sin(48°) = x / 1200ft. Multiply each side by 1200ft.
1200ft × sin(48°) = x.
x = 891.77 ft.

66.42
Step-by-step explanation:
66.42 is already rounded to the nearest hundredth.
Answer:
Step-by-step explanation:
yea
Answer:
Recall that a relation is an <em>equivalence relation</em> if and only if is symmetric, reflexive and transitive. In order to simplify the notation we will use A↔B when A is in relation with B.
<em>Reflexive: </em>We need to prove that A↔A. Let us write J for the identity matrix and recall that J is invertible. Notice that . Thus, A↔A.
<em>Symmetric</em>: We need to prove that A↔B implies B↔A. As A↔B there exists an invertible matrix P such that . In this equality we can perform a right multiplication by and obtain . Then, in the obtained equality we perform a left multiplication by P and get . If we write and we have . Thus, B↔A.
<em>Transitive</em>: We need to prove that A↔B and B↔C implies A↔C. From the fact A↔B we have and from B↔C we have . Now, if we substitute the last equality into the first one we get
.
Recall that if P and Q are invertible, then QP is invertible and . So, if we denote R=QP we obtained that
. Hence, A↔C.
Therefore, the relation is an <em>equivalence relation</em>.
Answer:
D. 1200 mg
Step-by-step explanation:
In order to find the solution we need to understand that a dosage of 20 mg/kg means that 20 mg are administered to the patient for each kg of his/her weight.
So, if the patient weight is 60 kg then:
Total drug X = (20mg/Kg)*(60Kg)=1200mg.
In conclusion, 1200 mg will be administered to the patient, so the answer is D.
