.
How to write a solution to the equation x^2=5 using exponents and radicals
Answer:
x = sqrroot(5)
Step-by-step explanation:
The radical form of x²=5 is x= ±√5.
What is Radical form?The √ symbol that is used to denote square root or nth roots.
An expression with a square root is referred to as a radical expression. Radicand: A value or phrase included within the radical symbol.
Radical notation is the usage of a root in an expression, such as the square or cube root.
For example, radical form is ∛3 = √27.
Given:
x²=5
Now, we have to write it in the radical form.
So, we can write
x= ±√5
Hence, the radical form of x²=5 is x= ±√5.
